- 1A - ABSTRACT A conveyor roller comprises a roller tube fitted with end cap assemblies incorporating bearings for rotatably mounting the roller tube on a fixed shaft. Each end cap assembly comprises a rigid housing having a cylindrical collar adapted to be a push fit in an end of the roller tube, the outer end of the collar being spaced radially from the housing. The end cap assembly is secured in position by swaging the end of the tube so as to force the outer end of the collar radially inwards against the rigid housing. The collar may be a close fit on the housing, or the housing may be moulded in plastics material and one end of the collar embedded in the plastics during the moulding of the housing. The outer end of the collar has a flange which abuts the end of the roller tube. The outer surface of the housing is curved radially inwards in the direction of the free end of the collar to limit the deflection of the collar. The separate collar can have a thickness adapted to any particular diameter of roller tube, and may be connected to the housing by welding, adhesive or interengaging teeth or ribs to prevent relative rotation therebetween.
