Pneumatic shock absorber for industrial use

The Festo DYSR-25-40-Y5 is a pneumatic shock absorber built for controlled deceleration in automated systems. It handles kinetic energy in linear or rotary motion applications where precise end-position damping is required. The unit is supplied new in a single pack under part number 1138648.

Suited for machine builders and maintenance teams

Engineers designing pneumatic cylinders, rotary actuators or pick-and-place units will find this absorber matches the specified stroke and energy ratings. Buyers who need adjustable damping, hydraulic operation or a different mounting pattern should look at alternative product lines.

Stroke and bore define the fit

The 25 mm stroke and 40 mm bore are the critical dimensions that determine whether this absorber matches your cylinder or actuator. Verify these figures against your mechanical design before ordering.

Questions about this item

How do I install the DYSR-25-40-Y5 pneumatic shock absorber and what step is often missed?

Mount the unit using its 25 mm bore and 40 mm stroke dimensions, then connect the air supply; the step often missed is verifying the piston rod alignment before pressurising the system.

What maintenance or replacement will the DYSR-25-40-Y5 need over time?

The manufacturer covers parts for three years and labour for one year; plan to inspect seals and damping fluid at regular intervals and replace the absorber once its energy capacity drops below spec.

What limit appears first on the DYSR-25-40-Y5 during continuous cycling?

The 25 mm bore and 40 mm stroke define the maximum energy per cycle; sustained high-frequency operation hits this thermal limit first, causing temperature rise and reduced damping consistency.
