The AirTAC AirTAC SDA16X70S Compact Cylinder | 16mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø16mm bore and 70mm 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 SDA16X70S is a double-acting, single-rod compact cylinder engineered for tight machinery footprints. Its riveted assembly shrinks the overall axial length compared to round-body units, yielding a theoretical push of 100.5 N at 0.5 MPa. This specific 70 mm stroke exceeds the 60 mm standard maximum for this 16 mm bore, classifying it as a non-standard, made-to-order item.
Because the -S option is present, a built-in piston magnet enables position detection via an AirTAC reed or electronic switch seated in the body grooves. End-stopping relies strictly on a fixed NBR bumper rather than an adjustable air cushion, meaning operators should slow the approach or mount an external shock absorber for high-energy cycles. The 6 mm rod and M5x0.8 port ensure straightforward pneumatic and mechanical integration.

Uses the 100.5 N extend force to push singulated circuit boards out of a routing fixture, where the short riveted body prevents collision with adjacent tooling.
Drives a 70 mm stroke to depress a pipette head, relying on the -S magnet to trigger an AirTAC reed or electronic switch for precise fluid volume dosing.
Tucks lightweight cardboard flaps on a packaging line, where the fixed NBR bumper absorbs the end stop without requiring bulky adjustable cushion hardware.
When sizing this unit, consider stepping down to the SDA12, which provides 56.5 N of push at 0.5 MPa, or moving up to the SDA20, which offers 157.1 N at the same pressure. For this 16 mm bore, a safe working load is roughly 60 N (about 60% of the 100.5 N figure), allowing a vertical lift of approximately 5.1 kg with a 2:1 safety margin. To confirm your ordering essentials: specify the 16 mm bore, 70 mm non-standard stroke, M5x0.8 port, female M3x0.5 rod thread, and the required -S magnet.
Keep in mind that a standard SDA body does not hold its load if air pressure drops or the valve is centered, as the piston will drift and the fixed bumper only decelerates near the stroke end. If your application must maintain position without live pressure, incorporate an external rod lock or a pilot-operated check valve.
Quick checklist
This 16 mm bore double-acting cylinder generates a push of 100.5 N and a pull of 86.4 N at 0.5 MPa. At 0.7 MPa, the push increases to 140.7 N. The theoretical maximum push force is 21 kgf at 1.0 MPa.
No, a 70 mm stroke exceeds the 60 mm standard maximum for this bore, making it a non-standard, made-to-order configuration. Additionally, the cylinder uses a fixed NBR bumper to decelerate the piston at stroke end, which is not an adjustable air cushion.
