<p>The roller assemblies of a roller conveyor each comprise a collar 12 mounted on a roller support shaft 4 or 6 and having a radial end flange 13, and an annular roller 16 freely rotatable on the collar between the radial end flange and an annular cap 14 mounted on the opposite end of the collar and serving as an opposing radial end flange. The collar 12 is fastened to the associated shaft, so as to be driven thereby, by a pin 17 which also serves to fasten the cap 14 to the collar. The collar, cap and roller are formed as sintered components from material including a major portion of iron. <IMAGE></p> |
