New Double Nut Ball Screw with Ball Retainer "SBKN Type"
Basic dynamic load is 1.8 times that of conventional models. Achieves long lifespan. DN value of 160,000. Supports high-speed operation. Low noise and long-term maintenance-free.
"Long Lifespan" The adoption of a double nut system has doubled the load capacity compared to a single nut system. "Achieving High-Speed Drive" With the newly developed end piece and R piece, we have achieved high-speed drive with a maximum DN value of 160,000 through an ideal circulation structure. "Smooth Movement" The use of a ball retainer eliminates collisions and mutual friction between the balls, resulting in minimal torque variation and achieving smooth and stable operation.

Detailed information
-
Supports longer lifespan and higher speed. Achieves approximately 6 times the lifespan of the single nut type and high-speed operation with a maximum DN value of 160,000.
-
Ideal ball circulation structure in the tangential direction Achieved an ideal circulation structure with newly developed end pieces and R pieces.
-
Smooth and stable operation Due to the ball retainer preventing collisions and mutual friction between the balls, torque fluctuations are minimal, allowing for smooth and stable operation.
