A wheel balancer has a support by which a wheel may be rotatably held by bearing units to be free to turn until it comes to rest with its heavy point lowermost. The wheel supporting shaft, the bearing units and the supports therefor provide mechanical advantage to unbalancing weight distributions.

A device for use in supporting a circular member to determine whether it is balanced relative to its axis of rotation as defined by an axial shaft member extending from both sides of the circular member, spaced support members, each having an upwardly opening arcuate seat, and bearing units for each end of the axial member and of the type including inner and outer races and a series of rotatable members rotatably confined therebetween, the radius of each seat greater than that of each outer race, the outer race of each unit resting on and centered by the appropriate one of said seats and held against turning by the weight of the circular shaft members and the other race member of each unit free to turn as the axial member turns in response to any unbalancing weight distribution of the circular member, each shaft member end supported by a corresponding one of the inner races, and the diameter of each inner race greater than the diameter of the ends of the member it supports.
