Womala Crankshaft Timing Pulley OE 11237564969 Torsional Vibration Dampers for Bmw Auto Parts

The Torsional Vibration Damper (also referred to as the Crankshaft Timing Pulley, OE Number: 11237564969) is a critical component in BMW engines, designed to mitigate torsional vibrations generated by the crankshaft during operation.

Constructed from high-strength cast iron or steel with an integrated elastomeric (rubber) damping layer, this component combines rigidity with vibration-absorbing properties. The metal core ensures structural integrity to withstand high rotational speeds (up to 7,000 RPM), while the rubber layer dissipates vibrational energy—preventing excessive stress on the crankshaft, timing chain/belt, and other engine components.

• Vibration Reduction: Absorbs and dampens torsional oscillations from the crankshaft, reducing noise, vibration, and harshness (NVH) for smoother engine operation.
• Component Protection: Minimizes stress on the timing chain/belt, bearings, and crankshaft journals, extending their service life and reducing the risk of premature failure.
• Timing Precision: Maintains stable crankshaft rotation to preserve accurate timing between the crankshaft and camshafts, critical for optimal combustion efficiency and performance.
• Durability: Withstands extreme temperatures (-40°C to 150°C) and chemical exposure from engine oils, ensuring reliable performance over 100,000+ km of operation.

• We have 5 branches and deep cooperation with 50+ factories (including 5 joint-stock enterprises). 15,000㎡ production base, 10,000+ SKU inventory, to ensure timely delivery of orders.
• With 13 years of experience in Volvo accessories industry, we can provide accurate product matching and technical solutions. We provide one-stop procurement services to save customers' time and cost.
• We implement 10 strict quality inspection processes (such as noise detection, durability test, surface roughness test, etc.). The cooperative factories are supporting suppliers of international brands such as Bosch and Hella.
