The S99GSPM2032045 is a closed-series linear plastic bearing with a 20 mm bore, designed for maintenance-free, self-lubricating operation in applications requiring corrosion and dirt resistance. It has an outer diameter of 32 mm and a length of 45 mm, with a tolerance of +0.092/+0.040 mm on the bore and 0/-0.021 mm on the outer diameter. The bearing supports a dynamic load capacity of 1121 N and a static load capacity of 7873 N, and is rated for continuous operation from -14°C to +90°C with intermittent exposure up to +120°C. It requires a shaft with an 8-16 RMS surface finish, typically hard anodized aluminum. The bearing is secured by a retaining ring and weighs 49 g.
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.
