A roller conveyor system is disclosed having a frame with a pair of spaced apart rails and at least one roller assembly having an elongated shaft. A first bearing assembly is secured to one rail while a second bearing assembly is secured to the other rail so that the bearing assemblies are aligned with each other and each bearing assembly includes an inner and outer race. The elongated roller shaft extends through the inner races of the bearing assemblies so that a flat formed on the shaft is radially aligned with the inner race of one of the bearing assemblies. A threaded fastener is then threadably secured to the bearing inner race and has one end adapted to abut against the shaft flat. With the fastener in abutment with the shaft flat, the other end of the fastener is substantially flush with an outer surface of the bearing race. An annular collar is then positioned over the outer surface of the bearing inner race and this collar has an inner diameter substantially the same as the outer diameter of the bearing inner race to thus hold the fastener in abutment with the shaft flat. At least one roller is then secured to an intermediate point of the shaft. |
