PULLEYS

Maxtran provides sheaves and pulleys specifically designed for v-belt-driven power transmission systems. The machined grooves of a v-belt pulley correspond to the profile of the appropriate v-belt size and style. Gray cast iron is carefully machined to create V-belt sheaves, which are subsequently painted and statically balanced. For multi-speed belt systems where torque and speed variations are necessary, variable pitch pulleys can be modified. Drive belt pulleys are available with a bushing mounted design or a fixed bore, also known as a completed bore, which has a predefined machined bore to standard shaft sizes and includes a standard keyway and 5/16-18 knurled setscrew for shaft locking. Maxtran offers bushing mounted pulleys in three different styles: Quick Detachable (QD), Taperlock (TL), and Double Split Tapered. We stock bushings with and without shaft keyways in thousands of bore sizes. For ease of identification and replacement ordering, all pulleys are numbered using industry-standard nomenclature. For instance, the pulley nomenclature 3B124SK is understood to mean the following: Our example would be 12.4" O.D., where 3 is the number of grooves, B is the type of belt, 124 is the outside pitch diameter in inches, and SK is the type of shaft bushing that must be ordered separately in order to mount to the pulley bore. Typical v-belt pulleys are available in variable speed sizes VL and VP, as well as A, B, C, 3V, 5V, and 8V. Every v-belt pulley that Maxtran supplies is made to either meet or surpass all ASTM/SAE requirements for gray iron casting. The most widely used mounting technique, regardless of the type of pulley, is to employ a bushing to latch onto the shaft.
