The AirTAC AirTAC SDA16X70 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 SDA16X70 is a double-acting, single-rod compact cylinder engineered for tight axial spaces. It generates 100.5 N of push force and 86.4 N of pull force at 0.5 MPa. Because the 70 mm stroke exceeds the 60 mm maximum standard stroke for this 16 mm bore, this specific unit is manufactured as a non-standard, made-to-order configuration.
The short riveted body drastically reduces mounting depth compared to round-body alternatives, making it ideal for densely packed machinery. End-of-travel deceleration relies on a fixed NBR bumper rather than an adjustable air cushion, meaning operators should slow the approach or add external shock absorbers for high-energy loads. This SKU omits the piston magnet, so magnetic position sensing is not supported without upgrading to the -S option.

Provides a compact 70 mm kick to separate routed circuit boards on an SMT line, fitting neatly within tight electronics assembly fixtures.
Tucks end flaps on pharmaceutical cartoning equipment, delivering 100.5 N of extend force to fold lightweight cardboard accurately.
Shifts microtitre plates into a diagnostic scanner using a 6 mm piston rod, saving valuable axial footprint on crowded laboratory benches.
When sizing this actuator, evaluate your neighbours: stepping down to the SDA12 yields 56.5 N of push at 0.5 MPa, while stepping up to the SDA20 provides 157.1 N. For the SDA16X70, a safe working load is approximately 60 N (about 60% of the 100.5 N figure), translating to a vertical lift capacity near 5.1 kg with a 2:1 safety margin. To order, confirm the 16 mm bore, 70 mm non-standard stroke, M5x0.8 port, female rod thread (M3x0.5), and the absence of a magnet.
Keep in mind that a standard double-acting cylinder drifts when air pressure is lost or the valve is centred. The fixed NBR bumper only decelerates the piston near the stroke end and does not function as a locking brake. If your application must hold a load without live pressure, install an external rod lock or a pilot-operated check valve.
Quick checklist
This 16 mm bore actuator outputs 100.5 N push and 86.4 N pull at 0.5 MPa, or 140.7 N push and 121 N pull at 0.7 MPa. The theoretical maximum push force is 21 kgf at 1.0 MPa, with an operating pressure range of 0.15-1.0 MPa.
No, this specific SKU lacks the internal piston magnet, so it cannot trigger AirTAC reed or electronic switches. You would need to specify the SDA16X70S variant to enable magnetic position sensing.
