LM series linear bearings are designed for smooth and precise linear motion in industrial equipment, automation systems and mechanical assemblies. They provide stable guidance with low friction and reliable running performance.

Made with a durable outer shell and precision ball circulation structure, our LM linear bearings offer good wear resistance, smooth movement and consistent performance when used with linear shafts.

We manufacture LM series linear bearings in a wide range of bore sizes and dimensions. Standard sizes, OEM requirements and bulk orders are available directly from our factory.
