LMK20UU Square Flange Linear Ball Bearing – 1 Pc

The LMK20UU is a square-flange linear motion ball bearing designed to provide smooth and precise sliding along a 20 mm diameter hardened shaft. Its integrated square flange allows the bearing body to be easily mounted and secured on a flat surface or bracket, giving improved stability and alignment in machinery.

Inside the bearing shell are multiple rows of steel balls that recirculate, which reduce friction and enable consistent linear motion under load. The “UU” suffix indicates that it is sealed on both sides, helping prevent contamination and retaining lubricant for longer life.

With its 20 mm bore size, this bearing is suited for moderate to heavy duty applications in CNC machines, linear actuators, robotics, inspection systems, and other automation equipment where reliable, low-friction linear motion and secure flange mounting are needed.
