The S99BP3MPB030830 is a self-lubricating, oil-impregnated plain bearing made from porous sintered bronze. It features an inner diameter of 3 mm, an outer diameter of 8 mm, and a width of 3 mm. This bearing is designed as an economical alternative to ball bearings and is dimensioned for interchangeability with comparable ball bearings. The outer diameter is concentric to the bore within 0.005 mm, and the faces are square to the bore within 0.008 mm, ensuring precise alignment and fit. The product is vacuum-impregnated with oil for lubrication, which enhances its performance in reducing friction and wear. Other bore and outer diameter sizes are available upon special order, making it a versatile option for various applications.
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.
