We have been working on greaseless friction hinges that have a large range of torques. The unit shown in the picture is an early stage proof of concept for a 60 in-lb friction hinge with a life cycle of 40,000. The torques we produce can go from 20 – 60 in-lb. Many other torque ranges are available but I just wanted to use this one as an example. The materials use are corrosion resistant and can be used in a marine saltwater environment without degradation. It is also resistant to harsh chemicals.
