The BBXBLK-HFL21135 is a standard duty, two-bolt flange mounting block with a cast iron housing and dual seal type, designed to support shafts up to 2-3/16 inches in diameter using an eccentric locking collar. The unit measures 8-13/16 inches in height, 7-1/4 inches in width, and 5-1/8 inches in depth, with a total weight of 8.38 pounds. It features a 5/8 inch bolt size and 23/32 inch collar width, compatible with standard flange mounting configurations. This part is part of a series where all variants share the same housing and mounting design, with dimensional variations based on shaft size.
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.
