PRODUCT DETAILS

KH series linear bearings feature a compact, slim design with optimized ball circulation structure, providing stable linear motion under small-to-medium loads. Compared with standard LM series, they offer higher space utilization and better rigidity in limited installation environments.
 
These bearings support high-speed linear movement, low friction and long service life, with standard metric dimensions for high interchangeability. They are widely applied in precision instruments, small automated machinery, medical devices and light industrial linear systems.
