When controlled deceleration is required at the end of the stroke of your mechanism, the Airpot snubber configuration is particularly useful. It performs push damping only and the push rod is not connected to the work.
Application Examples
In office copiers (as shown below), an Airpot snubber damps the lens carriage at the end of its return stroke. Because of this controlled deceleration, impact noise and bounce are prevented, permitting faster machine operation. The Airpot return spring quickly resets the piston for the next cycle.
In semi-conductor wafer transport mechanisms, it dampens firm positioning against hard stops.
