ISUTAMI KBA-L long linear bearing , also known as KBA-L extended linear bearing unit, KBA-L extended linear slide unit or KBA-L extended linear case housing (unit), is a suitable series for European market. L is an abbreviation for Long. This model consists of a long type aluminum housing with 4 fixing holes as well as two KB standard linear bearings. There is an oil hole on the unit side and one circlip on each end in the proper position. There are also two rubber seals (UU) at both ends of the linear bearing to keep back debris or ball bearing contamination. The aluminum casing is applied because it is small and lightweight, this kind of material has strong corrosion resistance.

KBA-L Linear Bearing Pillow Block Features

The KBA-L long linear bearing pillow block housing is a closed, double-length European metric version. The two KB standard linear bearings are mounted in the housing and arranged in a straight line in the aluminum casing. Advantages of the bearing bushing include less tilt or friction, less wear over time, and better machining results.

If you are manufacturing CNC milling machines, milling machines or lathes that require precise linear motion, it is a perfect solution to install this long aluminum bearing housing with KB standard linear bearings. Aluminum housing size range: length (L) ranges 58-230mm (matching KB standard linear bearing length (L) ranges 25-100mm); width (W) ranges 34-122mm; height (F) ranges 22-102mm. The minimum combined size of the specification KBA8L is 58*34*22mm, and the largest combined specification KBA50L is 230*122*102mm. These data are basically the same as the SMA-L extended type linear bearing pillow block, except that the KBA-L series has no diameter of 12mm and 35mm. The aluminum housing has four CNC drilled holes, threaded holes and countersunk holes of the same size M4-M10, which can be easily and safely mounted to almost any linear motion system.

A typical CNC system consists of a linear shaft of matching diameter, ranging from 8 to 60 mm in diameter, mounted on both ends of the shaft by two end supports, and the housing of the extended linear bearing runs straight along the shaft. Most CNC machines and 3D printers have two such components mounted side-by-side, using a housing as a stand to support the mobile platform. This is a long unit able to be mounted from above or below, making it easy to incorporate into the intended system. Positioning and precision enhancements are facilitated with one of the side aspects serving as datum face. The extruded aluminum case has undergone sufficient post-extrusion heat treatment to create a compact, lightweight and precision item.

ISUTAMI pillow block insert bearing, also known as ISUTAMI insert spherical ball bearing, is one of the main components for the bearing unit, which is usually mounted inside the housing and combined with housings made of different materials. The bearing belongs to a kind of ball bearing, and the main material is 52100 series bearing steel. The both sides of insert bearing are generally sealed with a rubber ring to prevent dust from entering the bearing and to prevent internal grease from overflowing. The outer ring of the bearing is in spherical shape and can be fitted to the spherical inner ring of the housing. The inner ring of the bearing has an extension at one side, and this extended portion is used to fix the matching round shaft.

Insert Bearing Features

We also divide the insert ball bearings into two types: one is a set screw lock type and another is an eccentric collar locking type according to the difference in this part. On the inner ring of the set screw lock type, there are two fixing screws distributed at an angle of 120°. When the shaft is inserted into the inner bore, the shaft can be tightened by fix the screw in the proper position; The ring has no set screw on the inner ring of an eccentric collar lock , but the round shaft can be mounted by matching the blackened collar. Compared with the way of fixing the screw lock, the installation method of the eccentric ring locking is more self-adjustable, and the round shaft will not be completely stuck, besides, the round shaft can rotate synchronously with the bearing. Based on the diameter of inner ring, we can also divide the bearings into a wide inner ring one and a narrow inner ring one.

ISUTAMI insert bearings are greased during the factory's production process, so they are pre-lubricated. The material of the outer casing that is matched with this series of bearings, commonly are cast iron, galvanized pressed steel, thermoplastic materials, etc. These materials have anti-corrosion functions. Some bearing units can work continuously in harsh environments, and some bearing units are with a little light duty and can be installed in highly mobile equipment.

ISUTAMI provides four types of insert bearings for the set screw locking inner ring: SER, UC, SB, CSB, and the bearings series with eccentric collar locking inner ring are HC, SA, CSA.

