LM-LUU series linear bearings are long-type linear bearings designed for smooth and precise linear motion in industrial equipment, automation systems and mechanical assemblies. The extended bearing length provides greater support and stable guidance for linear motion applications.

Built with a durable outer shell and precision ball circulation structure, our LM-LUU linear bearings provide low friction, smooth movement and reliable running performance when used with linear shafts.

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