The S99LBC-038063S is a closed-type linear ball bearing with a 0.3750 inch bore, 0.6250 inch outer diameter, and 0.8750 inch length, designed for low-friction, high-accuracy linear motion. It has four ball circuits, with ball groove diameter of 0.6358 inch and groove width of 0.5880 inch. The bearing features an AISI 52100 steel sleeve and balls with a Duracon M90 retainer, and includes seals at both ends, as indicated by the trailing "S" in the part number. Dynamic load rating is 51 lbf and static load rating is 71 lbf. Bore tolerance is +.0000/-.00025 inch, outer diameter tolerance is +.0000/-.00050 inch, and length tolerance is +.000/-.012 inch.
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.
