High-speed ball screw with ball retainer, SBN type, small size
Ball screw SBN type with ball retainer now available in shaft diameters of 16 to 32 mm.
The SBN type high-speed ball screw with ball retainers eliminates collisions and mutual friction between the balls, and improves the retention of lubricants by installing ball retainers between the balls. This results in reduced noise, excellent torque characteristics, and long-term maintenance-free operation. The return piece creates an ideal circulation structure that scoops the balls in the tangential direction, enhancing the strength of the circulation section and achieving a permissible DN value of 130,000. (Note: DN value = ball center diameter × revolutions per minute) The preloading method adopts an offset preload method that shifts the lead at the center of the nut. As a result, the overall length of the nut is shorter and more compact compared to the double nut type. Additionally, as an option for long-term maintenance-free operation, a lubrication device for ball screws (QZ) developed for this purpose, as well as a wiper ring that prevents foreign matter from entering the inside of the nut even in harsh environments, have been standardized.
