The AirTAC AirTAC SDA16X25H 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 SDA16X25H is a double-acting, single-rod compact cylinder engineered for tight machinery footprints. Its riveted body assembly reduces overall axial length compared to round-body alternatives, yielding a 100.5 N push force at 0.5 MPa. This specific H-series configuration utilizes a fluororubber (FKM) seal to sustain demanding thermal and oil-exposure conditions.
The unit features a 6 mm piston rod and an M5x0.8 air port. End-stop deceleration relies on a fixed NBR bumper rather than a field-adjustable air cushion, meaning operators should slow the approach or utilize external shock absorbers for high-energy loads. Because this SKU lacks the -S magnet suffix, it cannot directly host AirTAC reed or electronic switches.

Actuates a low-profile routing blade in electronics assembly, where the short riveted body fits within dense conveyor machinery and the FKM seal withstands localized heat.
Provides the 100.5 N push force required to close small thermoforming molds, saving axial mounting space on high-speed packaging lines.
Drives a precision dosing valve for chemical reagents, leveraging the fluororubber seals for oil resistance while keeping the instrument footprint minimal.
When sizing this 16 mm bore actuator, evaluate your force margins carefully. Stepping down to the SDA12 provides 56.5 N of push at 0.5 MPa, while stepping up to the SDA20 yields 157.1 N. The SDA16X25H provides a safe working load of roughly 60 N (about 60% of its 100.5 N capacity) and can vertically lift approximately 5.1 kg with a 2:1 safety factor.
Remember that a standard compact cylinder drifts when air pressure is lost or the valve centers; the fixed bumper only decelerates the stroke end and does not function as a locking brake. To maintain position, integrate an external rod lock or a pilot-operated check valve. To order, confirm the 16 mm bore, 25 mm stroke, M5x0.8 port, female M3x0.5 rod thread, and the FKM seal requirement.
Quick checklist
This double-acting cylinder generates a 100.5 N push and 86.4 N pull at 0.5 MPa. At 0.7 MPa, the push increases to 140.7 N. The theoretical maximum push is 21 kgf at 1.0 MPa. It operates between 0.15-1.0 MPa, with a proof pressure of 1.5 MPa, and runs at speeds of 30-500 mm/s.
No, this specific SKU does not include a piston magnet, so it cannot host AirTAC reed or electronic switches. You would need the -S option for sensing capabilities. Additionally, it uses a fixed NBR bumper for end-stop deceleration, which is not an adjustable air cushion.