1. Four Components of Air Conditioning and Refrigeration System

The four components of air conditioning refrigeration system are evaporator, condenser, compressor and throttle valve. Air conditioning can be refrigerated or heated. Condenser is one of the four major components of air conditioning refrigeration system. Condenser can take away the heat absorbed by evaporator.

2. The working principle of Honda ac condenser replacement:

The working principle of the condenser is mainly based on the second law of thermodynamics. The working principle of the condenser is analyzed and explained in detail through the following schematic diagram.

Detailed analysis of the working principle of condenser: Condenser air conditioning system components can transfer heat from the tube to the air near the tube in a quick way. Most of the condensers on automobiles are installed in front of the water tank. It is a device for converting gases or vapors into liquids.

For some applications, the gas must pass through a long tube (usually coiled into a solenoid) to dissipate heat to the surrounding air. Thermal conductive metals such as copper are often used to transport steam. In order to improve the efficiency of the condenser, heat sinks are often attached to the pipeline to accelerate heat dissipation. The radiator is a flat plate made of good thermal conductive metal. This type of condenser usually uses a fan to force air through the radiator and take the tropics away. Generally, the refrigeration principle of refrigerators is that the compressor compresses the vapor with lower pressure into vapor with higher pressure, which reduces the volume of vapor and increases the pressure. The compressor sucks the working substance vapor with lower pressure from the evaporator and sends it to the condenser after the pressure rises. The liquid with higher pressure condenses in the condenser and is throttled by the throttle valve.

3. The main uses of Honda ac condenser replacement:

1) As one of the four major components of refrigeration system, the function of condenser is to take away the heat and cold absorbed by evaporator.

2) Many condensers are used in power plants to condense the steam discharged from turbines.

3) Condensers are used in refrigeration plants to condense refrigerating vapors such as ammonia and fr-eon.

4) Condensers are used to condense hydrocarbons and other chemical vapors in petrochemical industry. In the distillation process, the device that converts vapor into liquid is called condenser. All condensers operate by taking away heat from gases or vapors.

Through further understanding of the condenser, it will be helpful for us to maintain the condenser in the future. As the main material of condenser is copper and steel carbon, corrosion leakage often occurs between welds, which will cause environmental pollution. Therefore, in view of the anti-corrosion problem of condenser, polymer composites can be used and regular cleaning should be paid attention to.

According to the basic principle of "Where there is demand, where is production", Honda actively promotes the modernization system and develops, produces and sells products adapted to the needs of customers in different regions (including 92 production bases around the world, including China, and 13 research and development institutions at home and abroad).

As an international enterprise to promote localization, it not only means to integrate into local customs and culture, but also means to share the same "ideal" and "idea" with people all over the world, to share all business resources, and to carry out various activities at the same time.

The Honda, which started from the manufacture of bicycle auxiliary engines, has been developing not only in the field of modern vehicles such as automobiles and motorcycles, but also in the field of general products, which involves various industries and entertainment industries.

The internal pipeline of the hyundai sonata intercooler often contains dirt such as sludge and colloid, which not only narrows the air passage, but also reduces the cooling and heat exchange capacity. Therefore, the hyundai sonata inter-cooler must be maintained and cleaned. In general, the internal of the inter-cooler should be cleaned and inspected every year or when the engine is overhauled or the water tank is welded.

Cleaning method: add 2% soda water solution (temperature should be 70 - 80 C) into the intercooler, fill it up, wait 15 minutes to see if there is leakage in the inter-cooler. If there is no leakage, shake back and forth, repeat several times, pour out the lotion, then fill in clean water solution containing 2% soda for washing, until it is cleaner, then add clean hot water (80-90 C) for cleaning, until the released water is clean. If there is oil stain on the outside of intercooler, alkali water can also be used for cleaning. The method is to soak the oil stain in alkali solution and remove it with a brush until it is clean. After cleaning, the water in the intercooler is blown dry or naturally cooled by compressed air or the connecting pipe between the inter-cooler and the engine is not connected before installing the inter-cooler. The engine is started, and the engine intake pipe is connected when the outlet of the inter-cooler is dry. If serious dirt is found in the core of the inter-cooler, the leaks in the air filter and the intake pipes should be carefully checked and troubleshooted.

