Mechanical Snubber | Pneumatic Shock Absorbers

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. Airpot snubbers cover a wide range of low to moderate energy applications in which accurate control of impact, damping or shock absorption is required. The devices accomplish this by using the piston to force ambient air through an adjustable orifice at a controlled rate to dissipate kinetic energy and reduce impact, noise and wear. READ MORE

Airpot’s snubbers are specifically designed to provide unparalleled energy dissipation accuracy by eliminating friction from their working elements. The materials used have built-in lubricity, high strength-to-weight ratio, excellent stability under temperature/humidity extremes, close coefficients of thermal expansion, and non-deteriorating performance due to age or non-use. The basic parts are a graphitized carbon piston, precision ground to millionths of an inch TIR inside an annealed, borosilicate glass cylinder with a precision fire-polished bore. Airpot snubbers are available in 4 bore sizes ranging from 0.627” to 1.75” and strokes lengths of 1.1” to 2.3”

Snubber features (pneumatic shock absorption devices):

Not connected to the damped mass they are working with
Used in accurate end of stroke and shock absorbtion applications
Primary function is energy dissipation
One way only,(damping in compression)
Low force return spring for self resetting
