KF has developed a modular corrosion protection solution to protect the wheel bearing against corrosion.
The anti-corrosion coating for the hub bearing unit makes the disassembly of the bearing from the knuckle and rim easier. It improves the aesthetics of the bearing during the vehicle life and helps maintain the effectiveness of the seals by preventing them from coming into contact with rusty surfaces.
The anti-corrosion coating feature has been designed to withstand over 400 hours of salt-spray test (DIN EN ISO 9227 NSS) without jeopardizing the geometrical tolerances of the hub-bearing unit.
This anti-corrosion coating can be applied to all flanged hub bearings units of second and third generation and has scalable layer thickness. It comes with a low thickness tolerance and has a maximum working temperature above 200°C.
The anti-corrosion hub-bearing unit offers a strong resistance against corrosion. It also provides a high flexibility in selecting the area of the bearing to be protected. It is eco-friendly and uses a water-based paint. It is suitable for both new designs and retrofit.
