Contact Surfaces Treatment

By applying surface treatments on outer ring contact surfaces, it is possible to improve certain mechanical characteristics such as the hardness. By doing this, we can increase wear resistance while decreasing the friction coefficient. With certain treatments it is possible to achieve high resistance to specific chemical agents. The table below shows a small sample of examples of such surface treatments and their resulting technical characteristics.

Surface treatments on internal rolling parts such as balls, cages, and raceways can also be applied to increase the resistance to wear or the behavior of the bearings when lubrication is uncertain or intermittent. Some of these treatments even allow dry lubrication, for instance when oil or grease is not used at all.
