About the Airtac SDA Ultra Thin Cylinder SDA100X35SB
The AirTAC SDA100X35SB is a double-acting, single-rod compact cylinder engineered for heavy-duty automation within a minimal axial footprint. Utilizing a riveted body assembly, it conserves machine space where conventional round-body or profile units cannot fit, delivering a substantial 3927 N push force 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 operates on PT3/8 ports and relies on a fixed NBR bumper at each stroke end to decelerate the payload. Because this bumper is not an adjustable air cushion, high-energy cycles may require an external shock absorber. The hard-anodized inner wall and two-way piston seal ensure durability across the 30-500 mm/s speed range at operating pressures up to 1.0 MPa.

Where the Airtac SDA Ultra Thin Cylinder SDA100X35SB Is Used
Stamping Press Ejection
Provides the heavy 3927 N push force required to knock thick steel blanks from a stamping press die, utilizing the male M26x1.5 rod for rugged die-coupling.
Palletizer Lift Station
Handles vertical lifting of heavy palletized goods, where the compact riveted body minimizes overhead machinery dimensions and the built-in magnet tracks position.
Injection Mold Separation
Delivers the brute force needed to break large plastic injection molds apart, relying on the fixed NBR bumper to absorb the shock at the end of the 35 mm stroke.
Is the Airtac SDA Ultra Thin Cylinder SDA100X35SB the Right Cylinder?
Selecting this 100 mm bore provides a massive 3927 N push at 0.5 MPa, yielding a safe working load of roughly 2356 N (about 60% of capacity) and a vertical lift capability of approximately 200.2 kg with a 2:1 safety margin. If your application requires less force, stepping down to the SDA80 offers 2513.3 N at 0.5 MPa; as the largest standard size, there is no larger SDA option. When ordering, confirm the 35 mm stroke, PT3/8 port, male M26x1.5 rod thread, and the integrated magnet. Keep in mind that a standard cylinder drifts when air pressure is lost or the valve is centered—the fixed bumper only decelerates near stroke end, so an external rod lock or pilot-operated check valve is required to hold a load safely.
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 SDA100X35SB FAQ
This 100 mm bore double-acting cylinder generates 3927 N push and 3524.9 N pull at 0.5 MPa. At 0.7 MPa, it produces 5497.8 N push and 4934.8 N pull. The theoretical maximum push force is 801 kgf at 1.0 MPa.
No, the piston will drift if air is lost or the valve is centered. The fixed NBR bumper only decelerates the rod near stroke end and does not act as a lock or brake. To maintain position on a vertical load, you must install an external rod lock or a pilot-operated check valve.
