Abstract
A bearing includes an inner race member having an end surface. An outer race member is disposed about the inner race member. The outer race member has an internal shoulder for engaging the end surface of the inner race member. The inner and outer race members are configured to define a raceway between them and to define a snap ring seat between them. There are cylindrical rollers in the raceway and a snap ring in the snap ring seat. The bearing may be provided as a follower head on a cam follower or may be eccentrically mounted on a drive shaft to serve as a cam. A cargo dolly may include such a cam near a wheel, to help the wheel overcome an obstacle. A bearing can be assembled by inserting the inner race member into the outer race member, disposing cylindrical rollers in the raceway and disposing a snap ring in the snap ring seat.
