Our Capabilities as a Internal Gear Manufacturer

Internal gears transmit power between parallel shafts, just like spur and helical gears. The big difference here is that the teeth point inward, toward the center of the gear. This type of gear is used mostly as a part of planetary gearboxes.

We also have internal and external shaper cutting capabilities up to 1800 mm diameter with up to a 150 mm gear face, and of 1600 mm diameter with 275 mm face width using our late model gear shaper, also holding up to an AGMA Class 8/9.

This is one of the largest Internal gear shapers in western India.

As An Internal Gear Manufacturer, We manufacture the following Types of Internal Gears.

Small & Large Diameter Internal Gears

We manufacture Girth gears in 2 segment construction or single piece depending on the application.

We supply these to the Cement, Steel, Mining, Engineering, Marine, Sugar Industries.
