A metric open-type linear ball bearing with a 25 mm bore, five ball circuits, and sealed ends at both sides, designed for low-friction linear motion with high positioning accuracy and load capacity. It has an outer diameter of 40 mm, an overall length of 58 mm, and a seal width of 12.5 mm. The bearing uses AISI 52100 steel balls and sleeve with a Duracon M90 retainer. It supports a dynamic load rating of 980 N and a static load rating of 1570 N. The cage angle is 60°, and the dimensional tolerances follow the specified metric ranges for bore, outer diameter, length, and seal width.
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.
