The S99LBC-050088 is a closed-type linear ball bearing with a 0.5000 inch bore, 0.8750 inch outer diameter, 1.2500 inch length, and four ball circuits. It features an AISI 52100 steel sleeve and balls with a Duracon M90 retainer, offering high positioning accuracy, high load capacity, and quiet movement. The bearing has a dynamic load rating of 115 lbf and a static load rating of 176 lbf. Tolerances for bore, outer diameter, length, and groove dimensions are specified as +.0000/-.00025, +.0000/-.00045, +.000/-.008, and +.000/-.008 respectively.
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.
