LM Linear Motion Bearings

LM series linear ball bearings for shaft-guided low-friction linear motion.

LM linear bearing principle

LM linear ball bearings (linear bushings) run on hardened precision shafts with recirculating ball paths. They provide economical linear guidance for automation, packaging, medical equipment and general machinery where profile rail systems are not required.

Catalogue status

LM size codes (e.g. LM6 to LM80) are industry-standard designations across multiple manufacturers. Golden Bearing Company confirms supply against verified stock and manufacturer data on enquiry.

Selection notes

Shaft hardness

Shaft raceway hardness and surface finish strongly affect life and friction.

Support spacing

Shaft deflection limits accuracy; use adequate shaft diameter and support spacing.

Sealing

Open, sealed and adjustable variants exist across manufacturers.
