The AirTAC AirTAC SDA16X35B Compact Cylinder | 16mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø16mm bore and 35mm 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 SDA16X35B is a double-acting, single-rod compact cylinder engineered for tight axial spaces. It delivers a push force of 100.5 N and a pull force of 86.4 N at 0.5 MPa, making it well-suited for light-duty positioning. The riveted unibody design merges the barrel, rear cover, piston, and rod to drastically reduce overall length compared to conventional round-body units.
This specific SKU features a male M5x0.8 threaded piston rod end for direct mechanical coupling to your load. The bore is hard-anodized for wear resistance, and deceleration at the stroke extremes is handled by a fixed NBR bumper rather than an adjustable air cushion. Note that this configuration lacks a piston magnet, so it cannot host position-sensing switches.

Drives delicate test probes onto printed circuit boards with a safe 60 N working load, utilizing the short 35 mm stroke to minimize fixture height.
Actuates a lightweight sorting flap on a packaging conveyor, where the male M5x0.8 rod end secures the linkage and the compact body fits within the guardrail.
Moves a fluid dispensing nozzle vertically in a laboratory automation rig, relying on the 5.1 kg vertical lift capacity to raise and lower the valve assembly.
When sizing this 16 mm bore actuator, evaluate your force margins carefully. Stepping down to the SDA12 reduces the push output to 56.5 N at 0.5 MPa, whereas stepping up to the SDA20 increases it to 157.1 N. Based on the 100.5 N output, a safe working load is approximately 60 N (around 60% capacity), which translates to a vertical lift capability of roughly 5.1 kg with a 2:1 safety margin.
Remember that a standard double-acting cylinder drifts when air pressure is lost or the valve is centered, as the fixed bumper only decelerates the stroke end without locking the piston. If your mechanism must hold a load safely without live pressure, integrate an external rod lock or a pilot-operated check valve. To order, confirm the 16 mm bore, 35 mm stroke, M5x0.8 port, male M5x0.8 rod thread, and the absence of a magnet.
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. The theoretical maximum push is 21 kgf at 1.0 MPa. It operates on filtered air between 0.15 and 1.0 MPa, with a speed range of 30-500 mm/s.
No, this specific SKU lacks the internal piston magnet, so it cannot support AirTAC reed or electronic switches. Additionally, it uses a fixed NBR bumper at each end to absorb end-stop impact; it does not have a field-adjustable air cushion, so external shock absorbers are recommended for high-energy loads.
