The BPFWSS-12T is a four-piece precision spherical bearing with a 0.7500 in. bore diameter and 1.3750 in. outer diameter, made of 440C stainless steel with a bonded PTFE liner for self-lubrication. It has a width of 0.875 in., a ball diameter of 0.845 in., and a misalignment angle of 13°. The bearing supports a static load rating of 37,000 lbs radial and 7,730 lbs axial, with a dynamic load limit of 26,200 lbs for oscillating motion. Its weight is 0.240 lbs, and the no-load breakaway torque ranges from 1.0 to 5.0 lb·in. The bore and outer diameter are concentric within 0.005 in. T.I.R.
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.
