Linear bearing is a low-cost production of linear motion system for unlimited travel in conjunction with the cylinder axis. Because of point contact between ball and straight axis, so the load is small. The ball is spinning with the smallest friction, it can run a high precision and smooth motion.

Application

It is widely used in linear motion system. Such as, punch, tool grinding machine, automatic cutting machine, printer, card sorting machine, food Packing Machine, other sliding parts on industrial machinery.
