The S99GLPM203245 is a closed-series linear plain bearing with a 20 mm bore, designed for maintenance-free operation with hard anodized aluminum shafts. It has a metal body with an anodized aluminum housing and a J® Polymer liner, offering corrosion and dirt resistance. The bearing is rated for continuous operation between -14°C and +90°C, with intermittent use up to +120°C. It is compatible with shaft surface finishes of 8-16 RMS and uses an MD0471MQB032 retaining ring. Dynamic load capacity is 2251 N, and static load capacity is 15751 N. The overall length is 45 mm, and the groove depth is 31.2 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.
