DLC Coated Ball Bearings

DLC Coated Ball Bearings are constructed from 440 stainless steel and coated with a thin layer of carbon coating.  This process adds considerable corrosion resistance beyond what traditional 440 material will protect against.  These bearings can be manufactured in any size and configuration to fit your demanding application.  Ideal applications include salt water environments as well as laboratory and flow meter type applications.  Customers are advised to tested the bearings in actual conditions to validate improvements offered for those specific conditions.

DLC Coated Ball Bearings are currently available in the sizes listed below, however APT Bearing can work with you for prototypes for your unique OEM application.  Contact a bearing specialist if you’d like to learn more about these products or other solutions we can assist you with.
