A roller assembly (10) is provided having a roller (12) to which two shafts (14, 16) are fixedly secured by means of modular hub assemblies (18). The hub assemblies (18) each have a roller flange (20) which is fixedly secured to the roller (12), usually by welding. A shaft flange (26) is provided for fixedly securing directly to a respective one of the shafts (14, 16), preferably with a pressed fit. The shafts (14, 16) have tapered end sections (64) which fit in direct contact with tapered holes (32) formed into the roller flanges (20). The roller flanges (20 are further recessed to each provide a recessed surface (36) which fits flush against an inward facing surface (48) of the shaft flange (26) to provide a friction engagement there-between. The shaft flange (26) is preferably threadingly secured to the roller flange (20).
