The BPFWSS-4T is a four-piece precision spherical bearing with a 0.2500 in. bore diameter and 0.6250 in. outside diameter, designed for low-friction rotation in applications requiring stainless steel construction and self-lubricating performance. It features a bonded PTFE liner, 440C stainless steel races, and 17-4 PH heat-treated components. The bearing has a radial dynamic load rating of 5500 lbs, a static load rating of 1640 lbs, and a maximum oscillating load of 6505 lbs. It allows 14 degrees of misalignment and weighs 0.035 lbs. No-load breakaway torque ranges from 1.0 to 5.0 lb-in. The bore and outside 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.
