A 7B 4-SP263410 is an oil-impregnated bronze plain bearing with an internal diameter of 0.815 inches, an outer diameter of 1.065 inches, and a length of 1.25 inches. It is self-lubricating and designed for applications requiring low friction without external lubrication. The bearing has a length tolerance of ±0.0050 inches, consistent with all parts in the S series up to and including 1-1/2 inches in length. The internal and external diameter tolerances for parts up to 2-1/2 inches are +.0000 / -.0015 inches. The part is made with sintered bronze and adheres to the dimensional specifications and tolerances defined in the S series for inch-sized components.
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.
