MRC released its High-Temperature Plane Bearing Inserts, which function at temperatures up to 500F. Three-part construction includes inner rings made of 316 stainless steel and outer rings made of 304 stainless steel. Both rings are anti-corrosive. A polymer sleeve is used to reduce friction and allow the bearing to operate at higher speeds. According to MRC, the polymer also replaces the need for lubrication and provides a nearly maintenance-free operation.
Diameters range from ĺ inch to 1 15/16 inch and an anti-rotation key slot in the outer sleeve mates with a set screw in the housing to prevent rotation. These bearings are also USDA-approved for contact with meat, poultry and dairy, either incidentally or directly.
