MORIMOTO SEIMITSU SHAFT Co., Ltd List of Products and Services

Compared to conventional lead screws, the ball screw [MP series (accuracy grade: C3)] has an extremely high transmission efficiency, and the required torque is less than one-third.

Compared to conventional lead screws, it has an extremely high transmission efficiency, and the required torque is less than one-third. Ball screws [MG series (accuracy grade: C5) and ME series (accuracy grade: C7)].

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.

At Morimoto Precision Shaft Co., Ltd., we handle "Ball Screws." Due to advanced manufacturing technology and a strictly temperature-controlled factory, grinding and assembly inspections are conducted, ensuring high-precision and stable quality. Since the balls roll between the screw shaft and the nut, high efficiency is achieved, resulting in a driving torque that is less than one-third of that of conventional sliding screws. This allows for easy conversion of rotational motion to linear motion, as well as vice versa. 【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.
