About the Airtac SDA Ultra Thin Cylinder SDA100X30SB
The AirTAC SDA100X30SB is a double-acting single-rod compact cylinder engineered for heavy-duty automation within a minimal axial footprint. Utilizing a riveted body design, it conserves valuable machine depth where conventional round-body units cannot fit, while delivering a substantial 3927 N push at 0.5 MPa. This specific configuration includes a built-in piston magnet for position sensing and a male M26x1.5 threaded rod end for secure load coupling.
The 100 mm bore houses a robust 32 mm piston rod and utilizes PT3/8 ports to handle high airflow demands across its 30 mm stroke. End-of-travel deceleration is managed by a fixed NBR bumper rather than an adjustable cushion, meaning external shock absorbers should be specified for high-energy impacts. Circumferential grooves allow the mounting of AirTAC reed or electronic switches, leveraging the internal magnet to confirm piston position accurately.

Where the Airtac SDA Ultra Thin Cylinder SDA100X30SB Is Used
Stamping Press Ejection
Provides the heavy push force needed to eject thick metal blanks from stamping dies, utilizing the male M26x1.5 rod for rigid tooling attachment.
Palletizer Lift Station
Handles vertical lifting of heavy palletized loads where the short riveted body minimizes overhead clearance requirements.
Heavy Carton Sealing
Applies consistent downward pressure to close and seal large industrial cartons, with the internal magnet triggering reed or electronic switches to confirm cycle completion.
Is the Airtac SDA Ultra Thin Cylinder SDA100X30SB the Right Cylinder?
Selecting this 100 mm bore model provides a theoretical maximum push of 801 kgf at 1.0 MPa, with a safe working load around 2356 N (roughly 60% of the 0.5 MPa rating) and a vertical lift capacity of approximately 200.2 kg at a 2:1 safety margin. If your application requires slightly less force, the SDA80 offers 2513.3 N of push at 0.5 MPa; as the largest standard SDA size, stepping up would require a different cylinder series. When ordering, confirm the 100 mm bore, 30 mm stroke, PT3/8 porting, male M26x1.5 rod thread, and the integrated magnet. Remember that a standard compact cylinder drifts when air pressure is lost or the valve is centered, so an external rod lock or pilot-operated check valve is necessary for strict load 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 SDA100X30SB FAQ
This double-acting cylinder generates a push force of 3927 N and a pull force of 3524.9 N at 0.5 MPa. At 0.7 MPa, the push increases to 5497.8 N. The theoretical maximum push force is 801 kgf at 1.0 MPa.
No, the piston will drift if air is lost or the directional valve is centered. The fixed NBR bumper only decelerates the stroke near the end points and does not act as a locking brake. For vertical load holding, you must install an external rod lock or a pilot-operated check valve.
