What is the difference between EA Series and AG Series gear couplings?

EA Series Gear Couplings are designed for heavy-duty applications requiring high torque transmission and excellent shaft misalignment compensation. AG Series Gear Couplings are better suited for applications with different space, speed, or weight requirements while maintaining reliable power transmission.

What materials are used in EA Series Gear Couplings?

EA Series Gear Couplings are precision manufactured from high-strength EN9 steel and carbon steel. Each coupling is finished with a CED coating to provide superior corrosion resistance, wear protection, and long service life.

Can EA Series Gear Couplings accommodate shaft misalignment?

Yes. The crowned gear tooth design allows the coupling to compensate for angular, parallel, and axial shaft misalignment while maintaining smooth torque transmission and reducing stress on connected equipment.

How often should EA Series Gear Couplings be lubricated?

Under normal operating conditions, lubrication is recommended every six months or after approximately 3,000 hours of operation using a high-quality extreme-pressure (EP) grease. Regular lubrication helps maximize coupling life and performance.

Which industries commonly use EA Series Gear Couplings?

EA Series Gear Couplings are widely used in steel plants, cement plants, mining operations, power plants, sugar mills, and other heavy industrial applications that require reliable high-torque power transmission.

EA Series Gear Couplings

EA Series Gear Coupling Manufacturer India High Torque, Precision Engineered

AniGears Gear Couplings (AG and EA Series) are high-performance, torsionally rigid, flexible shaft couplings designed to transmit high torque between rotating shafts operating under demanding industrial conditions.

Torque is transmitted through accurately machined, hardened, and crowned gear teeth on the hubs, which engage with internal teeth on the sleeves. This design permits limited angular, parallel, and axial misalignment while maintaining compact dimensions and high torque capacity.

The AG Series (FGC Type) represents the heavy-duty range of Full Gear Couplings, available in Short Teeth (ST) and Long Teeth (LT) configurations to suit different torque and alignment requirements.

AniGears gear couplings are precision-engineered and supplied fully CED-coated for corrosion protection and long service life.

AniGears is a leading supplier and EA Series gear coupling manufacturer India. We design and produce heavy-duty mechanical transmission components that can handle high torques and prevent gear coupling for shaft misalignment. We produce our products in our state-of-the-art factories, from high-grade EN9 Steel Gear Coupling and have CED Coated Gear Coupling to make these units highly resistant to corrosion and long-term use.

Features & Advantages

Why Choose This Product

High Torque Density

The EA Series Gear Coupling was designed for a high power-to-weight ratio, making it the best high torque gear coupling in India for heavy machinery. It has a strong structure that transmits huge torque loads in a small space, which reduces the total overhung load on the shafts of the equipment it is coupling.

Crowned Gear Teeth

Specially designed as a gear coupling with crown teeth, the teeth on the hub's outside surface are profiled for optimised surface contact. This reduces stress concentration at the edges of the tooth in use, so that the tooth is less vulnerable to local wear and the motor has an effortless power transfer under load.

Double Engagement Flexibility

Flexible gear coupling supplier features a double engagement so that machines are mounted to accommodate both parallel and angular motions simultaneously while maintaining a consistent axial and parallel motion. The double engagement allows the unit to be an effective gear coupling for shaft misalignment that prevents premature bearing failure.

Standard & Long Turbo (ST/LT) Options

In order to accommodate shaft gaps and customer specifications, we offer these couplings in standard (ST) and long turbo (LT) versions. This flexibility allows the engineer to adjust the spacing without compromising the structural integrity or stiffness of the drivetrain.

Short Teeth (ST)

Allow greater angular flexibility and are recommended for drives where misalignment variations or shaft deflections are expected.

Long Teeth (LT)

Provide higher torque capacity and improved load distribution due to larger contact area but allow slightly lower misalignment.

Torsional Rigidity

The high torsional stiffness of the EN9 steel gear coupling ensures virtually zero backlash when driving at high speeds, in reverse or with heavy shock loads. With this high torsional stiffness, timing and synchronisation between the drive and drive shafts is ensured for all combinations.

Ease of Maintenance

Split sleeves are engineered with efficiency in mind, allowing for quick lubrication and alignment checks, as well as seal replacement. They provide a simple means of ensuring minimal machine downtime and ensuring critical industrial processes run without having to tear them down.

Premium Material Quality & Surface Treatment

Each unit is machined from EN9 steel gear coupling, carbon steel and finished in a special CED coated gear coupling finish to ensure wear and environmental resistance. Our raw materials and finished products are tested at NABL laboratories to ensure they meet the international engineering standards and make us a trusted Gear coupling manufacturer India. For lighter applications that require different damping characteristics, we offer options like AG Series Gear Couplings.

Applications

Industrial Applications of EA Series Gear Couplings

EA Series Gear Coupling for Steel Plants

Heavy-duty rolling mills, continuous casters, and hot strip mills all require heavy-duty transmission components capable of sustaining severe shock loads and unrelenting operation. The EA Series Gear Coupling for Steel Plants is built with the torsional strength and high-temperature resistance that keep heavy steel production lines running efficiently without catastrophic drivetrain failure.

EA Series Gear Coupling for Cement Plants

Cement plants face high levels of dust, vibration and torque requirements that are extremely high for kiln drives, ball mills, and heavy conveyors. Using a gear coupling like the EA Series gear coupling for cement plants will keep drives synchronised and protect against contaminating particulates, exceeding regular Tyre Couplings.

Gear Coupling for Mining Industry

Excavators, crushers and heavy-duty overland conveyors found in the mine operate at exceptionally high loads and in adverse environments. As a leading flexible gear coupling supplier, we have built heavy-duty couplings that absorb extremely high vibrations and protect the motors from sudden jams or shaft locks.

Gear Coupling for Power Plants

Constant power from turbines, fans in cooling towers, and large generator shafts needs to be precise and reliable. Our couplings provide the low-backlash execution and structural integrity needed to precisely synchronise large amounts of power at high speed, making them a strong alternative to the lighter Pin Bush Couplings used in main drive systems.

Gear Coupling for Sugar Mills

Sugar cane crushing mills run under high-torque and highly corrosive seasonal environments that put severe stress on drive shafts and mill rollers. Our high-capacity couplings provide reliable torque distribution and corrosion resistance required to navigate the crushing season smoothly, meaning less chance of breakdowns in high-demand moments.
