The S99GSPM5075100 is a closed-series linear plastic bearing with a 50 mm bore and 75 mm outer diameter, designed for maintenance-free, corrosion-resistant operation with hard anodized aluminum shafts. It measures 100 mm in length and is secured by a retaining ring. The bearing supports a dynamic load capacity of 6250 N and a static load capacity of 43748 N, with a weight of 579 g. It operates continuously from -14°C to +90°C and intermittently up to +120°C. Shaft surface finish must be 8-16 RMS for optimal service life.
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.
