The S99LBOM020045S is an open-type linear ball bearing with a 20 mm bore, designed for low-friction linear motion with high positioning accuracy and load capacity. It features a 4-circuit ball arrangement, a sleeve and balls made of AISI 52100 steel, and a Duracon M90 retainer. The bearing has an outer diameter of 32 mm, an overall length of 45 mm, and a width of 31.5 mm. It is rated for a dynamic load capacity of 862 N and a static load capacity of 1370 N. The bearing has a groove angle of 60° and includes seals at both ends, as indicated by the trailing 'S' in the catalog number.
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.
