Dashpots and Shock Absorbers

<< Back to Airpot page

Airpot’s pneumatic damping products are specifically designed to provide unparalleled damping and 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.

The Airpot Dashpot and Airpot Snubber cover a wide range of applications in which accurate control of motion, force and impact is required. The devices accomplish this by using the piston to force ambient air through an orifice at a controlled rate to dissipate kinetic energy. They prevent damage and violent or inaccurate response caused by shock and vibration in sensitive equipment and components, reduce impact noise and wear, provide simple, low cost, adjustable speed control without external power and allow non-electrical timing capability.

Product Lineup

Airpot Precision Dashpots

Airpot Precision Dashpots
When there is the need to reduce or eliminate harmful or excessive motion, Airpot dashpots offer highly accurate motion control, including vibration damping, spring damping, solenoid damping, and control of free fall velocity. Airpot’s precision glass cylinder and graphite piston technology produces instrument quality pneumatic devices uniquely designed and optimized for accurate, repeatable force control. The result is a family of damping devices that operate with superior accuracy and little or no friction. Airpot “Accurate Force ” precision dashpots use ambient air to precisely and accurately control force, velocity and impact and are ideal for designing or improving a product line or building specialized equipment to do research, high level testing or precision assembly. Airpot Air Dashpots are available in 6 bore diameters ranging from .22 inches to 1.75 inches with either push, pull, or two-way damping and strokes from 0.5 inches to 3 inches.

Snubbers (Pneumatic Shock Absorbers)

Airpot Snubbers (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.

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
