LMK40UU Square Flange Linear Ball Bearing – 1 Pc

The LMK40UU is a square-flange linear ball bearing designed to provide smooth and accurate linear motion along a 40 mm diameter shaft. The square flange mount simplifies installation by allowing the bearing body to be bolted securely to a flat surface, ensuring the bearing remains stable during operation.

Inside the bearing are hardened steel balls that circulate within the outer race, enabling low-friction sliding motion and good load distribution along the shaft. The sealed design (UU suffix) helps to retain lubrication and keep out contaminants for longer service life.

This bearing is well-suited for larger-scale linear motion systems found in CNC machines, heavy automation equipment, robotics, or any application where a 40 mm shaft is used and precise, stable movement is required.