U&C carries a full line of replacement radiators and intercoolers for your tractor, combine, or harvester. Whatever brand you use to farm with, you can search it on our website. If you failed to find your required radiators, welcome to contact us.

With over 17 years experience in the cooling system manufacture, we can make radiators as required.

Radiator is an essential part of all the internal combustion and gasoline engines in the automobiles. The tractors are also acted with efficient and heavy-duty radiators for optimum engine performance in highly demanding work conditions. Radiators used for automotive applications are meant to provide cooling effect to the engine. With a radiator in place, the engine will retain its best temperature to work as expected.

The cooling system is responsible for maintaining an optimum temperature in the truck engines. And radiator is an important part of the cooling system of a tractor.

Agricultural radiators are generally placed in the front of the engine bay. In the engine block, liquid coolant is warmed by the friction created by the engine. Then the hot liquid coolant is pumed into the radiator. Because of the coolant, fanned air contacting the large surface area of the radiator, the liquid is cooled.

The construction of the agricultural radiators is simple. So it is reparable when there is a mechanical breakdown. Typical problems with the radiators are degradation of materials, leaks in header tanks, and loss of coolant.

An agricultural radiator is used as a heat exchanger in internal combustion engines. It cools the engine by replacing the heat from the hot coolant with cooled coolantants with air blown by the fan. It is generally made of aluminum because aluminum is light weight.

Wristband

In clinical work, wristband checking is one of the important ways of patient identification, and plays an important role in strict implementation of the checking system. Especially for severe patients, neonates and infants with surgery, coma, unconsciousness and disability, wristband should be worn as the basis for effective checking. And hospitalization number is the only sign that patients do not repeat!

In fact, medical wristband and other entertainment wristbands have certain differences. The main features are as follows: medical wristband can generally be waterproof, with one-time identification, and the greatest characteristics is the uniqueness. Medical wristband is anti-tear and non-destructive in principle. Medical wristbands can also be classified into handwritten type, printing type, RFID wristbands according to their working methods.

Main function of wristband

1 mark patient information

Doctors need to check the rooms. In the case of more patients, the information marked on the wristband can help recall the patient's illness condition assist in guiding the next step of treatment. Nurses need "three checks and seven pairs" in the process of dispensing drugs and injections. Among them, patients' names are checked to prevent misuse of drugs. For some sleeping or comatose patients, nurses can know the patient's name directly through the wristband.

2 Storage of information

The wristband has something like an electronic message strip, which can be used by patients in the process of payment, inquiry results, etc. There are many large hospitals where all terminals have been connected to the Internet, and patients only need to rely on the information strip on the wristband to quickly query the test results, hospitalization expenses and so on.

3 as a patient identity marker

Very few Alzheimer's patients occasionally get lost in the hospital. Others can use wristbands to find the patient's hospital bed number.

Classification of wristbands

First, wristband can be divided into adult medical wristband, child medical wristband and infant medical wristband according to the users.

1 Adult wristband

Suitable for adult wrist wear.

2 Marking patient information

The length of wristband is shorter than that of adult wristband, which is suitable for children to wear.

3 Infant wristband

The baby wristband is shorter in length, softer and milder in material, and suitable for infants to wear.

Second, according to the use form, it can be divided into handwritten medical wristband, printed medical wristband and RFID medical wristband.

1 Handwritten wristband

As the name implies, the wristband content is handwritten. This kind of wristband is convenient for people to fill in the content they want at will, and the efficiency is low.

2 Printing wristband

Printing medical wristband can be divided into thermal printing type and carbon belt printing type.

Printing is more convenient than handwriting. Especially in this efficiency-oriented era, patient information can be read only by scanning barcode, which reduces operation time and increases readability.

3 Medical RFID wristbands

The technology of RFID solution makes it possible to place a chip inside the RFID wristbands, which is similar to our bank card or bus card. They can read patient information through a simple scan without revealing it on the wristband surface. It can also encrypt the wristband information and fully guarantee the patient's privacy. It can also be read from a long distance, and can complete the work without touching the patient. But obviously the cost of this wristband is much higher.

