The AirTAC AirTAC SDA16X5B Compact Cylinder | 16mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø16mm bore and 5mm 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 SDA16X5B 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, making it suitable for light-duty positioning. The riveted body design drastically reduces overall length compared to round-body alternatives, saving valuable mounting depth.
This specific SKU includes a male M5x0.8 threaded piston rod for straightforward load coupling, replacing the standard female M3x0.5 thread. It features a hard-anodized 16 mm bore and relies on a fixed NBR bumper at each end to decelerate the stroke. Because this unit lacks the -S magnet option, it cannot host AirTAC reed or electronic switches.

Provides a rapid 5 mm extension to push bare circuit boards out of testing fixtures using 100.5 N of force without stressing the delicate fiberglass substrate.
Actuates a small cutting blade or nipper arm on a vertical form-fill-seal machine, where the short 16 mm bore body avoids interfering with the wrapping paper path.
Taps a micro-dispense valve for chemical reagents, utilizing the male M5x0.8 rod end to mount a custom dosing tip securely.
When sizing this 16 mm bore actuator, 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 5 mm stroke variant, the safe working load is approximately 60 N (about 60% of the 100.5 N figure), allowing a vertical lift of roughly 5.1 kg with a 2:1 safety margin. Ensure you specify the M5x0.8 port, the male M5x0.8 rod thread, and the absence of a piston magnet when ordering.
Keep in mind that a standard compact cylinder will not hold a load if air pressure drops or the valve is centered; the piston will drift. The fixed NBR bumper only decelerates the motion near the stroke end and does not act as a locking brake. If your application requires position holding without live pressure, you must integrate an external rod lock or a pilot-operated check valve.
Quick checklist
At 0.5 MPa, this double-acting cylinder provides 100.5 N of push force and 86.4 N of pull force. At 0.7 MPa, the push increases to 140.7 N. The theoretical maximum push force is 21 kgf at the 1.0 MPa operating pressure limit.
No, this specific SKU does not include a piston magnet, so it cannot trigger AirTAC reed or electronic switches. You would need to order the -S variant (SDA16X5BS) to enable sensor feedback along the body grooves.
