Precision Steel Ball Bushing™ Bearing for end-supported linear motion, closed type, with a nominal bore diameter of 4.000 inches and a nominal length of 8.000 inches. The housing bore is sized 6.0010/6.0000 inches, with a recommended press fit of 6.0000/5.9988 inches. It has a dynamic load capacity of 5000 lbf and a mass of 20.20 lb. The bearing has six retaining grooves, a ball diameter of 6.0000/5.9988 inches, and uses a clearance fit of .0036C/.0004C. It is designed for use with a 4.0000/3.9980 inch shaft bore.
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.
