The BBXBLK-UFL21547 is a standard duty two-bolt flange mounting block with a 2-15/16 inch shaft bore, cast iron housing, and dual seal type, designed for set screw mounting. It measures 10-27/32 inches in height, 8-7/8 inches in length, 6-15/32 inches in width, and has a bolt circle diameter of 1 inch. The unit weighs 13.66 pounds and features a 7/8 inch bolt size with 29/32 inch flange thickness and 1-5/16 inch flange width. The product uses a 3/4 inch set screw for shaft retention and is rated for inch dimensions only.
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.
