Plastic universal joint couplings use a mechanical pivotal action controlled by radial bearings. The Huco Flex P coupling range is injection moulded in acetal with controlled preload to eliminate backlash. This type of coupling has a large offset capacity along with good torsional damping and water resistance. They are also lubrication free. The double jointed versions include a cardan which enables them to also handle radial and angular misalignment.
The Huco-Pol range is suitable for use in light duty applications. Their low mass and corrosion resistance make them ideal for applications where conventional steel joints would be under-utilised. They are often used in food, textile, paper handling and packaging environments.
