The S9912Y-E0415PS0 is an ABEC 5 precision ball bearing made of 440C stainless steel, lubricated with oil meeting MIL-PRF-6085, and designed for low-friction rotation in mechanical systems. It has a bore diameter of 0.0469 inch, an outer diameter of 0.1562 inch, and a width of 0.0625 inch. The bearing has a dynamic load rating of 16 lbf and a static load rating of 5.1 lbf. It is unshielded, as indicated by the 'PS0' suffix corresponding to no shield in Fig. 1. The bearing's dimensional tolerances and load ratings are standardized for the ABEC 5 grade within this series.
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.
