S99GTPM202220 is a sleeve bearing made of T500® polymer, designed for low-friction rotation in high-temperature applications. It has a 20 mm bore, 22 mm outer diameter, and 20 mm length, with a bore tolerance of +0.104/+0.020 mm. The bearing operates from -100°C to +250°C and exhibits very low moisture absorption and universal chemical resistance. It is intended for press-fit installation in housings with a bore size of 22.021 to 22.000 mm and shafts sized 20.000 to 19.948 mm.
A bearing is a device that reduces friction between moving components by preventing metal-to-metal contact while assisting components (shafts, axles, and wheels) to freely rotate around a fixed axis, cutting down on heat generation and the amount of energy that is consumed. By replacing sliding motion with low-friction rolling motion, the life of the rotating components is increased. A bearing also keeps the shaft in the proper position, providing support and alignment and transferring the axial or radial loads to the housing.
The types of bearings that we offer include rolling element bearings, which consist of both ball bearings and roller bearings.
Balls are utilized as the rolling element in ball bearings; a retainer holds the balls in place and allows them to freely rotate. The balls are kept inside channels cut in both the inner and outer races. Because there is no surface contact between the balls and races, precision ball bearings have a lower load capacity for their size than other bearings.
