Abstract
A freerunning roller for use in a roller conveyor system comprises a cylindrical tube having saw cut ends providing a rough edge on each end which is relied upon to effect frictional interengagement with a relatively soft plastic cup dimensioned for force fitting into the tube and also dimensioned internally to receive a ball bearing in force fitted relation. The bearing assembly is completed by a bushing which is force fitted into the bearing and also has a hexagonal bore for receiving a hexagonal shaft by which the roller is mounted in a conveyor frame.
Claims4
The method of fabricating a free-running roller for use in a roller conveyor system which comprises the steps of:
- (a) saw cutting both ends of a cylindrical tube to a predetermined length having a rough edge on each end thereof,
- (b) press fitting into each end of said tube an annular cup composed of plastic material of a consistency which will readily adapt itself to said rough edge on said tube, and
- (c) press fitting an anti-friction bearing into each said cup.
