The AirTAC SDA16X30S Compact Cylinder | 16mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø16mm bore and 30mm 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 SDA16X30S is a double-acting single-rod compact cylinder engineered for tight spaces. It delivers 100.5 N of push force and 86.4 N of pull force at 0.5 MPa. The short riveted body drastically reduces axial mounting depth compared to round-body alternatives, making it highly effective for shrinking machine footprints in dense layouts.
This unit includes a built-in piston magnet (-S) for direct mounting of AirTAC reed or electronic switches along the body grooves. It features a 6 mm piston rod, an M5x0.8 port, and relies on a fixed NBR bumper at each end to decelerate the stroke. This bumper is not an adjustable air cushion, so external shock absorbers should be added for high-energy cycles.

Provides precise 30 mm lateral adjustment on a conveyor routing bare printed circuit boards, utilizing the 100.5 N push force to gently square panels before optical inspection.
Actuates a short mechanical arm to tuck minor flaps on small pharmaceutical cartons, where the compact riveted body fits neatly between parallel packaging belts.
Moves a pipette head 30 mm downward into reagent trays, with the integrated magnet triggering a solid-state switch to confirm liquid dispensing depth.
When sizing this actuator, evaluate your force needs carefully. Stepping down to the SDA12 provides 56.5 N of push at 0.5 MPa, while stepping up to the SDA20 yields 157.1 N. Confirm your ordering essentials: 16 mm bore, 30 mm stroke, M5x0.8 port, female rod thread, and the integrated magnet. Note that a plain compact cylinder drifts when air pressure is lost or the valve is centered—the fixed bumper only decelerates near stroke end and does not function as a lock or brake. To hold a load securely without live pressure, an external rod lock or pilot-operated check valve is required.
Quick checklist
At 0.5 MPa, the push force is 100.5 N and the pull force is 86.4 N. At 0.7 MPa, the push is 140.7 N and pull is 121 N. The theoretical maximum push is 21 kgf at 1.0 MPa, which is the maximum operating pressure.
No. It uses a fixed NBR bumper to decelerate at stroke end, which is not a field-adjustable air cushion. Additionally, it does not hold its load if air is lost; the piston drifts. An external rod lock or pilot-operated check valve is required for position holding.
