Precision Steel Ball Bushing™ Bearings (Closed Type) for end-supported applications, with a nominal bore diameter of 3.000 inches and a nominal length of 6.000 inches, and a dynamic load capacity of 2600 lbf. The bearing has a housing bore range of 4.5010 to 4.5000 inches, a retainer groove distance of 0.120 inches, and six balls. It uses a clearance fit of .0026C or preload of .0005C. The bearing mass is 9.50 pounds. The part is designed for use with a linear race and requires a recommended housing bore fit of 4.5000/4.4988 inches.
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.
