Hi-Ratio Series Pulleys

Model M-14 Adjustable Driver Pulleys - Imperial

(3)
Wide Variable Speed Belts

1/3 through 15 HP
      Pulleys in the WB series use wide variable speed belts for the most efficient transmission of torque through the widest possible speed range. These pulleys are two-side moveable for the best possible belt alignment when used with a grooved companion sheave. However, the location of the belt centerline close to the bore end of the pulley reduces the overhung load on motor bearings and seals. Precision-calibrated springs maintain correct pressure, keeping the belt properly tensioned and minimizing belt slip.

      WB pulleys can be used on both adjustable and fixed center drives. They offer maximum service when lubricated through a convenient grease ...
