About the Airtac SDA Ultra Thin Cylinder SDA100X30SBH
The AirTAC SDA100X30SBH is a double-acting, single-rod compact cylinder engineered for heavy-duty automation within a minimal axial footprint. Utilizing a riveted assembly, the body is significantly shorter than traditional round-body units, saving valuable machine mounting depth. At 100 mm bore, it generates 3927 N of push force and 3524.9 N of pull force at 0.5 MPa, with a theoretical maximum output of 801 kgf at 1.0 MPa.
This configuration includes the -S magnet for position sensing via AirTAC reed or electronic switches, a -B male M26x1.5 piston rod thread for secure load coupling, and -H fluororubber (FKM) seals for enhanced thermal and oil resistance. The unit relies on a fixed NBR bumper at each end to decelerate the stroke, operating effectively between -20 and +70 C at speeds of 30-500 mm/s.

Where the Airtac SDA Ultra Thin Cylinder SDA100X30SBH Is Used
Stamping Press Ejection
Provides the heavy push force required to eject thick metal blanks from progressive stamping dies, utilizing the 32 mm rod to withstand high impact loads.
Palletizer Lift Station
Lifts heavy product layers onto shipping pallets, where the short riveted body minimizes vertical space requirements and the FKM seals resist oily environments.
Injection Mold Separation
Drives the separation of large injection molding tooling halves, using the male M26x1.5 thread for rigid coupling to the moving platen.
Is the Airtac SDA Ultra Thin Cylinder SDA100X30SBH the Right Cylinder?
When sizing this actuator, evaluate stepping down to the SDA80, which yields 2513.3 N of push force at 0.5 MPa, or stepping up if a larger bore were available. For this 100 mm bore, the computed safe working load is approximately 2356 N (about 60% of the 3927 N figure), translating to a vertical lift capacity of roughly 200.2 kg with a 2:1 safety margin. Confirm your ordering essentials: 100 mm bore, 30 mm stroke, PT3/8 port, male M26x1.5 rod thread, FKM seals, and a built-in magnet.
Remember that a plain compact cylinder does not hold its load if air pressure is lost or the valve is centered; the piston will drift. The fixed NBR bumper only decelerates the stroke near the end and does not act as a lock or brake. To maintain a vertical load without live pressure, you must 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 SDA100X30SBH FAQ
This 100 mm bore model uses a PT3/8 air port. The force output is 3927 N push and 3524.9 N pull at 0.5 MPa, and 5497.8 N push and 4934.8 N pull at 0.7 MPa. The theoretical maximum push force is 801 kgf at 1.0 MPa.
No, the SDA series uses a fixed NBR bumper at each end to decelerate the stroke, not an adjustable air cushion. For high-speed or high-energy cycles, you should add an external shock absorber or slow down the approach speed.
