A Harmonic Balancer is also known as a crankshaft pulley damper. It absorbs and dampens the torsional vibrations generated by the engine's rotating crankshaft. These vibrations are caused by the reciprocating motion of the pistons and can lead to excessive wear and tear.Attributes:• Allows the balancer to transmit power from the crankshaft to the fan• Manufactured to precise specifications and are built for durability and reliabilityApplications: A Harmonic Balancer is used in fan drives to reduce vibrations and maintain the stability of the engine.
