Gears & Gear Boxes

We specialize in manufacturing premium quality gears and gear boxes that provide smooth and trouble free operation. Accurately machined, completely enclosed, our gear boxes have sufficient lubrication and are completely dust proof. Double roller bearings are used and oil seals are provided outside bearings of pinion gear boxes to protect oil leakages. Our range includes Gear Couplings, Flexo Type Couplings, C.I. Couplings, Reduction Gear Box, Speed Increaser, SISO/SIDO/SITO Gear Boxes, Gears, Pinion Gear Box.

Gear Couplings

Gear Couplings
Industrial Gear Couplings are used for transmitting torque and power between two shafts. It is normally used for the coupling of Motor to fly-wheel, fly-wheel to gear box etc. Individually designed and manufactured to specific requirements.

It is a Triple crowned double engagement type with Hexagonal and Allen Bolt, forced greased type having reamed flange hole. We provide half and full gear couplings of 101 and above sizes as per customer requirement.

Flexo Type Couplings
The Flexo Type Couplings is a compact & lightweight coupling that uses nylon sleeves as a device for shaft coupling & torque transferring. Lubrication is not required with the nylon sleeve and they are highly effective for high RPM. the Flexo Type Couplings are effectively used in applications such as motor / generator sets, motor / pump sets, and many other industrial settings.

C.I. Couplings

C.I. Couplings
C.I. Couplings are inserted at the journal of the rolls, to couple the mill stands. These are basically for the power transmission from one stand to another.

Manufactured out of forged steel, they are highly applicable at mill stands with repeaters or high loads.

They are designed and manufactured as per the load of the application.

Reduction Gearboxes
Reduction gearboxes are 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 gearboxes having Single and Multiple outputs as required

From Low Speed to High Speed, technicalities of our Reduction Gearboxes are:

Normal Input Load Range From 50 HP upto 5000 HP. Drives
Gear Type Spur. Single & Double Helical Gears, Bevel Gears, Worm Gear Box upto 2500mm Dia

Apart from Rolling Mill gear boxes, we also manufacture the gear boxes according to the customer requirement, if relevant data is provided.
