Product: Open Linear Bearing (LM10/12/13/16/20/25/30/35/40/50/60/80 OPUU; LME16/20 OPUU) What's included Package options: 1, 2, or 4 pieces of open linear bearing (select size from LM10, LM12, LM13, LM16, LM20, LM25, LM30, LM35, LM40, LM50, LM60, LM80 OPUU, and LME16/20 OPUU). Key benefits — why you need it Smooth, fast linear motion: Designed to minimize friction so moving parts run more quickly and with less resistance. Improved precision and repeatability: manufacturing accuracy helps maintain alignment and positional consistency in linear systems. Longer service life: Made from quality steel with fine workmanship to resist wear and extend operating life. Easy to integrate: Open design makes installation and maintenance straightforward on shafts and linear rails. Performance highlights Very low friction coefficient: The friction coefficient is onefiftieth of traditional sliding guidance, reducing energy loss and heat buildup. Low friction resistance and precision provide reliable, responsive motion for applications requiring accurate linear travel. Suitable for continuous or intermittent movement where low wear and smooth operation matter. Materials and construction Material: quality steel. Build quality: Precision machining and fine workmanship for consistent dimensions and durable surfaces. Compatibility and sizes Available sizes: LM10, LM12, LM13, LM16, LM20, LM25, LM30, LM35, LM40, LM50, LM60, LM80 OPUU; LME16/20 OPUU. Choose the size that matches your shaft or rail diameter for direct replacement or installations. Typical applications (use scenarios) CNC machines and routers: Improves axis accuracy and reduces heat and wear on linear axes. 3D printers and small automation equipment: Delivers smoother axis travel and better part quality at higher speeds. Industrial automation and pickandplace systems: Supports fast, repeatable linear motion with minimal maintenance. Notes for buyers Select the correct bearing size for your shaft or rail to ensure proper fit and performance. Package options allow a single replacement bearing or multiples for multiaxis systems. Reliable, lowfriction open linear bearings built for precision, long life, and straightforward integration in a wide range of linearmotion applications.
