TAC High-precision Ball Screw Bearings with Double Seals

The TAC high-precision ball screw bearings with double seals produced by our factory have two structures, namely with built-in sealing rings and open types, for ball screw supports with strong axial stiffness. High-performance Krupp grease is sealed inside, eliminating the need for maintenance (as it can prevent external foreign matters from intruding). They possess excellent low starting torque and low rotational torque characteristics and are mainly used in working conditions that require precise axial positioning and repeat positioning accuracy.

Dentail

High axial stiffness: It firmly supports the ball screw, ensuring high-precision transmission even under the action of high-load axial forces, and guaranteeing the stability of the mechanical structure.
Low torque characteristics: During the starting moment and continuous rotation process, the torque requirement is extremely low, which is energy-efficient and puts little pressure on the driving motor and other power sources.
Excellent sealing: The double seal combined with high-quality grease prevents dust, water and impurities, extends the service life of the bearings and adapts to complex and harsh environments.
Maintenance-free: Thanks to the reliable seal and long-acting lubrication, daily maintenance procedures are reduced and the overall operating efficiency of the equipment is improved.
