TSSU-20-WW is a closed-type Super Smart Ball Bushing bearing designed for end-supported linear applications, featuring two integral wipers. It has a nominal bore diameter of 1.250 inches, a bearing length of 2.625 to 2.600 inches, and an outer diameter of 2.031 to 1.991 inches. The bearing mass is 0.52 pounds and it supports a dynamic load capacity of 2350 lbf. The recommended housing bore diameter ranges from 2.0008 to 2.0000 inches with a clearance of 0.0018C and preload of 0.0001P. The bearing contains 10 ball circuits.
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.
