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 |
