JIS V-pulley Specification

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

Convenient additional machining service has been standardized.

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

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 Use V Pulleys." Imbalance tolerance on the outer circumference is 0.1% of the pulley mass.
Surface treatment, for improving corrosion resistance is a coating with 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."
