The BPFWSS-7T is a four-piece wide-series precision spherical bearing with a 0.4375 in. bore, 0.9375 in. outer diameter, and 0.562 in. width, featuring a 440C stainless steel race, 17-4 PH heat-treated stainless steel liner, and a bonded PTFE lining for self-lubrication. It has a dynamic load rating of 20700 lbs. radial and 3650 lbs. axial, with a static load limit of 11750 lbs. and a maximum oscillating load of 18100 lbs. The bearing accommodates up to 10 degrees of angular misalignment, weighs 0.080 lbs., and maintains concentricity within 0.005 T.I.R. The bore torque range for sizes up to 0.7500 in. is 1.0 to 5.0 lbs.-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.
