The S9912Y-G1831FS2 is an ABEC 7 precision ball bearing made of 440C stainless steel, designed for low-friction rotational applications with oil lubrication per MIL-PRF-6085. It features a 0.1250 inch bore, 0.3750 inch outer diameter, and a flanged mounting style with a flange width of 0.023 inch. The bearing has a dynamic load rating of 81 lbf and a static load rating of 34 lbf, with double shielding as indicated by the FS2 suffix. Physical dimensions align with Fig. 3: width 0.3750 inch, land diameter inner 0.325 inch, land diameter outer 0.341 inch.
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.
