The BPFWSS-3T is a four-piece, wide-series precision spherical bearing with a .1900 inch bore and .6250 inch outer diameter, constructed from heat-treated 440C stainless steel with a bonded PTFE liner for self-lubrication. It has a width of .437 inch, a ball diameter of .301 inch, and a ball flat of .531 inch with a minimum misalignment angle of 15 degrees. The bearing supports a static load rating of 2500 lbs and a dynamic load rating of 1770 lbs, with a maximum oscillating load limit of 4900 lbs and a weight of .031 lbs. The no-load breakaway torque ranges from .5 to 5.0 lb-in. The bore and outer diameter are concentric within .005 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.
