The S9912Y-E1238PS0 is a 440C stainless steel precision ball bearing, ABEC 5 grade, with a 0.1562 inch bore and 0.3125 inch outer diameter, single-shielded, and lubricated with oil per MIL-PRF-6085. It has a dynamic load rating of 73 lbf and a static load rating of 29 lbf, and is designed for applications requiring corrosion resistance and precise rotation. The bearing has a width of 0.1562 inches and uses a shield configuration that minimizes contamination while allowing for oil lubrication.
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.
