This bronze Bunting Bearings powdered metal sleeve (plain) bearing is formed and sized to SAE (Society of Automotive Engineers) 841 specifications for supporting radial and axial loads. It has been sintered with powdered metals for strength, durability, and corrosion resistance, and it is vacuum-infused with SAE 30 oil, which remains in the pores of the bearing to provide lubricant from the bearing to the shaft during operation. This plain bearing has a maximum load value of 2,000 psi (pounds per square inch), a maximum velocity value of 1,200 sfpm (surface feet per minute), and a maximum load-at-velocity (PV) value of 50,000. It operates in temperatures ranging from 10 degrees F to 220 F (-12 degrees C to 104 C). Designed with a regular straight bore, this bearing fits to conventional cylindrical shafts. This oil-filled powdered metal sleeve (plain) bearing is for use in various applications such as heavy-lifting equipment, pumps, aircraft, and motors, among others.

Plain bearings (with no rolling elements) are used to handle radial or axial loads by providing a low-friction motion between two surfaces as shafts rotate or move back and forth through the center of the bearing. The most common types are bushings (also called bush), with a sleeve or flanged design, and are measured by their bore (inside diameter), outside diameter, length, and width (thickness). Plain bearings are used in automobiles, construction equipment, medical applications, railroad cars, turbines, various military applications, aeronautics, space exploration, among others.
