GNA Gears

Bull Pinion Shafts are manufactured with an outer dia. up to 450 mm. These are either carburized or induction hardened as per customer specification. Quality grade is maintained up to DIN 9. We can cut upto 450 dia and 8 modules. In the cutting section we have CNC Hobbing and Shaving and have capabilty to supply in din 8. We can make these Bull Pinion Shafts using both the carburising and induction route.

Gear Boxes for agricultural applications such as Rotavators, Combines & Tractors. Range includes ratio - 1:1 / 1. 8:1 / 1.77:1

Hollow Shafts are manufactured using CNC Deep Hole Drilling Machine with the capacity to accommodate up to 1 meter length and drill dia ranging from 4mm to 27mm. Splined shafts are manufactured in the range of 100mm to 1600mm.

Speed Gears are made up to 250 mm outer dia. module up to 5 and high range of accuracy up to DIN 7. Independent line to make Speed Gears. Cell concept and on line inspection and packaging to avoid transit dents. We are equipped to make Clutch Gears; Gears with Bush Fitting and cut upto 8 module . Can produce quality in din 7/8.

Range varies from 50 dia to 500 dia and 11 module. Crown Wheel & Tail Pinion at GNA Gears are cut using the state-of-the-art KLINGELNBERG Dry Cutting Technology. We can also cut using both the Face Milling and Face Hobbing Route. This technology advantageously facilitates root step elimination and a pitch line run out of less then 20 microns, eventually delivering a better noise level. To support this set up we have CGCF, a Press Quenching set up in the Heat Treatment and AICHELIN SQF Furnace with one tonne capacity.

We are equipped with the capability of making Ring Gears through both the Broaching as well as Shaping route. For shaping GNA Gears will soon be imbibing the Power Skiving Technology while the rings will be cut using Klingelnberg Dry Cutting. Other than that we are equipped with Shaping and Broaching machines upto 110 ton capacity and we can cut rings upto 500 dia. To support in Heat Treatment we have Plug Quenching for Carburised Ring and CNC Induction Hardening Machines for inductioned rings.
