The BBXBLK-HFL21030 is a standard duty two-bolt flange mounting block with a cast iron housing and dual seal type, designed to support shafts up to 1-7/8 inches in diameter. It features an eccentric locking collar for secure shaft retention. The mounting block has a height of 7-3/4 inches, a bolt circle of 6-3/16 inches, and a total length of 4-7/32 inches, with a weight of 5.74 pounds. It uses 5/8-inch bolts and includes a two-bolt flange mounting style. The product is rated for inch-based shaft sizes and is intended for industrial bearing applications requiring robust, fixed shaft support.
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.
