Bearing coating

A new and improved coating, SQ171E, protects bearings and components in applications including material handling, agricultural machinery, chemical and pharmaceutical industries, as well as compressors and pumps. The coating is thinner and provides longer-lasting protection against corrosion than its predecessor. The coating can be used for standard or special bearings as well as for all-metal parts that are exposed to wet or corrosive environments. Machined surfaces, such as races, can also be coated. The coating provides protection against water, condensation, and slightly alkaline or acidic cleaning agents. For more-effective protection, the coating also comes with a silicate-based sealing layer. Due to the reduced thickness of the coating (from 2 to 4 μm), coated and uncoated parts are completely interchangeable.
