How It Works

The F180 utilizes a massive, reinforced natural rubber or FRAS tyre to connect two steel flanges.

Torque Transmission: The driving flange engages the tyre, which transmits rotation to the driven flange through shear force. This non-rigid connection eliminates metal-to-metal wear and electrically isolates the connected machinery.
Shock Cushioning: In high-impact applications like primary crushers, the F180 tyre twists to absorb kinetic energy from load spikes, acting as a buffer that prevents catastrophic shaft fatigue and gearbox damage.
Misalignment Tolerance: The F180 is capable of accommodating severe shaft errors—handling up to 4.8mm of parallel offset—allowing for thermal expansion and foundation shifting without stressing support bearings.

Benefits of F180 Couplings

Extreme Power Capacity: Capable of transmitting nearly 1 Megawatt of power at standard speeds, making it suitable for the largest industrial drives.
Maintenance Efficiency: The "split-tyre" design allows for replacement without moving the massive motor or driven machine, saving tens of man-hours during shutdowns.
Lubrication Free: Requires no grease or oil, ensuring low-maintenance operation even in dirty, dusty, or inaccessible locations.
Vibration Damping: The elastomeric element inherently dampens torsional vibrations, reducing noise and protecting sensitive gears and bearings.
Safety: In the event of a seizure, the tyre acts as a mechanical fuse, tearing to disconnect the drive and protect the expensive capital equipment.

Typical Applications

The F180 is employed in the heaviest industrial sectors:

Mining & Aggregates: Main drives for large SAG mills, ball mills, and gyratory crushers.
Bulk Handling: Overland conveyor systems and ship loaders.
Fluid Power: Massive slurry pumps and industrial fans.
Metal Processing: Steel rolling mill main drives.
Marine: Heavy-duty propulsion and dredging equipment.

Summary

The F180 Tyre Coupling is the ultimate solution for heavy-duty power transmission. With a nominal torque rating of 6,270 Nm and the capacity to handle up to 4.8mm of parallel misalignment, it provides robust protection for high-value machinery. Its combination of shock absorption, vibration damping, and "fit and forget" reliability makes it the standard for critical heavy industrial infrastructure.
