The S99LBCM040080S is a closed-type linear ball bearing with a 40 mm bore, 60 mm outer diameter, and 80 mm length, designed for low-friction, high-precision linear motion. It features an AISI 52100 steel sleeve and balls with a Duracon M90 retainer, and includes seals at both ends. It has a dynamic load capacity of 2160 N and a static load capacity of 4020 N, with bore tolerance of 0/-0.012 mm, outer diameter tolerance of 0/-0.016 mm, and length tolerance of 0/-0.3 mm. The part is derived from the S99LBCM040080 series, with 'S' added for dual 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.
