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 ¾ 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.
Producing high-quality end-production metal parts with additive manufacturing for applications like aerospace and medical requires very tightly controlled processes and materials. New standards and guidelines for machines and processes, materials, and printed parts are underway from bodies such as ASTM International.
Engineers at the University of San Diego’s Jacobs School of Engineering have designed biobatteries on commercial tattoo paper, with an anode and cathode screen-printed on and modified to harvest energy from lactate in a person’s sweat.
