We are currently using ball screw to drive some of our elevator products. We found the use of ball screw a bit noisy and would like to try yout ball screw nut in order to achieve some testing. We have a 1'' diameter screw with 4 thread/inch. The nut should be able to sustain 2500 lbs, which is 5 time the actual load of the elevator, to keep a safety factor.Is there any way to get a sample in order to achieve some mechanical and functionnal testing? Please advise
