The S9912Y-G3150PS1M is an ABEC 5 precision ball bearing made of 440C stainless steel, with a 0.3125 inch bore and 0.5000 inch outer diameter, designed for low-friction rotation in light-load applications. It features a single shield and is pre-lubricated with MIL-PRF-23827C grease. The bearing has a dynamic load rating of 62 lbf and a static load rating of 31 lbf, with radial play tolerance of ±0.0002 inch. The overall width is 0.1562 inch, and the land diameters are for reference only. The design supports shielded operation with sealed 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.
