💡 What is a linear bushing used for in a linear slide unit application? Linear bushings let shafts slide smoothly and support radial loads in linear slide units. - They provide low-friction support on 12 mm shafts for CNC tables, 3D printers, and automation equipment, working with linear slide units and guide rails. - Open bushings are handy when you need debris clearance or easy lubrication access; sealed ball bearing or ceramic options suit dirty or high-speed environments. - Choose by load and shaft size: this unit offers dynamic 298 N and static 711 N, so match to your linear slide unit or bearing system requirements.
