Airtac SDA Ultra Thin Cylinder SDA100X25B
The AirTAC Airtac SDA Ultra Thin Cylinder SDA100X25B is a genuine double-acting COMPACT (thin) air cylinder with a Ø100mm bore and 25mm stroke, PT3/8 air ports and a riveted short body that saves mounting depth. Sensor slots around the body accept magnetic switches for position sensing.

About the Airtac SDA Ultra Thin Cylinder SDA100X25B
The AirTAC SDA100X25B is a double-acting single-rod compact cylinder engineered for high-force actuation within a minimal axial footprint. Its riveted body assembly significantly reduces mounting depth compared to conventional round-body units, delivering a substantial 3927 N push at 0.5 MPa. The hard-anodized 100mm bore operates with a two-way piston seal, and this specific configuration features a robust 32mm piston rod with an M26x1.5 male thread for secure load coupling.
This model relies on a fixed NBR bumper at each end to decelerate the stroke end rather than an adjustable air cushion. Because this SKU lacks the -S magnet option, it cannot directly mount AirTAC reed or electronic switches. Operating at speeds of 30-500 mm/s, the short 25mm stroke excels in heavy-duty clamping or ejection tasks where space is restricted and high impact energy is present.

Where the Airtac SDA Ultra Thin Cylinder SDA100X25B Is Used
Metal Stamping Ejection
Provides the intense 3927 N push force required to eject heavy stamped metal panels from progressive die sets in a confined press footprint.
Injection Mold Clamping
Utilizes the 25mm short stroke and M26x1.5 male rod to lock auxiliary mold cores in place during high-pressure plastic injection molding cycles.
Heavy Gauge Brake Forming
Applies localized holding pressure on thick steel plates within an CNC press brake, leveraging the 100mm bore capacity where axial depth is severely limited.
Is the Airtac SDA Ultra Thin Cylinder SDA100X25B the Right Cylinder?
When sizing this 100mm bore actuator, stepping down to the SDA80 yields a 2513.3 N push at 0.5 MPa, whereas this SDA100X25B provides 3927 N at the same pressure, representing the maximum standard thrust in the series. For load verification, a safe working load is approximately 2356 N (about 60% of the 0.5 MPa figure), translating to a vertical lift capacity of roughly 200.2 kg with a 2:1 safety margin. Ensure you specify the PT3/8 port, the 25mm stroke, and the male M26x1.5 rod thread when ordering.
Keep in mind that a standard double-acting cylinder does not hold its position if air pressure drops or the valve is centered; the piston will drift, and the fixed NBR bumper only decelerates near the stroke end without acting as a mechanical lock. If your application requires strict load holding on air loss, you must integrate an external rod lock or a pilot-operated check valve into the pneumatic circuit.
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 SDA100X25B FAQ
The SDA100X25B generates 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 is 801 kgf at the maximum operating pressure of 1.0 MPa.
No, this model uses a fixed NBR bumper to decelerate at the stroke ends and does not have an adjustable air cushion. Additionally, because it lacks the -S magnet option, it cannot support AirTAC reed or electronic switches. For high-energy impacts, consider adding external shock absorbers.
