The LMK 40UU Linear Motion Bearing is a high-precision square flange linear ball bearing designed for smooth and stable linear motion on 40 mm hardened shafts. It is ideal for CNC machines, industrial automation systems, packaging equipment, printing machines, and heavy-duty linear motion applications where accurate, low-friction movement is essential.
The square flange design allows easy and secure mounting to machine frames or plates, providing strong support and precise alignment. The internal recirculating ball system ensures smooth sliding motion, reduced friction, high load capacity, and long service life.
Manufactured from premium hardened bearing steel, the LMK 40UU bearing offers excellent durability, corrosion resistance, and reliable performance even under heavy industrial use.
