Crankshaft Pulley:

Engineering & B2B Sourcing Guide for Crankshaft Pulley

Crankshaft pulleys transmit accessory-drive torque while controlling torsional vibration generated by combustion and crankshaft speed fluctuation. For B2B programs, the correct design must match the engine order, belt layout, mounting interface and expected service environment.

AuraMaia supports elastomer and tuned crankshaft-pulley programs from drawing review through dynamic validation. Buyers can define OE references, dimensional tolerances, rubber formulation, balance grade and production approval requirements.

Crankshaft Pulley Selection Guide

Parameter	Standard Duty	Severe Duty	Sourcing Check
Damping range	Tuned engine order	Wider transient range	Confirm speed and load profile
Elastomer	NR / SBR	HNBR or project-specific	Confirm temperature and fluid exposure
Balance quality	Application defined	Tighter high-speed target	Specify test speed and standard
Interface	OE drawing	Customized geometry	Verify bore, keyway and belt alignment
