The S99GSPM4062080 is a closed-series linear plastic bearing with a 40 mm bore, designed for maintenance-free, low-friction linear motion in corrosive or dirty environments. It features a polymer construction with an operating temperature range of -14°C to +90°C continuous, up to +120°C intermittently. The bearing requires a shaft with a hardness of at least HRC 50 and a surface finish of 8-16 RMS for optimal service life. It measures 80 mm in length, 62 mm in outer diameter, and supports a dynamic load capacity of 3999 N and a static load capacity of 27997 N. The bearing is secured by a retaining ring and weighs 334 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.
