A 7B 4-SF242806 is a flanged sintered bronze bearing with an inner diameter of 0.752 inch, an outer diameter of 0.878 inch, and a length of 0.75 inch. The bearing is oil-impregnated and self-lubricating, designed for low-friction rotary motion without external lubrication. The flange diameter is 1.128 inch and the flange width is 0.156 inch. Dimensions are toleranced per the series specification: bore and outer diameter have a tolerance of +0.000 / -0.001 inch, length tolerance is ±0.005 inch, and flange width is ±0.0025 inch. The outer diameter tolerance for sizes over 1-1/4 inch is ±0.0015 inch, though this part falls below that limit.
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.
