High-speed, high power transmission V-belt pulley that conforms with JIS B 1855.
[Features]
· Consistent production from casting to machining and surface treatment.
· Cell production method allows the production of many kinds of products in low volume, with short lead times.
· Enables high speed and high power transmission to make it possible to design a system with a smaller pulley diameter, shorter shaft distance and fewer belts.
· Full lineup. 491 size. 3V: 153 size, 5V: 257 size, 8V: 81 size.
· 230 size has been added into JIS standard 261 size separately. Fine standardization of small-diameter sizes used particularly in drive side mechanisms.
· Top-quality pulley with materials, machining precision and balance accuracy exceeding JIS standards (JIS B 1855-1991, "Slim V-pulley").
· Imbalance tolerance on the outer circumference guaranteed to be 0.1% of pulley mass.
[Applications]
· Fans, etc.
Wedge pulley external appearance
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. 491 size
3V: 153 size, 5V: 257 size, 8V: 81 size. 230 size has been added into JIS standard 261 size separately. Fine standardization of small-diameter sizes used frequently in drive side mechanisms.
Moreover, the 3V ø56/60 (nominal size 56/60 mm), and 5V ø112/118/125/132/140 (nominal size 112/118/125/132/140) work with low edge cog type narrow width V belts
. Compared to regular lapped type belts, low edge cog type belts feature excellent flexibility and a high coefficient of friction. This improves transmission efficiency, and allows a smaller nominal size pulley to be used.
High quality exceeding JIS standards
The highest quality pulley, with materials, machining and balance accuracy exceeding JIS standards (JIS B1855-1991). Guaranteed imbalance tolerance on the outer circumference of 0.1% the pulley mass.
Product standard
Product standard conforms to JIS B1855-1991 "narrow width v pulleys"
Groove dimensions
The g dimension is set to 0.5 mm as shown in the Section A detail view. Years of research and testing have shown that this decreases wear and breakage, increasing belt service life. For this reason, the outer diameter of the wedge pulley is 1 mm larger
.

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."
Material/finish
