  Wedge Pulley

  NBK

  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.
