The S99LBCM025058 is a metric closed-type linear ball bearing with a 25 mm bore, 40 mm outer diameter, 59 mm length, and 6 ball circuits. It features a sleeve and balls made of AISI 52100 steel and a Duracon M90 retainer. The bearing has a dynamic load capacity of 980 N and a static load capacity of 1570 N, with a groove width of 38 mm and a groove diameter of 76.5 mm. It is designed for high positioning accuracy, high load capacity, and quiet movement with long travel life. The part is not available with seals.
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.
