Description

Brand new 4″ outside diameter dual belt B section 2pc pulley assembly. This is a high quality cast iron pulley that has a 4″ outer diameter, is 1-3/4″ wide, and comes with a 1-1/8″ sheave to secure it to the motor shaft.

This is a easy to install pulley that comes with everything you need for a quick installation. You will receive (1) 4″ B Section Dual Belt Pulley, (1) 1-1/8″ Sheave, (1) Shaft Key, (2) Bolts w/ Lock Washers.

If your application only calls for a single belt pulley, you can just use one side of this pulley. Both grooves do NOT have to be used. Also, A Section belts can be used with this pulley; they just set a little deeper in the grooves, which will lessen the diameter by about 1/2″. Be sure to keep that in mind when calculating RPM.
