The LMK 20UU Linear Motion Bearing is a high-performance square flange linear ball bearing designed for smooth and precise linear motion on 20 mm hardened shafts. It is commonly used in CNC machinery, industrial automation systems, packaging machines, printing equipment, and other linear motion applications where stable and low-friction movement is required.
The square flange design ensures easy installation and secure mounting to machine frames or plates, providing strong support and accurate alignment. The internal recirculating ball system allows the bearing to move smoothly along the shaft with minimal friction, ensuring high efficiency, reduced wear, and long service life.
Manufactured from premium hardened bearing steel, the LMK 20UU bearing offers excellent durability, corrosion resistance, and reliable performance even in demanding industrial environments.
