The AirTAC AirTAC SDA16X50BH Compact Cylinder | 16mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø16mm bore and 50mm 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 SDA16X50BH 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. Equipped with a fluororubber (FKM) seal, this unit handles higher temperature and oil resistance demands. The riveted body assembly keeps the overall length exceptionally short, conserving machine footprint where a conventional round-body unit would be too deep.
This specific configuration includes a male M5x0.8 threaded piston rod for straightforward load coupling, replacing the standard female M3x0.5 end. It operates at speeds between 30 and 500 mm/s using an M5x0.8 port. End-stop deceleration is managed strictly by fixed NBR bumpers rather than an adjustable air cushion. Because this SKU lacks the -S magnet option, it cannot support magnetic reed or electronic switches.

Uses the 100.5 N extend force to push separated circuit boards out of a routing fixture, where the short 50 mm stroke and FKM seals resist ambient flux fumes.
Folds cardboard carton flaps at high cycle rates, relying on the male M5x0.8 rod end for secure mounting and the compact body to fit within narrow side frames.
Actuates a precision metering valve for adhesive application, taking advantage of the 30-500 mm/s speed range and the 5.1 kg vertical lift margin to depress the nozzle.
When sizing this 16 mm bore actuator, compare its 100.5 N push at 0.5 MPa against adjacent options. Stepping down to the SDA12 yields 56.5 N, while stepping up to the SDA20 provides 157.1 N. For practical payloads, expect a safe working load around 60 N (roughly 60% of the 0.5 MPa figure) or a vertical lift capacity near 5.1 kg with a 2:1 safety margin. To finalize your order, confirm the 16 mm bore, 50 mm stroke, M5x0.8 port, male M5 rod thread, FKM seals, and the absence of a piston magnet.
Keep in mind that a standard compact cylinder cannot hold a load if air pressure drops or the valve is centered. The piston will drift, and the fixed NBR bumper only decelerates the stroke near its end without acting as a mechanical lock. If your application requires position holding without live pressure, you must integrate an external rod lock or a pilot-operated check valve.
Quick checklist
This double-acting cylinder provides a push force of 100.5 N and a pull force of 86.4 N at 0.5 MPa. At 0.7 MPa, the push increases to 140.7 N and the pull to 121 N. The theoretical maximum push is 21 kgf at 1.0 MPa, with a proof pressure of 1.5 MPa.
No. This specific SKU does not include the -S piston magnet, so it cannot trigger AirTAC reed or electronic switches. You would need to select the -S variant to utilize the built-in magnetic switch grooves around the body.
