Full Gear Coupling FGC 16A/ FGC 116A - Gear Coupling

Key Specifications

• Approximate Maximum Torque Capacity: 800,000 Nm
• Total (Outer) Diameter (approx.): 1000 mm
• Maximum Suitable Shaft Diameter / Bore (max): ~ 490 mm
• Rated Speed (max): ~ 1,050 RPM

How It Works

The coupling comprises two hubs with crowned external gear-teeth mounted on the driving and driven shafts, and two outer sleeves with matching internal gear-teeth. As the driving shaft rotates, torque is transmitted through the meshed teeth to the driven shaft. The crowned-tooth profile and gear-sleeve design allow the coupling to tolerate angular, parallel and axial misalignments — ensuring smooth and reliable power transmission even under shaft misalignment or load variations. Proper lubrication (grease or oil) is recommended for smooth functioning and long service life.

Benefits

• Very high torque capacity: Suitable for extremely heavy-duty industrial applications requiring large torque transmission.
• Misalignment tolerance: Can accommodate angular, parallel and axial misalignments, reducing stress on shafts and bearings under load or thermal shifts.
• Shock and vibration absorption: Gear-coupling design helps absorb shock loads and damp vibrations under heavy or fluctuating loads.
• Durability and long service life: Forged/cast-steel hubs and sleeves with hardened, precision-machined gear teeth are designed for rugged, continuous service in harsh industrial environments.
• Compact for its capacity class: Despite its large capacity, coupling remains comparatively compact versus many alternatives for similar torque ratings.
• Maintenance-friendly (with correct lubrication): With proper lubrication and periodic maintenance, coupling can deliver long-term reliable operation under heavy loads.

Typical Applications

• Large-scale steel mills, rolling mills and heavy-duty metal-industry drives
• Cement plants, crushers, heavy conveyors, bulk material-handling systems
• Massive pumps, large compressors, blowers, fans, and heavy-duty machinery under continuous or high-load service
• Mining equipment, aggregate-handling plants, dredgers, and other rugged industrial drives with high torque demands and possible shaft misalignment or heavy shock loads
• Any very heavy-load industrial machinery requiring reliable power transmission under misalignment, shock, or fluctuating load conditions

Selection & Installation Considerations

• Ensure the driven machine’s torque and load requirements match the coupling’s capacity (≈ 800,000 Nm).
• Verify shaft diameter / bore dimensions (up to ~ 490 mm) for compatibility with FGC 16A.
• Confirm shaft speed does not exceed the coupling’s rated speed (~ 1,050 RPM).
• Allow sufficient space for coupling’s outer diameter (≈ 1000 mm) and ensure proper alignment tolerances during installation.
• Adopt correct lubrication (grease or oil as per operating temperature and load) and schedule regular maintenance to ensure smooth operation and longevity.
• For heavy-duty, high-load, variable-load or shock-prone environments — coupling’s robust design and flexibility makes it especially suitable.

Summary

Full Gear Coupling FGC 16A offers a top-tier, heavy-duty coupling solution capable of transmitting very high torque (≈ 800,000 Nm), accepting large shaft diameters (up to ~ 490 mm), and providing robust misalignment compensation and shock-absorption. Its rugged construction, high torque rating, and maintenance-friendly design make it ideal for large-scale industrial drives — such as steel mills, cement plants, mining equipment, heavy conveyors, crushers, large pumps/compressors, and other heavy-load machinery. With proper installation, alignment, and lubrication/maintenance, FGC 16A ensures reliable, long-lasting power transmission even under the most demanding industrial conditions.
