The S99LBCM008025S is a closed-type linear ball bearing with an 8 mm bore diameter, 15 mm outer diameter, 24 mm length, and 17.5 mm groove length, designed for low-friction linear motion with high positioning accuracy and load capacity. It features an AISI 52100 steel sleeve and balls with a Duracon M90 retainer, and includes seals at both ends. The bearing has a dynamic load capacity of 274 N and a static load capacity of 392 N. The part is identified as S99LBCM008025 with an added 'S' suffix for sealed ends, indicating a series variant with no other documented differences in specifications.
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.
