Extended inner ring ball bearings with a 0.1875-inch bore and 0.375-inch outside diameter, double-shielded, and lubricated with MIL-PRF-23827C grease. The 3718 model has a dynamic load rating of 60.8 lbf and a static load rating of 24.8 lbf, with radial play tolerance of ±0.0002 to ±0.0005 inch. The bearing is constructed from 440C stainless steel and has a flanged outer ring. The physical dimensions include a width of 0.1875 inch, inner land diameter of 0.232 inch, and outer land diameter of 0.329 inch. All dimensions conform to ABEC 3 tolerance standards.
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.
