S99GSP-125200263 is a closed-series linear plastic bearing with a 1.250 inch bore, designed for use with hard anodized aluminum shafting requiring an 8-16 RMS surface finish. It has an outer diameter of 2.000 inches, a length of 2.625 inches, and a groove width of 0.074 inches. The bearing supports a dynamic load rating of 595 lbf and a static load rating of 4163 lbf, with a weight of 0.18 lb. Operating temperatures range continuously from -58°F to +194°F, with intermittent exposure up to +248°F. It is maintenance-free, corrosion- and dirt-resistant, and secured by a retaining ring. The bore tolerance is +.0044/+.0020 inches, and the outer diameter tolerance is +.00000/-.00118 inches.
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.
