The TTWN-20 is a closed-type Super Ball Bushing twin pillow block designed for end-supported applications, with a 1.250 inch bore diameter and a weight of 3.75 lb. It features a 1/4-28 lubrication access and supports a dynamic load capacity of 3000 lbf. The block has overall dimensions of 4.00 inches in length, 3.00 inches in width, and 7.50 inches in height, with a 3.500 inch B dimension and a 2.50 inch H1 dimension. The base includes a #10 bolt hole for mounting.
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.
