The S99LBOM025058 is an open-type linear ball bearing with a 25 mm bore, 5 ball circuits, and a 40 mm outer diameter, designed for low-friction linear motion with high positioning accuracy and load capacity. It has a length of 58 mm, a retainer width of 44.1 mm, and a maximum outer diameter tolerance of 0/-0.011 mm. The bearing supports a dynamic load capacity of 980 N and a static load capacity of 1570 N, with a contact angle of 60°. The sleeve and balls are made of AISI 52100 steel, and the retainer is Duracon M90. No seals are present by default; adding an 'S' to the catalog number specifies sealed ends.
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.
