The S99LBOM030068S is a metric open-type linear ball bearing with a 30 mm bore, 47 mm outer diameter, and 68 mm length, designed for low-friction linear motion with high positioning accuracy and load capacity. It features five ball circuits with AISI 52100 steel sleeves and balls, and a Duracon M90 retainer. The bearing has a dynamic load capacity of 1570 N and a static load capacity of 2740 N, with a 50° contact angle and a 52.1 mm effective ball path width. The part includes seals at both ends, as indicated by the trailing "S" in the catalog number, which is added to the base model S99LBOM030068 to denote sealed construction.
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.
