The BPFFKS-070 is a two-piece heavy-duty spherical bearing with a 0.4375 in. bore and 0.9062 in. outer diameter, constructed from alloy steel with a heat-treated outer race and chrome-plated ball. It has a static load rating of 22,300 lbs. and a maximum width of 0.437 in. The bearing features a metal-to-metal contact design with a lubrication hole and groove, and includes a chamfer of 0.015 in. The product is available in a self-lubricating variant by appending "T" to the catalog number, though this version omits lubrication features.
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.
