The BBXBLK-HFL20720 is a standard duty, two-bolt flange mounting block with a cast iron housing and dual seal type, designed for locking collar applications with a 1-1/4 inch shaft bore. It features an eccentric collar for secure shaft retention and has a height of 6-11/32 inches, an overall length of 5-1/8 inches, and a width of 3-17/32 inches. The unit weighs 3.53 pounds and uses 3/8 inch fasteners. The mounting block supports shaft sizes from 1-1/4 inches up to 2-1/4 inches within its series and provides flange mounting for stable, rigid bearing 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.
