Super Standard Linear Bearing SLM

Super Standard Linear Bearing SLM
ISUTAMI SLM super standard linear bearings, also known as SLM super standard linear ball bearings or SLM super standard linear bushing bearings. S is the abbreviation of super. LM is the code name of the Asian standard series in linear bearings. It is suitable for Asian markets using metric units such as Japan, Korea, and Singapore.

SLM super standard linear bearing body is composed of POM resin holder, high carbon bearing steel balls and carbon steel ball plates. The sealing ring is on one side or both sides of the bushing (usually marked with P or U in the model), to fasten the seal.

Super Standard Linear Bearing SLM Features

The SLM super standard linear bearing has a ball row number range of 5-6 columns;
The inner diameter (dr) ranges from 16 to 50 mm;
The outer diameter (D) ranges from 28 to 80 mm;
The length (L) range is 37-100mm;
The basic dynamic load rating (C) ranges from 153-1169kgf, which is 2-3 times that of LM standard linear bearings;
The basic static load rating (Co) ranges from 128 to 810 kgf, which is basically the same as the LM standard linear bearing.

SLM super standard linear bearing can be replaced by LM standard linear bearing, generally mounted to SMA standard linear bearing pillow blocks, SMA-S short linear bearing pillow blocks, SMA-L long linear bearing pillow blocks, with the linear shaft of the corresponding diameter.

The basic dynamic load rating of SLM super standard linear bearings is greater than the basic static load rating, this is different from ordinary LM linear bearings, and the difference between the two loads varies significantly with size. In terms of weight, because the main structure uses POM engineering plastics, the weight is smaller than ordinary LM linear bearings of the same specification. Moreover, its moving life is 27 times that of ordinary LM series.

In addition, the ball plate of the SLM super standard linear bearing is convex, which can provide the pivot point in the center. The pivot point can automatically adjust the bearing by 1°. This performance can compensate the inaccurate machining of the base point, reduce the installation time as well as installation costs.

SLM super standard linear bearings can be used in high performance automation equipment, industrial robots, electrical equipment, measuring instruments, etc.
