What are the ranges of motion of a hydraulic snubber?

Hydraulic snubbers are designed with a pre-defined amount of stroke. Those stroke ratings are available in 6 inch increments from 6″ to 24″. The amount of movement, which could be accommodated by any stroke designation, would depend upon the initial setting. For example, setting a 6″ stroke snubber at the midpoint would mean that during operation, the snubber could extend 3″ maximum or retract 3″ maximum.
