Non Contact Rubber Sealed Ceramic Ball Bearings: Single row special application bearings, the outer and inner races are made from stainless steel and the rolling elements are made from Silicon Nitride (Si3N4) In addition to being excellent electrical insulators, ceramic bearings have a higher speed capacity and longer service life that normal steel only bearings. These bearings have a glass fibre reinforced cage (TN9). Non Contact rubber seals give the advantage of having a lower starting torque and rolling resistance in operation. This bearing is lubricated with MD Dry Film lubrication.
