dampening

(OP)
Anyone heard of a hydraulic damper or any damper that is capable of decelerating small loads (30-75lbs) in about(.015-.030") of travel.  I have a high speed application where a roller on a spring loaded pivot cylces up and down.  Up and down of varying strokes. .010" - .030".  I need some thing to take away the impact noise when the mechanism bottoms out.  I can't use a bumper because the hard stop must be precise, and the components must resist wear.  i can only think of slowing the impact to reduce the noise with some sort of damper.  Any help on this would be greatly appreciated.

RE: dampening

Is this a good question for the "piping & Fluid mechanics" forum ?

  

RE: dampening

Seems to me this is a perfect appliation for a Crankshaft or an Eccentric Drive that has adjustable stroke. However, I,m not sure if the adjustable stroke is possible with these mechanisms.
