The AirTAC AirTAC SDA16X25S Compact Cylinder | 16mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø16mm bore and 25mm stroke, M5×0.8 air ports and a riveted short body that saves mounting depth. Sensor slots around the body accept magnetic switches for position sensing.
The AirTAC SDA16X25S is a double-acting single-rod compact cylinder engineered for tight machinery layouts. It produces a 100.5 N extend force at 0.5 MPa, yielding a safe working load around 60 N and a vertical lift capacity near 5.1 kg with a 2:1 margin. The riveted unibody construction merges the barrel, covers, and piston to drastically reduce axial mounting depth compared to conventional round-body units.
This 16 mm bore variant incorporates a built-in piston magnet for position detection via AirTAC reed or electronic switches seated in the body grooves. It uses a 6 mm rod with a standard M5x0.8 air port. Deceleration at stroke limits relies on fixed NBR bumpers rather than adjustable cushions, meaning high-energy cycles may require external shock absorbers.

Drives small vertical grippers in electronics assembly lines where the 100.5 N extend force securely lifts delicate circuit boards.
Applies precise clamping pressure on thin film packaging machinery within a shallow frame, utilizing the 25 mm stroke for rapid cycling.
Indexes fluid valves on automated analyzer units, relying on the built-in magnet to trigger electronic switches for exact dosing volumes.
When sizing this actuator, evaluate stepping down to the SDA12 which provides 56.5 N of push at 0.5 MPa, or moving up to the SDA20 which delivers 157.1 N. To finalize your order, confirm the 16 mm bore, 25 mm stroke, M5x0.8 port, the integrated S magnet, and your preferred female M3x0.5 rod-end thread. Note that a standard cylinder drifts if air pressure drops or the valve centers; the fixed bumper only slows the piston near the end of travel and does not function as a locking brake. To suspend a load safely without live pressure, install an external rod lock or pilot-operated check valve.
Quick checklist
At 0.5 MPa this cylinder provides 100.5 N of push and 86.4 N of pull. At 0.7 MPa the push is 140.7 N and pull is 121 N. The theoretical maximum push force is 21 kgf at 1.0 MPa.
It uses fixed NBR bumpers to decelerate the piston at the ends; these are not adjustable air cushions. The S designation means it has a built-in magnet for AirTAC reed or electronic switches, allowing you to mount sensors directly in the body grooves for position detection.
