Review on Bansbach Easylift FDT 47A 203 Rotary Dampers by Mark Adams

Not enough information here or on the company website to really know how much force is required to turn the bushing. It actually needs quite a bit of torque, making them unusable for my application. It requires so much torque that you need a perfectly machined square shaft to fit the square hole or you will deform and destroy the plastic. A metal core would be much stronger than a plastic core.
