basic information
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 pipe 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 employs an offset preload system that shifts the lead at the center of the nut. This makes the overall length of the nut shorter and more compact compared to the double nut type with shim preload. Additionally, as an option for long-term maintenance-free operation, a lubrication device for ball screws, QZ, has been developed, along with a wiper ring that prevents foreign substances from entering the inside of the nut even in harsh environments, which is now standardized.
