About Single-Groove V-Belt Pulleys

These V-belt pulleys have a single groove that accepts a compatible single V-belt to provide maximum friction and torque in a compatible V-belt drive system. When matching a belt to a pulley, make sure the style (or series) and width of the belt are compatible with the pulley.

Choose these durable cast iron pulleys for good strength in a range of applications.
