The AirTAC AirTAC SDA16X5BH 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 SDA16X5BH is a double-acting single-rod compact cylinder engineered for minimal axial footprint installations. 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 riveted body construction integrates the barrel and covers into a short assembly, saving valuable machine depth where a conventional round-body actuator cannot fit.
This specific configuration includes a male M5x0.8 threaded piston rod for direct load coupling, replacing the standard female M3x0.5 thread. It also utilizes a fluororubber (FKM) seal variant for enhanced thermal and oil resistance. The unit relies on a fixed NBR bumper at each end to decelerate the stroke, and because this SKU lacks the -S magnet option, it cannot support magnetic position sensing.

Applies the 100.5 N push force to nudge printed circuit boards into alignment on a pick-and-place conveyor, utilizing the 5mm stroke for micro-adjustments.
Actuates a pinch valve on automated chemical dispensing lines, where the FKM seals resist harsh fluid vapors and the compact body fits inside crowded fume hoods.
Delivers rapid 5mm clamping strokes to hold thin film lids against packaging trays, taking advantage of the short riveted body to minimize machine footprint.
When sizing this 16mm bore actuator, evaluate your force margins carefully. Stepping down to the SDA12 yields 56.5 N of push at 0.5 MPa, whereas stepping up to the SDA20 provides 157.1 N. The SDA16X5BH itself generates 100.5 N at 0.5 MPa, translating to a safe working load of roughly 60 N (about 60% of the rated push) and a vertical lift capacity of approximately 5.1 kg with a 2:1 safety margin. Ensure your setup avoids side loading on the 6mm rod.
To finalize your order, confirm the 16mm bore, 5mm stroke, M5x0.8 air port, male M5x0.8 rod thread (B), and FKM seal (H). Note that a standard double-acting cylinder drifts when air pressure is lost or the valve is centered; the fixed bumper only decelerates the piston near the stroke end and does not function as a locking brake. For suspended loads, integrate an external rod lock or a pilot-operated check valve.
Quick checklist
This double-acting 16mm bore cylinder outputs 100.5 N push and 86.4 N pull at 0.5 MPa. At 0.7 MPa, the push increases to 140.7 N. The theoretical maximum push force is 21 kgf at 1.0 MPa. It operates between 0.15 and 1.0 MPa, with a proof pressure of 1.5 MPa, and runs at speeds from 30 to 500 mm/s.
No, this specific SKU lacks the -S piston magnet, so it cannot trigger AirTAC reed or electronic switches. You would need to specify the -S option to enable sensing. Additionally, it uses fixed NBR bumpers to absorb end-stop impact rather than an adjustable air cushion, so external shock absorbers are recommended for high-energy cycles.
