An extended inner ring ball bearing with a 0.1875 in bore and 0.5 in outer diameter, designed for low-friction rotation and load support in precision applications. It has a double shield (ESS) and is lubricated with oil meeting MIL-PRF-6085. The bearing is made of 440C stainless steel, has an ABEC 3 tolerance grade, and is rated for a dynamic load of 140 lbf and a static load of 59 lbf. The width is 0.1960 in, with inner and outer land diameters of 0.2272 in and 0.2272 in respectively. The package is unmounted and intended for standard industrial mounting.
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.
