TriStar RULON(R) 641 Sleeve Bearing 1"IDx1 1/4"ODx1 1/2" Length White Color DR6S-1620-12 (Pack of 2)

This TriStar white Rulon 641 plain sleeve bearing supports high radial loads. It is made of Rulon 641 polytetrafluoroethylene (PTFE) composite for resistance to chemicals, moisture, wear, and high temperatures. This bearing requires no lubrication, and is cleared by the U.S. Food and Drug Administration (FDA) for use in food and pharmaceutical applications. It has a maximum load value of 1,000 psi (pounds per square inch), a maximum velocity value of 400 sfpm (surface feet per minute), and a maximum pressure velocity (PV) value of 10,000. It operates over a temperature range of -400 to 550 degrees F (-240 to 288 degrees C). This sleeve bearing is for use in various applications such as automobiles, pumps, office machines, and home appliances, among others.Plain bearings provide low-friction sliding contact for relative motion between parts of a machine. They are the simplest type of bearing, with no rolling elements, and there are three basic types of plain bearings: radial plain bearings (also called sleeve bearings or bushings) to support rotating or reciprocating shafts, thrust bearings (also called washers) to support axial loads on shafts, and linear bearings to support and guide the motion of parts in a straight line. Flanged sleeve bearings have a flange on one end to support axial loads. Spherical plain bearings are radial bearings that allow for angular misalignment of the shaft. Plain bearings are made from durable, low-friction materials such as sintered or cast bronze alloys, plastic, or a combination of a metal shell and a plastic bearing surface. They can be lubricated externally or by a lubricant embedded in the bearing material. Plain bearings are used in automobiles, construction and mining equipment, textile manufacturing equipment, and robotics, among others.TriStar manufactures self-lubricating bearings and custom plastic components. The company, founded in 1982, is based in Shrewsbury, MA.
