DMiotech 4 Pack LM12UU 12mmx21mmx30mm Linear Ball Bearings Bushing - High Precision for 3D Printers, CNC Machines, and DIY Robotics Projects

Function: Smooth movement, low friction, high rigidity. Linear bearing is a linear motion system for use with a cylindrical shaft with great stroke. Adavantage: The steel balls rotate with very little frictional resistance, which results in a smooth motion with high accuracy, low noise and long service life. A variety of models, bores and lengths are available. Application: Widely used in 3D printers, provide precise low friction linear movement.

APPLICATION Widely used in 3D printers, provide precise low friction linear movement.
