TSPB-8 is a closed-type Super Ball Bushing pillow block designed for end-supported applications with a 0.500 inch nominal bore diameter. It measures 2.00 inches in length, 1.69 inches in width, and 1.688 inches in height, with a 0.25 inch flange thickness. The unit features a 1/4-28 lubrication access and a 0.69 inch oil groove diameter, with a 0.84 inch bolt hole distance and 1.25 inch bolt hole diameter. It has a dynamic load capacity of 255 lbf and weighs 0.20 pounds, with a #6 bolt size for mounting. The unit is sealed at both ends and includes an A2 lubrication fitting compatible with sizes up to 0.500 inch 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.
