Mechanidrive offers pulleys and sheaves for running drive belts in all power transmission systems. A V-Belt Pulley has machined grooves that match the profile of the applicable v-belt style and size. V-belt sheaves are precisely machined from gray cast iron, painted and then statically balanced. Timing Belt Pulleys are a of synchronous drive pulley with machined teeth matching the tooth profile of the applicable pitch belts. Variable Pitch Pulleys can be adjusted for multi-speed belt systems where changes in speed and torque are required. Each drive belt pulley is furnished in either a stock bore, also called a plain bore with no keyway or setscrew, in QD Flange style or Taperlock bushing style where you will need a Shaft Bushing to mount the pulley or a machine finished bore with standard keyway and a 5/16-18 knurled setscrew for shaft locking. Regardless of the pulley the use of Shaft Pulley Bushings to lock onto the shaft is the most commonly utilized mounting method. Mechandrive sells a complete line of QD bushings(Quick Disconnect), TL bushings(Taperlock) and Double Split Taper Bushings(H, P, Q styles) where there is a double face split for greater pressure onto the shaft. Our bushings are stocked in thousands of stock bore and finish bore sizes both with and without shaft keyways.
