High-speed ball screw with ball retainer, SBK type, large lead series
Achieved a DN value of 210,000 (realizing a maximum feed speed of 200 m/min).
The SBK type high-speed ball screw with ball retainers is a large lead ball screw designed to eliminate collisions and mutual friction between balls, thereby improving grease retention. As a result, it achieves low noise, high speed, and long-term maintenance-free operation. Furthermore, the ideal circulation structure that scoops the balls in the tangential direction (see Figure 2) enables high-speed use at a DN value of 210,000. (*DN value = ball center diameter × revolutions per minute)
