The SKF 6217C3SQ77 is a high-quality INSOCOAT deep groove ball bearing, specifically engineered with C3 radial internal clearance. This bearing features an electrically insulating coating on its outer ring, providing a minimum breakdown voltage of 1000 V DC. It is designed to prevent electrical erosion in applications where stray currents can damage standard bearings, ensuring enhanced reliability and extended service life in electric motors, generators, and other machinery. The deep groove design accommodates radial and axial loads in both directions.
