Shock-absorbing pulleys for crankshafts
Choose Hutchinson quality, experts in high-grade anti-vibration systems
Damper pulleys are made up of a complex rubber-metal assembly that meets the demanding technical specifications of car manufacturers: vibration-absorbing properties and weight, balancing and lifetime specifications. Hutchinson expertise in anti-vibration parts is recognised worldwide and has enable the development of an extensive range of shock-absorbing pulleys for crankshafts. Hutchinson guarantees the best equivalent quality at origin by developing, testing and balancing each of the pulleys produced. The life of an engine may be shortened if the crankshaft pulley is poor quality.
Watch out for lowcost pulleys!
In the market, there are numerous copies that do not meet the manufacturers' stringent specifications. These copies may lead to a risk in terms of safety and engine lifetime. As in the images opposite, there are:
- Full metal pulleys: the rubber is only there for the sake of appearance on the outside (does not absorb the engine vibrations). Their weight exceeds the original specifications: the excess weight of the pulley inevitably leads to premature wear of the crankshaft bearings and the system of accessories (belts and rollers).
- Hollow pulleys: they do not perform any role of absorbing twisting and vibration of the crankshaft and lead to premature wear of the accessory belt. Discomfort, vibrations, failure and even breakage are all threats to your vehicle.
Balanced pulleys = safety
