A 7B 4-SF202405 is an oil-impregnated bronze flanged bearing with a 0.626 inch bore, 0.753 inch outer diameter, and 0.625 inch length, designed for self-lubricating applications. The flange diameter is 0.815 inch and the flange width is 0.156 inch. The part is part of the S series of inch-sized sintered bearings with tolerances as specified: bore and outer diameter +0.000 / -0.001 inch, length ±0.005 inch, flange diameter ±0.005 inch up to 1.25 inch, and flange width ±0.0025 inch.
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.
