The AirTAC AirTAC SDA16X30B 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 SDA16X30B is a double-acting single-rod compact cylinder engineered for tight axial spaces. It delivers 100.5 N of push force and 86.4 N of pull force at 0.5 MPa. A short riveted body joins the barrel, rear cover, and piston, saving valuable mounting depth where a round-body unit will not fit. The bore is hard-anodized and uses a two-way piston seal for reliable operation.
This specific SKU includes a male M5x0.8 piston rod thread for direct load coupling, replacing the default female M3x0.5. It features an M5x0.8 air port and operates at speeds between 30-500 mm/s. Because this model lacks the -S suffix, it has no piston magnet and cannot accept magnetic switches. End-stopping is handled by a fixed NBR bumper, which decelerates the piston but is not an adjustable air cushion.

Actuates a routing bit guard or small clamping jaw in electronics manufacturing, utilizing the 30mm stroke and 100.5 N force within a compact machinery footprint.
Drives a micro-pipette or small valve actuator for fluid metering, where the 5.1 kg vertical lift margin and male M5x0.8 thread provide secure, precise load coupling.
Folds minor flaps on small packaging lines, benefiting from the short riveted body to fit within narrow conveyor side frames without external shock absorbers.
When sizing this 16mm bore, step down to the SDA12 for 56.5 N of push at 0.5 MPa, or step up to the SDA20 for 157.1 N at 0.5 MPa. For this 100.5 N configuration, a safe working load is roughly 60 N (about 60% of the 0.5 MPa figure), yielding a vertical lift capacity near 5.1 kg with a 2:1 safety margin. To order, confirm the 16mm bore, 30mm stroke, M5x0.8 port, male M5x0.8 rod thread (B), and no magnet. Note that a plain cylinder drifts when air is lost or the valve is centered; the fixed bumper only decelerates near stroke end and does not act as a lock. Use an external rod lock or pilot-operated check valve if the application requires position holding.
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, push is 140.7 N and pull is 121 N. The theoretical maximum push is 21 kgf at 1.0 MPa. Operating pressure ranges from 0.15-1.0 MPa, with a proof pressure of 1.5 MPa and a speed range of 30-500 mm/s.
No, this specific SKU does not have a piston magnet, so it cannot accept reed or electronic switches. You would need the -S variant for sensing. Additionally, it uses a fixed NBR bumper at each end to decelerate the stroke, which is not an adjustable air cushion.
