The crankshaft pulley is manufactured from forged ST52 carbon steel or GGG50 ductile iron. Its standard outer diameter ranges from 150 to 400 mm, depending on the engine. The part achieves dimensional stability through stress-relief heat treatment. Concentricity accuracy between the center bore and outer diameter is below 0.1 mm. The outer surface is machined to Ra 1.6 microns for V-ribbed or poly-V belt engagement. Its weight is between 2 and 10 kg, with static balance under 15 gram-centimeters. This component transmits belt drive tension forces up to 800 Newtons.
The pulley structure comprises a circular hub, a center bore, and often a multi-groove sheave. It attaches to the crankshaft via an H7/s6 interference fit, requiring a minimum press force of 5 tons. Some models feature internal splines or locking pins for torque transfer. The nominal transmitted torque varies from 200 to 1500 Nm. Modern designs integrate a rubber-metal vibration damper into the pulley assembly. This damper absorbs up to 70% of torsional vibrations. The design fatigue life exceeds 200 million load cycles.You can order and buy CRANK PULLY from Iran by contacting us through whatsaap and email.

Industrial Applications of the Crankshaft Pulley
This component plays a central role in simultaneous power transmission and timing synchronization. The crankshaft pulley is the primary driver of the engines timing belt or timing chain. It ensures precise coordination between piston and valve movement. In many designs, this pulley also drives the alternator and power steering pump belts. In advanced engines, the crankshaft position sensor is mounted on this pulley. It is made from high-precision cast iron or steel to resist wear. Its imbalance or wear can directly damage engine performance.
