Drive power for the SR48P is supplied by a heavy-duty, industrial quality gear reduction motor and roller chain directly to the gear train. The roll drive is controlled by a toggle action, shrouded foot pedal for instant forward and reverse action. The drive motor is equipped with an electromagnetic brake to prevent roll creep and over-forming.

Electrical and operator safety features include a full-length, front and back wire cable safety mechanism which instantly stops the rolls when tripped; two magnetic motor starters; fully enclosed electrical box with pilot light; insulated reinforced conduit for all wiring; and fully enclosed drive train. The rolls and gears are mounted in hardened bronze bushings for long life and precision operation.
