Bearings protect against current damage

Inscoat electrically insulated rolling bearings protect against potential damage caused by the passage of electric current in ac and dc motors, generators, and associated equipment.

Inscoat electrically insulated rolling bearings protect against potential damage caused by the passage of electric current in ac and dc motors, generators, and associated equipment. Electrical insulation function is integrated into the bearing. Products have a thin aluminum oxide layer that forms a barrier against electric arcing that can cause fluting damage to rollers and raceways or grease oxidation. Bearings have been performance-tested to 1,000 V dc with a minimum 50 M ohms resistance. Bearing boundary dimensions conform to ISO and ABMA standards and can replace non-insulated bearings without requiring design changes in an application or rework prior to normal mounting. www.skfusa.com , SKF USA Inc.
