Industrial Alternator Pulley

We are manufacturer of alternator pulley. An alternator pulley is used to smooth out irregularities of driving speed of an automobile alternator. During normal operation alternator pulleys can rotate at up to 18,000rpm and coupled with rapid acceleration and deceleration can lead to premature alternator, pulley and drive belt failure. To prevent this Overrunning Alternator Pulleys (OAPs) were developed that are designed to decouple the alternator from the rotational irregularities of the crankshaft in an internal combustion engine, as the alternator has the highest moment of inertia in the accessory belt drive.
