The S99GSPM1222032 is a closed-series linear plastic bearing with an 8 mm bore, designed for maintenance-free, self-lubricating operation in corrosive or dirty environments. It has a bore diameter of 12 mm, an outer diameter of 22 mm, and a length of 32 mm, with a groove depth of 1.3 mm and a groove width of 1.85 mm. The bearing supports a dynamic load capacity of 476 N and a static load capacity of 3558 N, and weighs 21 grams. It operates continuously from -14°C to +90°C, with intermittent exposure up to +120°C. It requires a shaft with a hard anodized aluminum finish of 8-16 RMS for optimal service life, and is secured by a retaining ring not included. The shaft tolerance for 12 mm bore is +0.075/+0.032 mm, and the outer diameter tolerance is 0/-0.021 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.
