The TTWN-8 is a closed-type Super Ball Bushing twin pillow block for end-supported applications, with a nominal bore diameter of 0.500 inch. It measures 2.00 inches in length, 1.38 inches in width, and 3.50 inches in height. The block has a dynamic load capacity of 510 lbf, a mass of 1.25 lb, and uses a #6 bolt for mounting. Lubrication access is provided via an oil fitting. The unit features seals at both ends and is designed for applications requiring extended travel life, as indicated by its position on the rated life chart.
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.
