Engine Bearing Materials - Innovation & Performance
GP bearing has an extremely high load capacity (twice as high as conventional tri-metal bearing). GP material has good anti-friction properties due to the coined action of the proprietary overlay components. GP bearings have a higher maximum work temperature: over 500°F (compare with conventional tri-metal bearing with 350°F).
Plain bearing - Wikipedia
A simple linear bearing can be a pair of flat surfaces designed to allow motion; e.g., a drawer and the slides it rests on or the ways on the bed of a lathe . Plain bearings, in general, are the least expensive type of bearing. They are also compact and lightweight, and they have a high load-carrying capacity.
