NoWear Bearings

NoWear is a wear-resistant carbon coating that can be applied to the rolling elements and inner ring raceway(s) of a bearing (designation suffix L7DA) or only the rolling elements (designation suffix L5DA) ().A physical vapour deposition process applies the wear-resistant carbon coating ranging from 1 to 3 μm depending on the size of the bearing. The hardness of the coating is 1 200 HV10.
