The S99LBC-100156 is a closed-type linear ball bearing with a 1.0000 inch bore, 1.5625 inch outer diameter, and 2.2500 inch length. It features six ball circuits, AISI 52100 steel sleeves and balls, and a Duracon M90 retainer. The bearing has a dynamic load rating of 220 lbf and a static load rating of 353 lbf. Tolerances for bore, outer diameter, and length are specified as +.0000/-.00030, +.0000/-.00065, and +.000/-.012 respectively. It is designed for low friction, high positioning accuracy, and long travel life.
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.
