The slewing bearing is a new type of mechanical component. It has inner and outer rings, rolling elements, etc. The china slewing bearing is a large bearing capable of withstanding the combined load, and can withstand large axial, radial loads and overturning moments at the same time. The slewing bearing is widely used in the real industry. It is called "the joint of the machine", which is a mechanical device that needs to perform relative rotary motion between two objects, and also needs to bear axial force, radial force and tilting moment. Important transmission components required. With the rapid development of the machinery industry, slewing bearings have been widely used in marine equipment, engineering machinery, light industrial machinery, metallurgical machinery, medical machinery, industrial machinery and other industries.

According to the actual use and design structure have different working methods, there are two basic working methods:

the inner ring fixes its supporting role, the outer ring rotates

the outer ring fixes its supporting role, the inner ring rotates

ISUTAMI LM-L long linear bearings, also known as LM-L long linear ball bearings or LM-L long linear bushing bearings. LM is the code name for the Asian series in linear bearings, and L is the abbreviation for long. This type of bearing is mainly used in Asian markets where use metric units, such as Japan, Korea, and Singapore.

The bushing and steel balls of LM-L long linear bearing are made of high carbon bearing steel. The ball retainer is made of steel or synthetic resin POM material. The sealing ring, usually represented by U or P, is made of NBR.

Long Linear Bearing LM-L Features

The ball retainer is mounted inside the adjustable bushing together with the ball and sealed with a retaining ring (seal) from one side or both sides of the bushing to form linear bearings.

The bushing of LM-L long linear bearing is fully closed with an outer stop groove at each end. The number of ball rows of the LM-L Asian series linear bearings supplied by ISUTAMI varies according to the bearing size, ranging from 4-6 columns;

The inner diameter (dr) range is 6-60mm, and the inner diameter tolerance range varies with the inner diameter, and is mainly divided into four intervals of -0.01~0mm, -0.012~0mm, -0.015~0mm, -0.02~0mm;

The outer diameter (D) range is 12-90mm, and the outer diameter tolerance range varies with the outer diameter, which is mainly divided into -0.013~0mm, -0.016~0mm, -0.019~0mm, -0.022~0mm, -0.025~ 0mm five intervals;

The length (L) range is 35-209mm, and the length tolerance range varies with length, and is mainly divided into two intervals of -0.3~0mm and -0.4~0mm;

Themaximum radial eccentricity is divided into three grades of 0.015mm, 0.02mm and 0.025mm according to the bearing size;

The basic dynamic load rating (C) ranges from 43 to 770 kgf (basic rated life is 50 km);

The basic static load rating (Co) range is 54-2040kgf (basic rated life is 50km), which is twice that of LM standard bearings of the same specification.

LM-L long linear bearings are generally mounted to the corresponding extended linear bearing housings for use with linear shafts.

Unlike ordinary ball bearings, the basic dynamic load rating of LM-L long linear bearings is less than the basic static load rating, and this value can be expanded to nearly three times as the size increases.

Decomposition of each part of the linear bearing may result in the entry of foreign matter or adversely affect the assembly accuracy of each part. So do not disassemble.

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.
