The S99GLPM406280 is a closed-series linear plain bearing with a 40 mm bore diameter and an overall length of 80 mm, designed for maintenance-free operation with a J® Polymer liner and anodized aluminum body. It is rated for a dynamic load capacity of 7998 N and a static load capacity of 55998 N, and requires a shaft with an 8-16 RMS surface finish, such as hard anodized aluminum. The bearing operates continuously between -14°C and +90°C, with intermittent capability up to +120°C. Recommended retaining rings are specified as MD0471MQB062.
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.
