Airtac SDA Ultra Thin Cylinder SDA16X50
The AirTAC SDA Ultra Thin Cylinder SDA16X50 is a genuine double-acting COMPACT (thin) air cylinder with a Ø16mm bore and 50mm 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 SDA16X50
The AirTAC SDA16X50 is a double-acting, single-rod compact cylinder engineered for tight axial spaces. It generates 100.5 N of push force and 86.4 N of pull force at 0.5 MPa, making it suitable for light-duty positioning. The hard-anodized bore and two-way piston seal ensure reliable service within its 30-500 mm/s speed range.
This 16 mm bore model features a 6 mm piston rod and an M5x0.8 air port. Its riveted body design drastically reduces overall length compared to round-body alternatives. The stroke end is decelerated by a fixed NBR bumper rather than an adjustable air cushion, meaning external shock absorbers should be added for high-energy cycles. This specific SKU lacks a piston magnet and therefore cannot support magnetic sensing.

Where the Airtac SDA Ultra Thin Cylinder SDA16X50 Is Used
PCB Depaneling Ejector
Provides the 100.5 N push stroke needed to eject cut circuit boards from a routing fixture without damaging delicate traces.
Lab Dispenser Actuation
Drives a 50 mm stroke to depress a micropipette or syringe head, offering precise fluid metering within compact benchtop enclosures.
Small Carton Flap Folder
Folds lightweight cardboard tuck flaps on a packaging line, fitting neatly into narrow side-frame gaps where profile cylinders cannot mount.
Is the Airtac SDA Ultra Thin Cylinder SDA16X50 the Right Cylinder?
When sizing this actuator, stepping down to the SDA12 provides 56.5 N of push at 0.5 MPa, while stepping up to the SDA20 yields 157.1 N. If your application requires position holding upon air loss, note that this unit will drift; an external rod lock or pilot-operated check valve is required. To order, confirm the 16 mm bore, 50 mm stroke, M5x0.8 port, female rod thread, and no magnet.
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 SDA16X50 FAQ
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 to 1.0 MPa, with a proof pressure of 1.5 MPa.
No, this specific SKU is built without a piston magnet. To use AirTAC reed or electronic switches in the body grooves, you must select the SDA16X50S variant. Additionally, this model uses a fixed NBR bumper for end-stop deceleration, not an adjustable air cushion.
