Long Teeth Full Gear Coupling
At Sahara Engineers, we design and manufacture high-precision Long Teeth Full Gear Couplings tailored for demanding industrial applications. As a leading gear coupling manufacturer and exporter based in Ahmedabad, we provide robust, high torque couplings with extended life, ideal for heavy machinery and power transmission systems across diverse sectors.
Long teeth gear couplings differ from standard gear couplings by extending the tooth length of the mating gear elements, enabling better load distribution, higher capacity, and improved flexibility.
Features & Technical Specifications
- Extended gear tooth length for enhanced contact area and better torque transmission
- High load capacity, with ability to handle heavy radial and axial loads
- Tolerance for misalignment (angular, parallel, axial) while maintaining efficient power transfer
- Backlash control, precise gear profiles to limit play
- Interchangeable components, facilitating easier maintenance
- Made to custom dimensions — bore sizes, keyways, hub sizes as per your drawings or requirements
Key Features
- Forged alloy steels (e.g. EN-8, EN-19, or equivalent)
- Hardened teeth surfaces (case hardening, carburizing, nitriding)
- Shot blasting and protective coatings (e.g. anti-rust painting, galvanizing)
Materials & Treatments
Technical Data (Indicative Ranges)
| Parameter | Typical Range* |
| Bore diameter | As per customer specification, up to large sizes |
| Torque capacity | Depends on size — suitable for high torque industrial applications |
| Gear module | Engineered per design to match load and application |
| Maximum rpm | As per design and balancing |
| Misalignment capacity | Designed to permit small angular / parallel misalignment |
* Actual values depend on coupling size, gear profile, and application.
We manufacture these couplings to precise tolerances and can accommodate non-standard designs like extended bores, keyways, flanges, and special hub configurations.

Applications & Industries Served
Our Long Teeth Full Gear Couplings are well-suited for heavy-duty industrial environments. Typical applications include:
Because of their ability to handle high torques and tolerate alignment deviations, they are often used where reliability and long service life are essential.
Design Advantages & Performance Benefits
1. Improved Load Distribution
The longer teeth allow the load to be distributed over a larger contact surface, reducing stress concentration and extending gear life.
2. Higher Torque Capacity
Extended teeth permit transmitting higher torques for the same gear module, making the coupling more compact for a given load.
3. Enhanced Misalignment Tolerance
While still being rigid in design, the long teeth help accommodate small misalignments more gracefully than very short teeth couplings.
4. Reduced Wear & Noise
Better gear mesh reduces local wear, vibration, and noise under heavy operations.
5. Ease of Replacement & Maintenance
Interchangeable teeth sleeves or hubs can be replaced without full system disassembly. Spare parts can be standardized.
- State-of-the-art CNC machining, gear hobbing/milling, and finishing
