Gearboxes - GB Series

Electric Motors | Pumps | Motion Control | Gearboxes

The GB Series gearbox has been designed to reduce the speed of the motor whilst increasing the torque and is fully compatible with the PM Series DC motor. 

The gearboxes are sealed for life  and have a die-cast housing which although strong is also lightweight, increasing efficiency and making the units corrosion resistant.  As well as their efficiency, the GB Series are characteristically quiet in comparison to many competitor units.

Due to the customised nature of their development, the gearbox is offered in a 
choice of shaft diameters with either worm or helical 
gears, in either Delrin ®, steel or phosphor bronze material.
