Surface coating

In agricultural engineering, radial insert ball bearings with Corrotect® coating offer a cost-effective alternative to bearings made of corrosion-resistant steel.
 

Coatings are considered design elements in the Schaeffler Group, which means they are already included in the first phase of product development. This means we ensure high quality and reliability for our products.

Corrotect® and Durotect® – Highly Effective in the Fight Against Corrosion.

Thin layers based on zinc-iron alloys have proven themselves in corrosion protection. The low layer thickness means that the raceways can also be coated without increasing internal clearance or losing preload. In agricultural engineering, radial insert ball bearings with Corrotect® coating offer a cost-effective alternative to bearings made of corrosion-resistant steel without having to accept the reductions in load carrying capacity associated with corrosion-resistant steel. The bearings remain protected against corrosion for a very long time. This increases the operating life of the housing units considerably.
