With products engineered for everything from the marine industry to heavy-duty industrial machinery and grinding mills, drum-style Eaton Airflex constricting clutches and brakes are available with a variety of torque capacities and other features to meet the requirements of the most demanding jobs.
Rugged tire-like constricting tube
Force applied uniformly at optimum radius
Wide torque capacity range
Four models excel at starting and stopping heavy-duty equipment in harsh conditions
CB – the perfect fit for high-speed cyclic operations, coupling and general power transmission
CM – specifically engineered for the marine industry on diesel-driven, reverse-reduction gears
VC – handle large inertia loads and sustained slippage on heavy-duty applications
HEVC – increases energy capacity and allows for longer slip times in severe clutching and braking applications
How constricting elements work
Eaton Airflex constricting drum clutch and brake elements use a rugged, tire-like neoprene and cord tube that expands radially inward when pressurized. The expansion forces a friction surface against a cylindrical drum to create torque.
