The company

The German company is specialized in special synthetic ball bearing manufacture, remarkably suitable for oxidative and corrosive environments.

HAKU is available to manufacture special ball bearing under specific customer request.

Synthetic Bearing

Plastic ball bearing is specifically useful when acids, solutions, corrosive substances in general and water can corrode a normal steel ball bearing.

Great chemical stability of plastic ball bearing allows a wide range of uses.

This kind of bearings are particularly suitable when watertight steel ball bearing can be damaged, increasing working risks.
