LM series linear motion ball bearings are designed for linear movement on hardened precision shafts. Recirculating steel balls reduce friction and support smooth, repeatable travel in compact motion systems.
Metric LM series bearings are widely used in automation equipment, machine tools, packaging machinery and general industrial linear-motion assemblies.
Key Advantages
1.Low-friction and smooth linear movement
2.Compact cylindrical design
3.Standardized dimensions for convenient replacement
4.Standard, adjustable and open-type designs available
5.Double seals and nickel-plated options available according to model
