Description
SC 25 UU Linear Motion Bearing Unit
The SC 25 UU is a compact linear motion bearing unit that houses a 25 mm inner diameter linear ball bearing within a durable metal or aluminum housing. It is designed to provide smooth, low-friction linear movement along a cylindrical shaft, making it ideal for CNC machines, 3D printers, automation systems, robotics, and other mechanical equipment where precise straight-line motion is important. The “UU” designation indicates that the bearing is sealed on both sides, protecting the internal balls from dust and contaminants, which enhances durability and reduces maintenance. Its robust design ensures high rigidity, long service life, and reliable performance in various industrial applications.
