Reduction Gear Boxes
A reduction gear box is used to reduce an input speed to a slower output speed and more output torque. It is a wheel work consisting of a connected set of rotating gears by which power is transmitted or motion or torque is changed. We can manufacture and supply single stage, double stage or multistage gear boxes having Single and Multiple outputs as required.


From Low Speed to High Speed, technicalities of our Reduction Gear Boxes are:-

Casing / Housing / Structure Material Steel Fabricated
