A 7Y55-FSS3118 is an ABEC 3, single-shielded, 440C stainless steel ball bearing with a 0.3125 inch bore and 0.625 inch outer diameter, rated for 48.0 lbf dynamic load and 17.60 lbf static load. It features a flanged design with a 0.1875 inch flange width and 0.359 inch outer width, and includes a double shield for contamination protection. Lubrication with MIL-PRF-6085A oil is specified for this variant.
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.
