The S99GSP-050088125 is a closed-series linear plastic bearing with a 0.500-inch bore, designed for use with hard anodized aluminum shafting featuring an 8-16 RMS surface finish. It measures 0.875 inches in outer diameter, 1.250 inches in length, and has a groove width of 0.052 inch. The bearing weighs 0.02 pound and supports a dynamic load rating of 80 lbf and a static load rating of 555 lbf. It is made of a self-lubricating polymer, operates continuously between -58°F and +194°F, and is secured by a retaining ring. The bore tolerance is +.0030/+.0013 inch. It is compatible with aluminum shafting and resists corrosion and dirt.
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.
