The Roller Fender is typically constructed from an energy-absorbing elastomer unit which is fixed onto a single rotating shaft. Self-lubricating and low-maintenance bearings are installed between the wheel and shaft for easy rotation even underwater. It may freely rotate while mounted in a steel enclosure. Roller Fenders’ primary function is to serve as a guiding mechanism for a secure and comfortable vessel movement in a narrow or sharp tuning channel.
Roller Fenders can be mounted in a variety of configurations, including stacked double or triple fenders in tide zones to cover higher elevations,
to maneuver the ship through a confined space, side by side installed at an angle that suits the vessel hull’s flare angles, etc.
