Danfoss Aluminum Gear Motors

Aluminum Gear Motors

Aluminum gear motor Gr1

  • A high efficiency and a light weight aluminum construction
  • Pressure balanced bearing blocks for maximum performance across operating range
  • Teflon® coated bushings extend life under extreme temperature, pressure and speed conditions
  • One piece gears minimize deflection under pressure
  • An excellent starting torque
