Airtac SDA Ultra Thin Cylinder SDA16X20
The AirTAC SDA Ultra Thin Cylinder SDA16X20 is a genuine double-acting COMPACT (thin) air cylinder with a Ø16mm bore and 20mm 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.

About the Airtac SDA Ultra Thin Cylinder SDA16X20
The AirTAC SDA16X20 is a double-acting single-rod compact cylinder engineered for tight machinery footprints, delivering 100.5 N of push force and 86.4 N of pull force at 0.5 MPa. Its riveted assembly merges the barrel, rear cover, piston, and rod to drastically reduce overall length compared to round-body units. The 16 mm bore features a hard-anodized inner wall and a two-way piston seal for reliable low-friction operation.
This specific configuration uses a 6 mm piston rod with an M5x0.8 air port and a default female M3x0.5 rod-end thread. End-of-travel deceleration is handled by a fixed NBR bumper rather than an adjustable cushion, meaning external shock absorbers should be added for high-energy cycles. Because this SKU lacks the -S magnet option, it cannot host magnetic position sensors.

Where the Airtac SDA Ultra Thin Cylinder SDA16X20 Is Used
PCB Depaneling Ejector
Provides a short 20 mm kick to separate routed circuit boards on an SMT line, utilizing the compact 16 mm footprint to fit between dense tooling.
Blister Pack Flap Tucker
Folds cardboard inserts with 100.5 N of push force at 0.5 MPa, ensuring cartons are sealed properly before entering the case packer.
Lab Dispenser Valve Actuation
Drives a micro-metering valve for chemical reagents where a 5.1 kg vertical lift margin is sufficient and axial mounting depth is highly restricted.
Is the Airtac SDA Ultra Thin Cylinder SDA16X20 the Right Cylinder?
When sizing this unit, evaluate your neighbours: stepping down to the SDA12 yields 56.5 N push at 0.5 MPa, while moving up to the SDA20 provides 157.1 N. Confirm your ordering essentials: 16 mm bore, 20 mm stroke, M5x0.8 port, female rod thread, and no sensor magnet.
Note that a standard double-acting cylinder drifts when air pressure is lost or the valve is centred. The fixed NBR bumper only softens the impact near the stroke endpoints and does not function as a braking lock. If your mechanism must hold a load vertically without live pressure, install an external rod lock or a pilot-operated check valve.
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 SDA16X20 FAQ
This double-acting cylinder 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 is 21 kgf at 1.0 MPa. It operates between 0.15-1.0 MPa, with a proof pressure of 1.5 MPa, and runs at speeds of 30-500 mm/s.
No, this specific SKU does not include the -S piston magnet, so it cannot trigger AirTAC reed or electronic sensors. You would need to specify the SDA16X20S variant to enable position sensing. Additionally, end-stop deceleration relies on a fixed NBR bumper, not an adjustable air cushion.
