Asia Instrument A2-25FZ Pneumatic Shock Absorber

The Asia Instrument Co. A2-25FZ Pneumatic Shock Absorber is a compact, flange-mount damper designed to control impact and stop-motion dynamics in automated equipment. It offers a 25 mm stroke and is rated for a maximum equivalent load of 2,000 kg, making it suitable for cushioning moving masses without excessive rebound. For the integrated-flange version, the overall length is 147 mm, and the body weighs roughly 0.02 lb (about 9 g). The A2-25FZ designation is listed as discontinued by the manufacturer, though replacement variants and compatible substitutes appear in distributor catalogs (for example, FA-4225B3-C-SF). This shock absorber is used where compact, end-of-travel damping is required in production automation and machinery, providing predictable deceleration and return action while maintaining a small footprint.
