Adjustment Linear Bearing LM-AJ

Adjustment Linear Bearing LM-AJ
ISUTAMI LM-AJ adjustment linear bearings, also known as LM-AJ adjustment linear ball bearings or LM-AJ adjustment linear bushing bearings. LM is the code name for the Asian metric series in linear bearings, and AJ is short for adjustment, it is mainly used in Asian markets like Japan, Korea, and Singapore,etc.

The material of LM-AJ adjustment linear bearing bushing and steel balls is high carbon bearing steel. The linear bushing is produced from a solid steel outer cylinder and incorporates an industrial strength resin retainer. The ball retainer is made of steel or synthetic resin POM. The retaining ring (usually represented by U or P) is made of NBR.

Adjustment Linear Bearing LM-AJ Features

The ball retainer is mounted inside the bushing together with the balls and sealed from one or both sides of the bushing with a sealing ring.
The outer bushing surface of LM-AJ adjustment linear bearing is completely seamless and has outer stop grooves near each end. LM-AJ Asian metric series linear bearings supplied by ISUTAMI:
The number of ball rows varies according to bearing size changes, ranging from 4-6 columns;
The inner diameter (dr) range is 6-60mm, and the inner diameter tolerance range varies with the inner diameter, which is mainly divided into -0.009~0mm, -0.009~0mm, -0.01~+0mm, -0.012~+0mm, -0.015~0mm;
The outer diameter (D) range is 12-90mm, and the outer diameter tolerance range varies with the outer diameter, which is mainly divided into -0.011~0mm, -0.011~0mm, -0.013~0mm, -0.016~0mm, -0.019~ 0mm, -0.022~0mm;
The length (L) range is 19-110mm, and the length tolerance range varies with length, and is mainly divided into two intervals of -0.2~0mm, -0.3~0mm;
The maximum radial eccentricity is divided into five grades of 0.012mm, 0.015mm, 0.02mm, 0.025mm;
The basic dynamic load rating (C) ranges from 21 to 480 kgf (basic rated life is 50 km);
The basic static load rating(Co) range is 27-1020kgf (basic rated life is 50km);
The date is consistent with KB-AJ standard bearings of the same specification.

LM standard linear bearings are generally mounted to SMA-AJ linear bearing pillow blocks with linear shafts.

Unlike normal ball bearings, the basic dynamic load rating of LM-AJ adjustment linear bearings is less than the basic static load rating, and as the size increases, this value gap increases significantly, up to 3 times the maximum.
