The S99LBC-050088S is a closed-type linear ball bearing with a 0.5000 inch bore, 0.8750 inch outside diameter, and 1.2500 inch length, designed for low-friction, high-accuracy linear motion. It features four ball circuits, with ball groove diameter of 0.9625 inch and groove width of 0.0459 inch. The bearing has a dynamic load rating of 115 lbf and a static load rating of 176 lbf. The sleeve and balls are made of AISI 52100 steel, and the retainer is Duracon M90. The part includes seals at both ends, as indicated by the trailing "S" in the catalog number. Physical tolerances are specified as bore +.0000/-.00025 inch, outside diameter +.0000/-.00045 inch, and length +.000/-.008 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.
