How It Works

The F100 utilizes a heavy-duty, reinforced rubber tyre element to transmit torque between two metal flanges.

Torque Transmission: The driving flange engages the tyre, which transfers the rotational force to the driven flange through shear stress. This flexible connection eliminates the metal-to-metal wear found in rigid couplings.
Shock Load Absorption: The substantial rubber element acts as a cushion. When the driven machine experiences a sudden load spike (e.g., a rock entering a crusher), the tyre twists to absorb the energy, preventing damage to the motor shaft.
Misalignment Compensation: The F100 allows for significant shaft movement—up to 2.6mm parallel offset—accommodating thermal expansion and foundation settling without stressing support bearings.

Benefits of F100 Couplings

High Power Capacity: Capable of transmitting nearly 100 kW at standard motor speeds, suitable for heavy industrial drives.
Simplified Maintenance: The split-tyre design allows for "replace-in-place" maintenance, meaning the rubber element can be changed without moving the heavy motor or gearbox.
Vibration Isolation: The elastomeric tyre effectively dampens torsional vibration, ensuring smoother operation and reducing noise levels.
Lubrication Free: Requires no grease or oil, eliminating contamination risks and reducing maintenance costs.
Operational Safety: The tyre acts as a fuse; in a catastrophic overload, it will tear to disconnect the drive, saving the expensive capital equipment.

Typical Applications

The F100 is widely used in heavy industry where reliability is paramount:

Mining & Quarrying: Jaw crushers, cone crushers, and ball mills.
Bulk Handling: Heavy-duty belt conveyors and bucket elevators.
Fluid Handling: Large slurry pumps and piston compressors.
Processing: Industrial mixers, agitators, and extruders.
Metal Industry: Rolling mill auxiliary drives and shears.

Summary

The F100 Tyre Coupling is a premier choice for heavy-duty power transmission. With a nominal torque rating of 624 Nm and the capacity to handle up to 2.6mm of parallel misalignment, it provides robust protection for high-value machinery. Its combination of shock absorption, vibration damping, and low-maintenance operation makes it an industry standard for demanding applications.
