About the Airtac SDA Ultra Thin Cylinder SDA16X40
The AirTAC SDA16X40 is a double-acting single-rod compact cylinder engineered for tight axial spaces. It provides a 100.5 N push and 86.4 N pull at 0.5 MPa, operating via an M5x0.8 port. Its riveted assembly integrates the barrel, rear cover, and piston to drastically reduce overall length compared to round-body units.
This 16mm bore unit travels 40mm on a 6mm piston rod. End stops rely on a fixed NBR bumper rather than an adjustable air cushion, meaning high-energy cycles may require external shock absorption. This specific SKU lacks a piston magnet, so position sensing is not supported without upgrading to the -S variant.

Where the Airtac SDA Ultra Thin Cylinder SDA16X40 Is Used
PCB Depaneling Ejector
Pushes separated circuit boards off a routing fixture with a 100.5 N extend force, fitting easily into dense electronics assembly machinery.
Lab Tube Sorting Gate
Actuates a diverter arm for blood sample racks, utilizing the 40mm stroke and short body depth to minimize the footprint of diagnostic equipment.
Small Carton Flap Folder
Tucks corrugated flaps on compact packaging lines, relying on the 86.4 N retract force to clear the path for the sealing head.
Is the Airtac SDA Ultra Thin Cylinder SDA16X40 the Right Cylinder?
For sizing context, stepping down to the SDA12 yields 56.5 N push at 0.5 MPa, while stepping up to the SDA20 provides 157.1 N. The 100.5 N output here translates to a safe working load around 60 N or a vertical lift of roughly 5.1 kg with a 2:1 margin. Confirm your ordering essentials: 16mm bore, 40mm stroke, M5x0.8 port, female M3x0.5 rod thread, and no magnet.
Note that a standard compact cylinder drifts when air pressure is lost or the valve centers. The fixed NBR bumper only decelerates the stroke end and does not function as a locking brake. If your fixture must maintain position during an air failure, integrate 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 SDA16X40 FAQ
This double-acting cylinder generates a 100.5 N push and 86.4 N pull at 0.5 MPa. At 0.7 MPa, push increases to 140.7 N and pull to 121 N. The theoretical maximum push is 21 kgf at 1.0 MPa, with an operating pressure range of 0.15-1.0 MPa.
No, this specific SKU does not include a piston magnet, so it cannot trigger AirTAC reed or electronic switches. You must select the SDA16X40S variant to enable position sensing. Additionally, end-of-travel deceleration is handled by a fixed NBR bumper, not an adjustable air cushion.
