Pulley Wheel

Our pulleys use a Taperlock bush to adapt the bore down to a standard parallel shaft with keyway. The bush is mounted to the pulley using the the Taperlock bush, as you tighten the screws the bush gets compressed into the tapered pulley and clamps the shaft and key

Grooved Pulley

As the bearings in the pulley wear, you may begin to experience a high pitch squeaking or squealing. Over time this may result in complete bearing failure, causing the pulley to lock up and break the belt. Good used OEM idler pulleys are an economical replacement for excessivly worn components.

V-Belt Pulleys For Taper Bushes

A pulley, also called a sheave, is a mechanism composed of a wheel or shaft that may have a groove between two flanges around its circumference. A belt, or chain usually runs over the wheel and inside the groove, if present. Pulleys are used to change the direction of an applied force, transmit rotational motion, or realize a mechanical advantage in either a linear or rotational system of motion.

V Belt Step Pulley

V-belt pulleys (also called vee belt sheaves) are devices which transmit power between axles by the use of a v-belt, a mechanical linkage with a trapezoidal cross-section. Together these devices offer a high-speed power transmission solution that is resistant to slipping and misalignment.
