Live-Conveyor Rollers | McMaster-Carr
Also known as line-shaft conveyors, these are driven by a drive shaft and round belts. The drive shaft continues to run even when the accumulation of packages may cause some rollers to stop turning. Conveyors can be hardwired for material flow in either direction. Only straight conveyor sections contain a motor and can power up to 60 ft. of conveyor extensions on either side.
