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

A "gauge" is a measuring instrument used to inspect whether the dimensions being processed are within the allowable tolerance range. The usage is very simple; by passing the gauge through both the go side and the no-go side, it is possible to determine high-precision dimensions. Our company offers "limit gauges for screws" and "plug gauges." 【Features】 ■ High quality at about one-third the price of domestic products ■ Cost reduction possible as a "working gauge" for on-site inspections ■ Adopted by major companies *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.
