Rolled ball screw [MV series, MY series]

High transmission efficiency and low self-heating enable high-speed rotation! Maintains excellent durability.

The "rolled ball screw" maintains high precision and stable quality due to advanced manufacturing technology and rigorous temperature-controlled factory grinding and assembly inspections. Since the balls roll between the screw shaft and the nut, high efficiency is achieved, with driving torque being less than one-third compared to conventional sliding screws. Not only can it convert rotary motion into linear motion, but it can also easily convert linear motion into rotary motion. 【Features】 ■ Excellent durability ■ Capable of micro-feeding ■ High-speed operation possible ■ Easy maintenance ■ Wide variety *For more details, please refer to the PDF document or feel free to contact us.
