The Heli Worm Gear Boxes/Reduction Gear Units are worm type units with modular construction. The units comprise of hardened ground worms with centrifugally cast bronze gears.

The Worm Gear Boxes/Reduction Gear Units when combined with an additional Helical Gear Unit can give particularly low output speeds. The helical gears are hardened and ground to close tolerances.

	Heli-worm units are suitable for low output speeds and high torque requirements
	One or two output shafts.
	Foot or flange mounted.
	Hollow input for standard IEC motors.
	Hollow output for direct shaft mounting.