What is the RFID tags?

Electronic product code is the development of global product code, which can identify targets beyond the horizon. Electronic product code is not just a radio bar code, but contains a series of data and information, such as origin, date code and other key supply information, which is stored in a small silicon chip. With tags, interpreters and connected computers, producers and retailers can know accurate product and inventory information at any time.

What's the price of the RFID tags?

The price of RFID tags varies from 30 cents to 50 dollars depending on the type of tags and application price. Generally speaking, smart tags used in high-end products are more than 50 cents, and active tags are much more expensive, and the price of complex sensitive components is more than 100 dollars.

Can RFID tags be used for metal objects? Can it be used for articles with high water content?

Yes. Radio waves are reflected back from metal objects and absorbed by water. This makes it difficult to track metal objects or objects with high water content. But well-designed systems can solve these problems.

How much information can RFID tags store?

Tags can store data ranging from 512 bytes to 4 megabytes depending on the type of business. The data stored in the label is determined by the application of the system and the corresponding standards. For example, labels can provide information about production, transportation and storage of products, as well as identification of the machines, animals and individuals. These are similar to information stored in barcodes. Labels can also be connected to databases to store product inventory number, current location, status, price, batch number information. Correspondingly, the RFID tag can directly determine the meaning of the code without referring to the database when reading the data.

Can RFID tags be connected to sensors?

Yes, the RFID tag has been connected to many sensors, including those that can record temperature and humidity. When environmental conditions change, labels can be prompted, especially when changes have an important impact on the storage and use of items.

What's the difference between transponder, smart tag and RFID tag?

At first, in the field of technology, transponder refers to the electronic module that can transmit information and reply information. In recent years, due to the rapid development of radio frequency technology, transponder has a new concept and meaning, also known as smart tag or tag. Intelligent tag is exactly an innovation of radio frequency tag, which consists of sticky tag and ultra-thin radio frequency tag. Intelligent tag combines the advantages of radio frequency technology and convenient and flexible tag printing. Intelligent tag with read and write function can be programmed many times, following the coding rules of the original tag production.

Which label is suitable for my customer's product?

Can labels work properly in water? Will metal destroy its function? What temperature does it work properly at? Products of higher water content, metal products, high or low temperatures can be a challenge to labeling. But carefully designed systems can overcome these shortcomings, so the types of tags are also very different according to the different application functions and objects. The purpose of RFID products is to use a unified standard of electronic product code so that products can be identified in different fields.

在美留学的高中生被开除的主要原因是违反校纪校规或者学术不诚实。中美的文化不同，导致很多很多高中生不了解美国方面的规定和法律，容易冲动行事造成不可挽回的开除后果。美国高中在做出开除决定以后，除非有很有利的证据，学生一般很难去申诉改变学校的判决。当高中生遭遇学校开除时，一定要立刻寻求帮助，保住合法的F1身份，紧急转学进入新学校。

　　那么美国高中紧急转学另一所私立高中需要哪些转学材料呢？下面就随求真教育小编一起来看看吧。

　　首先学生需要填写转学学校的申请表格，需要按照不同学校的表格来填写完成。

　　其次，学生还需要提交在原先学校的成绩单。一份优秀的成绩单对转入新学校更加有利。另外，学生还需要提交推荐信。一般都是由原先学校的授课老师提供。学校可以通过推荐信了解学生的学术能力。

　　下面这一项对于转学生来说就至关重要了——个人陈述。紧急转学的学生在撰写自己的个人陈述时，一定要巧妙的说明自己转学的原因，一方面要事实求是，另一方面一定要态度诚恳。

　　在陈述时一定要体现自己已经认识到了自己的不足，如果是因为和之前的寄宿家庭或是同学之间的矛盾有什么造成自己被误解的地方，也一定要在个人陈述中解释清楚，并告诉招生官自己在新的学校会如何去做，以避免之前的事情重演。

　　除此以外，有些高中还会要求学生提交补充材料（作品集、家长陈述等），部分学校还会要求学生面试。总的来说，虽然紧急转学的准备时间非常有限，但是同学们一定要认真准备转学材料，切不可马虎大意。
