Precision ball bearings made of 440C stainless steel, designed for applications requiring low friction and corrosion resistance, are available in flanged styles with ABEC 5 or ABEC 7 tolerances. The S9912Y-E1850FS1 part corresponds to the 1850 bearing code, which has a 0.3125 inch bore, 0.5000 inch outer diameter, 0.1562 inch width, and 0.1960 inch flange width. It has a dynamic load rating of 149 lbf and a static load rating of 65 lbf, and is supplied with oil lubrication meeting MIL-PRF-6085. The bearing features a double shield (Fig. 3), providing added environmental protection. Dimensions and ratings are specific to the 1850 model in the 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.
