How does the pulley protect the alternator?

It prevents backspin and reduces mechanical stress on bearings and windings, lowering replacement costs by 30-40%.

What materials are used in the construction?

The outer pulley uses heat-treated steel or aluminum alloy, while seals are made of Nitrile rubber or FKM.

What testing standards does the product meet?

It undergoes 500-hour cyclic load tests and complies with ISO 9001 and REACH standards.
