Abstract: A caster wheel assembly includes at least one hub that has an annularly dished concave region disposed between a pair of cylindrical lips about its outer periphery. An elastomeric tread has a convex inner periphery that seats in the concave region of the hub. The interface between the hub and tread is parabolic in cross-section to manage load-inducted stresses in the tread. The parabolic cross-section is defined by the equation y=A*x2, where A is between 1.5 and 4. A cylindrical lip/pad interface is established between hub and tread on opposite sides of the parabolic interface to accommodate high load situations. A bearing is supported in the hub, and a bushing inside the bearing. An axle shaft passing through the bushing attaches the hub and tread to a support bracket for use in a wide variety of industrial applications.

Abstract: In a method of inspecting a wheel hub unit configured by attaching a rolling bearing. Which has an inner ring and an outer ring, to a hub wheel, an acoustic inspection dement is arranged so as to be in contact with an outer peripheral face of the outer ring, and the wheel hub unit (components except the outer ring) is rotated to measure an acoustic value of the outer ring and hence conduct inspection. When the wheel hub unit (components except the outer ring) is rotated, a preloading load that is equal to or higher than a load at which an axial internal clearance of the rolling bearing is a negative clearance is applied to the rolling bearing, and the axial internal clearance of the rolling bearing A is changed from a positive clearance before application of the load to a negative clearance after application of the load.
