A 7B 4-SF061003 is a flanged sintered bronze bearing with a 0.189 inch inner diameter, 0.3145 inch outer diameter, and 0.375 inch length, featuring a flange diameter of 0.315 inch and flange width of 0.0625 inch. It is oil-impregnated and self-lubricating, designed for low-friction rotary applications. The part is specified with tolerances of +0.000 / -0.001 inch for bore and outer diameter, ±0.005 inch for length and flange diameter, and ±0.0025 inch for flange width.
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.
