Abstract
A mounting for the road wheel of an automotive vehicle includes a spindle, a hub located around the spindle and inboard and outboard tapered roller bearings located between the hub and spindle where they are mounted in opposition. The cones (inner races) of the two bearings are separated by a spacer which at its ends is attached to the cones. The spacer holds the cones together within the hub so that the bearings and hub can be installed on and removed from the spindle as a unit. The spacer also establishes the setting for the bearings. In addition, the mounting has a seal located in the inboard end of the hub. The seal has lips which establish dynamic fluid barriers along the cone of the inboard bearing and along an adjacent sealing surface on the spindle without contacting the cone or spindle. The raceways and rollers for the two bearings have highly crowned profiles and the hub and the seal within contain an optimum amount of grease for lubricating the bearings.
