The F200 Tyre Coupling is a high-capacity flexible coupling designed for extremely heavy industrial power transmission. As one of the largest sizes in the standard tyre coupling range, the F200 is engineered to transmit massive torque loads while maintaining the essential elasticity required to absorb severe shock loads and dampen vibrations in critical machinery.

How It Works

The F200 utilizes a massive, reinforced rubber tyre element to transmit torque between two heavy steel flanges.

Torque Transmission: The driving flange rotates the flexible tyre, which transfers the immense rotational force to the driven flange through shear stress. This non-rigid connection eliminates metal-to-metal wear and electrically isolates the shafts.
Shock Load Damping: In high-impact applications like SAG mills or jaw crushers, the F200 tyre twists to absorb kinetic energy from sudden load spikes, acting as a buffer that prevents catastrophic shaft breakage.
Misalignment Compensation: The F200 allows for substantial shaft movement—accommodating up to 5.3mm of parallel offset—which is critical for large machinery that experiences thermal expansion or foundation settling.

Benefits of F200 Couplings

Massive Power Capacity: Capable of transmitting nearly 1,400 kW at standard motor speeds (1440 RPM), making it suitable for the largest industrial drives.
"Replace-in-Place": The split-tyre element allows for replacement without moving the heavy motor or driven machine, a critical feature for reducing downtime on massive equipment.
Lubrication Free: Requires no grease or oil, ensuring low-maintenance operation and eliminating contamination risks in dusty mining environments.
Vibration Isolation: The elastomeric element effectively isolates torsional vibration, protecting sensitive downstream gears and bearings from fatigue.
Safety: In the event of a catastrophic jam, the tyre will tear sacrificially, disconnecting the drive and saving the expensive capital equipment from destruction.

Typical Applications

The F200 is widely used in heavy industry where reliability is paramount:

Mining & Aggregates: Main drives for large ball mills, rod mills, and primary crushers.
Bulk Handling: Overland conveyor main drives and heavy-duty bucket wheels.
Fluid Power: Massive slurry pumps and industrial fans.
Metal Processing: Steel rolling mill drives and heavy coilers.
Marine: Main propulsion drives and large dredge pumps.

Summary

The F200 Tyre Coupling is the ultimate solution for heavy-duty power transmission. With a nominal torque rating of 9,325 Nm and the ability to absorb significant shock loads, it provides unmatched protection for high-value industrial assets. Whether driving a massive mill or a critical conveyor, the F200 offers the strength, flexibility, and ease of maintenance required to keep heavy industry running.
