About the Airtac SDA Ultra Thin Cylinder SDA100X20BH
The AirTAC SDA100X20BH is a double-acting single-rod compact cylinder engineered for heavy-duty tasks within confined axial footprints. Utilizing a riveted body assembly, it saves mounting depth compared to conventional round-body units while delivering a substantial 3927 N push at 0.5 MPa. This specific configuration includes an FKM fluororubber seal for heightened oil and thermal resilience, operating reliably across a 30-500 mm/s speed range.
Equipped with a robust 32 mm piston rod, this model features a male M26x1.5 thread end for direct mechanical coupling. The unit relies on a fixed NBR bumper at each stroke terminus to absorb impact energy rather than an adjustable air cushion. Because this SKU lacks the -S magnet option, it cannot host reed or electronic switches; position sensing requires the -S variant instead.

Where the Airtac SDA Ultra Thin Cylinder SDA100X20BH Is Used
Injection Mold Platen Ejection
Drives heavy ejector pins on a 200-ton injection molding platen, utilizing the 20 mm stroke and 3927 N force to break plastic parts free from the mold cavity.
Hydraulic Press Stamping
Positions thick steel blanks inside a hydraulic stamping press where short axial depth is critical, leveraging the FKM seals to withstand elevated ambient heat.
Palletizer Stopper Gate
Acts as a heavy-duty stopper gate on an automated palletizer conveyor, using the male M26x1.5 rod to securely halt incoming 200 kg pallet loads.
Is the Airtac SDA Ultra Thin Cylinder SDA100X20BH the Right Cylinder?
When sizing this actuator, evaluate stepping down to the SDA80, which yields 2513.3 N push at 0.5 MPa, or stepping up if a larger bore existed beyond 100 mm. The 100 mm bore achieves a theoretical maximum push of 801 kgf at 1.0 MPa. For practical design targets, the safe working load calculates to roughly 2356 N (about 60% of the 3927 N figure at 0.5 MPa), allowing a vertical lift of approximately 200.2 kg with a 2:1 safety margin.
Confirm your ordering essentials: 100 mm bore, 20 mm stroke, PT3/8 port, male M26x1.5 rod thread, and FKM seals. Note that a plain actuator does not hold its load if air pressure drops or the valve centers—the piston drifts, and the fixed bumper only decelerates near the stroke end. To suspend a load securely without live pressure, install 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 SDA100X20BH FAQ
This 100 mm bore model uses PT3/8 ports and generates a push of 3927 N and pull of 3524.9 N at 0.5 MPa. At 0.7 MPa, push is 5497.8 N and pull is 4934.8 N. The theoretical maximum push is 801 kgf at 1.0 MPa.
No. This SKU lacks the -S magnet, so it cannot accept reed or electronic switches. Additionally, it uses a fixed NBR bumper to decelerate the stroke end rather than an adjustable air cushion; for high-energy cycles, add an external shock absorber.
