The AirTAC SDA16X5S 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 SDA16X5S is a double-acting single-rod compact cylinder engineered for extremely tight axial spaces. It provides a push force of 100.5 N and a pull force of 86.4 N at 0.5 MPa, making it suitable for light-duty positioning. The integrated -S option denotes a built-in piston magnet, enabling precise end-of-stroke detection when paired with an AirTAC reed or electronic switch mounted in the body grooves.
This model features a 6 mm piston rod and a 5 mm stroke, utilizing an M5x0.8 air port. The riveted body design drastically reduces overall mounting depth compared to conventional round-body cylinders. End-stop energy is managed strictly by a fixed NBR bumper, which decelerates the piston near stroke end but does not function as an adjustable air cushion.

Provides a rapid 5 mm nudge to free printed circuit boards from test fixtures without overtravel, utilizing the 100.5 N extend force to safely clear delicate solder joints.
Acts as a compact diverter for low-viscosity fluids in analytical equipment, where the short 16 mm bore footprint preserves valuable interior chassis space and the magnet confirms valve seating.
Pushes small plastic or stamped metal components out of an injection mold cavity, relying on the fixed NBR bumper to absorb the sudden end-stop impact within a 5 mm travel window.
When sizing this 16 mm bore actuator, evaluate your force requirements against its 100.5 N push at 0.5 MPa. If your application demands less energy, stepping down to the SDA12 provides 56.5 N; conversely, upgrading to the SDA20 yields 157.1 N. To finalize your order, confirm the 5 mm stroke, M5x0.8 port, the female M3x0.5 rod-end thread, and the required -S magnet. Remember that a standard compact cylinder drifts if air pressure is lost, so install an external rod lock or pilot-operated check valve if your mechanism must hold a load safely during a pneumatic failure.
Quick checklist
This double-acting 16 mm bore cylinder generates 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. The theoretical maximum push is 21 kgf at 1.0 MPa. It operates between 0.15 and 1.0 MPa, with a speed range of 30-500 mm/s.
No. The SDA16X5S uses a fixed NBR bumper at each end to decelerate the piston, which is not a field-adjustable air cushion. Additionally, it will not hold a load if air pressure drops; the piston will drift. You must add an external rod lock or pilot-operated check valve for secure position holding.
