The BPFWSS-5T is a four-piece precision spherical bearing with a 0.3125 in. bore diameter and 0.6875 in. outside diameter, designed for low-friction oscillating motion. It features 440C stainless steel races, a heat-treated 17-4 PH stainless steel liner, and a bonded PTFE fabric liner for self-lubrication. The bearing has a width of 0.437 in., a ball diameter of 0.360 in., and a maximum angular misalignment of 14 degrees. It supports a dynamic radial load rating of 9400 lbs, a static radial load rating of 1640 lbs, and a dynamic axial load limit of 6505 lbs. The weight is 0.035 lbs. Bore diameter and outside diameter are concentric within 0.005 in. T.I.R. The no-load breakaway torque ranges from 1.0 to 5.0 lb-in.
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.
