Features

We deliver even single unit orders quickly

Consistent production from casting to machining and surface treatment. Additionally, we have developed NC machinery, automatic machinery, balancers, etc. specifically for pulley machining. Cell production allows the production of many kinds of products in low volume, with short lead times.

Convenient additional machining service has been standardized

Shaft hole, keyway, and set screw machining are available in standardized form. Easy set-up.

Extensive product range. 650 size

A: 146 size, B: 218 size, C: 212 size, D: 74 size. The 369 size has been added into JIS standard 281 size separately. Fine standardization of small-diameter sizes used frequently in drive side mechanisms.

High quality exceeding JIS standards

Top quality pulley with materials, machining and balance accuracy exceeding JIS standards (JIS B1854 - 1987 "General Used V-Pulleys." Guaranteed imbalance tolerance on the outer circumference of 0.1% the pulley mass. Surface treated with a coating to improve corrosion resistance and provide a beautiful finish.

Balance

Imbalance mass allowance on the outer circumference is 0.1% or 1 g of the pulley mass, whichever is larger. At a circumferential speed of 15 m/s, this corresponds to G16 of the JIS B 0905 "Rotating Machines - Balance Quality of Rigid Rotors."
