Airtac SDA Ultra Thin Cylinder SDA100X30H
The AirTAC Airtac SDA Ultra Thin Cylinder SDA100X30H is a genuine double-acting COMPACT (thin) air cylinder with a Ø100mm bore and 30mm stroke, PT3/8 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 SDA100X30H
The AirTAC SDA100X30H is a double-acting, single-rod compact cylinder engineered for heavy-duty operations within a minimal axial footprint. Utilizing a robust 100mm bore, it generates 3927 N of push force and 3524.9 N of pull force at 0.5 MPa. The riveted body design significantly reduces overall mounting depth compared to conventional round-body units, making it highly effective for machinery where space is strictly limited. This specific H-series configuration incorporates fluororubber (FKM) seals, providing enhanced resistance to elevated temperatures and oil exposure.
This model features a substantial 32mm piston rod and PT3/8 air ports to accommodate high airflow demands. End-of-stroke deceleration is managed by a fixed NBR bumper at each end, which absorbs impact energy but is not a field-adjustable air cushion. Because this SKU lacks the S option, it has no piston magnet and cannot support magnetic sensing; adding the -S variant would enable the use of reed or electronic switches in the body grooves.

Where the Airtac SDA Ultra Thin Cylinder SDA100X30H Is Used
Injection Mold Platen Ejection
Provides the high 3927 N push force needed to eject dense plastic parts from injection molding platens, utilizing the compact riveted body to fit within tight mold clamp footprints.
Heavy Gauge Metal Stamping
Delivers reliable holding power for positioning heavy-gauge sheet metal in stamping presses, where the 32mm rod withstands significant axial stress and the FKM seals resist thermal degradation.
Palletizer Lift Stations
Drives short 30mm vertical lift mechanisms in automated palletizing cells, moving loads up to 200.2 kg with a 2:1 safety factor while conserving vertical machine space.
Is the Airtac SDA Ultra Thin Cylinder SDA100X30H the Right Cylinder?
Selecting this 100mm bore unit is appropriate when substantial thrust is required, offering a safe working load of roughly 2356 N (about 60% of the 3927 N push force at 0.5 MPa) and a vertical lift capacity of approximately 200.2 kg with a 2:1 safety margin. If your application requires slightly less force, the SDA80 provides 2513.3 N of push at 0.5 MPa, serving as the next size down. Since 100mm is the largest bore in the SDA series, stepping up to a higher force class would require evaluating alternative non-SDA cylinder families.
When ordering, verify the 30mm stroke, PT3/8 porting, and the female M18x1.5 rod-end thread. Note that a plain double-acting cylinder does not hold its load if air pressure is lost or the valve is centered; the piston will drift, and the fixed bumper only decelerates near the stroke end rather than locking the rod. For applications requiring suspended load security, an external rod lock or pilot-operated check valve must be integrated.
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 SDA100X30H FAQ
This 100mm bore cylinder delivers a push force of 3927 N and a pull force of 3524.9 N at 0.5 MPa. At 0.7 MPa, the push force is 5497.8 N. The theoretical maximum push force is 801 kgf at 1.0 MPa, which is the maximum operating pressure. It operates at speeds between 30-500 mm/s.
No, this specific SKU does not include a piston magnet, so it cannot support magnetic sensing. To use AirTAC reed or electronic switches in the body grooves, you must order the SDA100X30HS variant, which includes the built-in magnet. Additionally, end-stop deceleration is handled by a fixed NBR bumper, not an adjustable air cushion.
