LM20 UU FUZUKA

An LM20UU is a linear ball bearing designed for smooth linear (straight-line) motion along a shaft. It doesn’t rotate like a normal radial bearing — instead it slides along a straight 20 mm hardened shaft, guided by recirculating steel balls inside the bearing housing. This type of bearing is widely used in CNC machines, 3D printers, automation systems, robotics, and sliding mechanisms.
