About the Airtac SDA Ultra Thin Cylinder SDA100X30BH
The AirTAC SDA100X30BH is a double-acting single-rod compact cylinder engineered for heavy-duty automation within a minimal axial footprint. Utilizing a riveted assembly, the body drastically reduces mounting depth compared to conventional round-body units, delivering a robust 3927 N push force at 0.5 MPa. This specific SKU includes a male M26x1.5 piston rod thread (M18x1.5 female default) and an FKM fluororubber seal option for enhanced thermal and oil resistance.
It features a 100mm bore with a 32mm piston rod and PT3/8 air ports. End-stroke deceleration is handled by a fixed NBR bumper rather than an adjustable cushion, meaning external shock absorbers should be added for high-energy cycles. Note that this configuration omits the piston magnet, so magnetic position sensing is not supported without the -S option.

Where the Airtac SDA Ultra Thin Cylinder SDA100X30BH Is Used
Stamping Press Ejection
Ejects heavy formed metal panels from stamping dies using 3927 N of extend force, where the short riveted body fits within tight press tooling clearances.
Palletizer Lift Station
Raises lowerator forks handling 200 kg product loads, relying on the 32mm rod and M26x1.5 male thread to securely couple with heavy guided tooling plates.
Industrial Crate Sealing
Applies high downward clamping pressure on large shipping crates during strapping, utilizing the FKM seals to withstand elevated ambient temperatures in shrink-wrap tunnels.
Is the Airtac SDA Ultra Thin Cylinder SDA100X30BH the Right Cylinder?
When sizing this actuator, evaluate stepping down to the SDA80, which provides 2513.3 N push at 0.5 MPa, or stepping up to larger profile cylinders if your application exceeds this unit's 100mm bore capacity. The SDA100X30BH yields a safe working load of roughly 2356 N (about 60% of the 3927 N figure at 0.5 MPa), translating to a vertical lift capacity of approximately 200.2 kg with a 2:1 safety margin.
Remember that a standard double-acting cylinder drifts when air pressure is lost or the valve is centered, as the fixed bumper only decelerates the stroke end rather than locking the load. To maintain position vertically, an external rod lock or pilot-operated check valve is mandatory. Confirm your ordering essentials: 100mm bore, 30mm stroke, PT3/8 ports, FKM seals, male M26x1.5 rod, and no sensor 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 SDA100X30BH FAQ
At 0.5 MPa, the push force is 3927 N and the pull force is 3524.9 N. At 0.7 MPa, the push force is 5497.8 N and the pull force is 4934.8 N. The theoretical maximum push force is 801 kgf at the maximum operating pressure of 1.0 MPa.
No, this specific SKU lacks the -S piston magnet, so it cannot trigger AirTAC reed or electronic switches. Additionally, it uses a fixed NBR bumper for end-stop deceleration rather than an adjustable air cushion, so external shock absorbers may be needed for high-speed operations.
