SKF 6213/HC5C3, Single row hybrid deep groove ball bearing, Open on both sides, 65 mm ID, 120 mm OD, 23 mm WD, Sheet metal Cage

Hybrid bearings have a ring made of bearing steel and a rolling element made of bearing-quality silicon nitride (Si3N4). Hybrid bearings are not only excellent electrical insulators, they are also approved for higher speeds and have significantly lower maintenance requirements than bearings manufactured entirely from steel. Silicon nitride has very good electrical insulation properties. This material protects the rings from damage due to electrical current and thus extends the life of the bearing.

• Predominantly used in small electric motors
• Bearing rings made of high-quality bearing steel, rolling element made of silicon nitride
• Excellent insulating properties
• Can prevent harmful current flow in the bearing
• Can significantly extend service life.
