Precision ball bearings made of 440C stainless steel are designed for low-friction rotation in applications requiring corrosion resistance and standard load capacity. The series includes flanged bearings with bore diameters from 0.0469 inch to 0.875 inch and outer diameters up to 0.969 inch, with dynamic load ratings ranging from 16 lbf to 569 lbf and static load ratings from 5 lbf to 273 lbf. Bearings are available in three shield configurations: no shield, single shield, or double shield, with radial play tolerances of ±0.0002 inch or ±0.0005 inch. Lubrication options include oil meeting MIL-PRF-6085 or grease meeting MIL-PRF-23827C, with ABEC 5 and ABEC 7 accuracy grades specified across 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.
