Linear Motion Bearings <<Back
     
     
 

LM Series

 
 
     

Linear Bushing LM type is the unlimited stroke linear motion system with the LM shaft. Because of the point contact between Balls and LM shaft, minimum friction can be acquired and that can give you the high precision motion.

Linear Bushing aligns the balls toward the LM shaft by the single retainer and cylindrical shape of raceway. Outer sleeve is made of high-carbon chromium bearing steel, and inner and outer grinding processes are applied after heat treatment.

Interchangeability
The dimensions of Linear Bushing are standardized to have a full interchangeability. LM shaft is provided with the cylindrical grinding to have high precision fitting clearance.

Rigid Outer Sleeve
Hardened and precisely ground outer sleeve is made of bearing steel, and can be directly assembled with the needle bearing on outer surface.

High precision Retainer
The single body retainer guides 4~6 ball circuits, and it precisely guides the balls to moving direction with smooth motion.
