JIS V-Pulley, D Type

JIS V-Pulley, D Type

Full lineup of V-belt pulleys that conform to JIS B 1854.
[Features]
· Consistent production from casting to machining and surface treatment.
· Shaft hole, keyway and push screw machining standardized.
· Cell production method allows the production of many kinds of products in low volume, with short lead times.
· 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 (JISB1854-1987, "General use V-pulley").
· Imbalance tolerance on outer circumference is 0.1% of pulley mass.
· Surface treatment uses electrodeposition coating for improved rust resistance and a beautiful finish.
[Applications]
· Fans, etc.

Outer circumference / rim side vibration tolerance value and outer diameter tolerance value (units: mm)
Parentheses enclose JIS B1854-1987 value.

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
Main body: FC200 or higher coating (NBK blue)

Convenient additional machining service 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 the JIS standard
Top quality pulley with materials, machining and balance accuracy exceeding JIS standards (JIS B1854 - 1987 "General Use 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.
