About the Airtac SDA Ultra Thin Cylinder SDA16X5
The AirTAC SDA16X5 is a double-acting single-rod compact cylinder engineered for minimal axial mounting depth. By utilizing a short riveted body that merges the barrel, rear cover, piston and rod, it achieves an exceptionally small footprint where round-body units cannot fit. Delivering 100.5 N of push force at 0.5 MPa, it operates via an M5x0.8 port and features a hard-anodized bore with a two-way piston seal.
This specific configuration has a 5 mm stroke and lacks a piston magnet, meaning it cannot support magnetic sensing. End-of-travel deceleration is handled strictly by a fixed NBR bumper rather than an adjustable air cushion. For applications requiring position feedback, the -S variant adds a magnet compatible with reed or electronic switches mounted in the body grooves.

Where the Airtac SDA Ultra Thin Cylinder SDA16X5 Is Used
PCB Ejector Pins
Provides a compact 5 mm ejection stroke to push bare printed circuit boards out of test fixtures without consuming valuable Z-axis height.
Microchip Pick-and-Place
Acts as a short-throw diverter in semiconductor handling rails, using its 100.5 N thrust to nudge components into the next processing lane.
Lab Dispenser Valving
Toggles a small pneumatic valve for chemical dispensing, where the 16 mm bore delivers precise metering force within a tight analytical instrument chassis.
Is the Airtac SDA Ultra Thin Cylinder SDA16X5 the Right Cylinder?
When sizing this 16 mm bore actuator, consider stepping down to the SDA12 which provides 56.5 N of push at 0.5 MPa for lighter duties, or moving up to the SDA20 which yields 157.1 N if your mechanism requires greater thrust. The computed safe working load for this model is roughly 60 N (about 60% of the 100.5 N figure at 0.5 MPa), translating to a vertical lift capacity of approximately 5.1 kg with a 2:1 safety margin. To order, confirm the 16 mm bore, 5 mm stroke, M5x0.8 port, female M3x0.5 rod thread, and the absence of the magnet option. Note that a plain cylinder does not hold its load on air loss or valve centering; the piston drifts and the fixed bumper only decelerates near the stroke end, so an external rod lock or pilot-operated check valve is required for position holding.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Short-body depth vs. a round-body cylinder
- ✓ Port/thread type (PT)
- ✓ Magnet (S) for sensors?
- ✓ Female (blank) or male (B) rod thread
- ✓ Side load — avoid on a compact rod
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the short piston rod.
- check Very long strokes are unsuitable for the compact body.
- check Front/rear covers are riveted — do not dismantle.
- check Installation by qualified personnel per AirTAC docs.
Airtac SDA Ultra Thin Cylinder SDA16X5 FAQ
The SDA16X5 generates 100.5 N push and 86.4 N pull at 0.5 MPa, and 140.7 N push at 0.7 MPa. The theoretical maximum push force is 21 kgf at 1.0 MPa. Operating pressure ranges from 0.15 to 1.0 MPa, with a proof pressure of 1.5 MPa.
No adjustable air cushion is present; end stops rely solely on a fixed NBR bumper. For high speeds you should add an external shock absorber. This SKU lacks a piston magnet, so it cannot take a magnetic switch; you must specify the -S option for reed or electronic switch compatibility.
