About the Airtac SDA Ultra Thin Cylinder SDA100X25SB
The AirTAC SDA100X25SB is a double-acting, single-rod compact cylinder engineered for heavy-duty automation within a minimal axial footprint. Utilizing a riveted body assembly, it achieves a remarkably short overall length compared to conventional round-body actuators, saving valuable machine mounting depth. At 100 mm bore, this unit generates a substantial 3927 N push force at 0.5 MPa, supported by a robust Ø32 mm piston rod.
This specific configuration includes the -S option for a built-in piston magnet, enabling seamless integration with AirTAC reed or electronic switches via the body's peripheral grooves. The -B option provides a male M26x1.5 threaded rod end for secure mechanical load coupling. Deceleration is handled by a fixed NBR bumper at each end, which absorbs end-stop impact but is not a field-adjustable air cushion.

Where the Airtac SDA Ultra Thin Cylinder SDA100X25SB Is Used
Stamping Press Ejection
Provides the high 3927 N extension force needed to eject heavy formed metal panels from a stamping die, utilizing the short 25 mm stroke to minimize press body intrusion.
Injection Mold Separation
Delivers robust pulling power via its 3524.9 N retract force to break loose and separate large injection-molded plastic components from deep cavity molds.
Heavy Pallet Lifting
Lifts loaded pallets weighing up to 200.2 kg in packaging lines, where the male M26x1.5 rod end ensures a rigid, secure mechanical coupling to the lifting fork assembly.
Is the Airtac SDA Ultra Thin Cylinder SDA100X25SB the Right Cylinder?
Selecting this 100 mm bore actuator involves sizing both ways: stepping down to the SDA80 yields 2513.3 N push at 0.5 MPa, while this SDA100 provides 3927 N. With a safe working load around 2356 N (approximately 60% of the 0.5 MPa figure), it can vertically lift roughly 200.2 kg with a 2:1 safety margin. If your application requires holding a load vertically during air loss or valve centering, note that a plain cylinder drifts; an external rod lock or pilot-operated check valve is required. When ordering, confirm the 100 mm bore, 25 mm stroke, PT3/8 port, built-in magnet (S), and male M26x1.5 rod thread (B).
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 SDA100X25SB FAQ
This double-acting 100 mm bore cylinder provides a push force of 3927 N and a pull force of 3524.9 N at 0.5 MPa. At 0.7 MPa, the push increases to 5497.8 N. The theoretical maximum push force is 801 kgf at 1.0 MPa.
It uses a fixed NBR bumper at each end to absorb impact; this is not an adjustable air cushion, so external shock absorbers are recommended for high-speed approaches. The built-in magnet (-S) works with AirTAC reed or electronic switches mounted in the body grooves for position detection.
