How It Works

The F160 uses a large, reinforced elastomer tyre to transmit power between two heavy-duty flanges.

Torque Transmission: The massive rubber tyre connects the driving and driven hubs, transmitting torque through shear resistance. This flexible link eliminates metal-to-metal contact and requires no lubrication.
Shock Absorption: In applications like ball mills or crushers, the F160 tyre twists to cushion the drivetrain against sudden load spikes. This elasticity significantly reduces the stress on motor shafts and gearbox teeth.
Misalignment Tolerance: The F160 accommodates severe shaft errors—handling up to 4.2mm of parallel offset—allowing for thermal expansion and foundation settling without inducing heavy side loads on bearings.

Benefits of F160 Couplings

Extreme Power Capacity: Capable of transmitting over 500 kW at standard speeds, making it suitable for the heaviest industrial motors.
"Replace-in-Place" Maintenance: The split-tyre design allows maintenance teams to replace the flexible element without moving the heavy motor or driven machine, saving hours of downtime.
Vibration Damping: The natural rubber element isolates torsional vibrations, protecting sensitive equipment components from fatigue failure.
Lubrication Free: Zero grease or oil is required, ensuring a clean operation suitable for harsh or abrasive environments.
Safety: The non-conductive tyre electrically isolates the shafts and acts as a mechanical fuse, disconnecting the drive in the event of a catastrophic jam.

Typical Applications

The F160 is a critical component in heavy industry sectors:

Mining: Main drives for SAG mills, ball mills, and primary jaw crushers.
Bulk Handling: Overland conveyor main drives and ship loaders.
Metal Processing: Steel rolling mill drives and heavy shears.
Fluid Power: Large industrial pumps and dredge pumps.
Manufacturing: Heavy-duty mixers, extruders, and paper machinery.

Summary

The F160 Tyre Coupling is the ultimate heavy-duty power transmission solution. With a nominal torque rating of 3,770 Nm and the ability to absorb massive shock loads, it provides unmatched protection for high-value industrial assets. Whether driving a mill or a main conveyor, the F160 offers the durability and low-maintenance reliability required to keep heavy industry moving.
