We rotate our PVC rollers with AM hubs and sprockets. We make sure that we buy flat end caps for the PVC so the hub will mount easily. We usually run a shaft through the entire roller to help keep everything in line and eliminate side load. We use plates with bearings to support the whole system and then run 25 chain from the motor/transmission sprocket to the shaft sprocket of the roller. Sometimes we use hex shaft and other times we use keyed shaft. It all depends on how much force the roller needs to handle. This has always worked for us and has never failed in the 4+ seasons we have needed a roller.
