About the Airtac SDA Ultra Thin Cylinder SDA100X25SN
The AirTAC SDA100X25SN is a double-acting single-rod compact cylinder engineered to deliver substantial force within a minimal axial footprint. It generates 3927 N of push force and 3524.9 N of pull force at 0.5 MPa, making it suitable for heavy-duty short-stroke tasks. The riveted assembly integrates the barrel, rear cover, piston, and rod to drastically reduce overall length compared to conventional round-body units.
This 100mm bore model incorporates a built-in piston magnet for compatibility with AirTAC reed or electronic switches, fitting directly into the body grooves. End-of-travel deceleration is handled by a fixed NBR bumper rather than an adjustable cushion, and the hard-anodized bore ensures long service life. The unit features a 32mm piston rod and a PT3/8 port.

Where the Airtac SDA Ultra Thin Cylinder SDA100X25SN Is Used
Stamping Press Ejection
Provides the high 3927 N push force required to eject heavy metal blanks from a stamping press bed in a short 25mm motion.
Injection Mold Parting
Handles the robust separation force needed to break loose large plastic injection molds, utilizing the compact riveted body to fit tight mold platen areas.
Heavy Pallet Positioning
Lifts or indexes loaded pallets weighing up to 200.2 kg vertically with a safe 2:1 margin, relying on the 32mm rod for structural stability.
Is the Airtac SDA Ultra Thin Cylinder SDA100X25SN the Right Cylinder?
When sizing this actuator, evaluate your force requirements carefully. Stepping down to the SDA80 provides 2513.3 N of push at 0.5 MPa, which may suffice for lighter loads, whereas this 100mm bore reaches the series maximum of 801 kgf at 1.0 MPa. With a 2:1 safety margin, the vertical lift capacity is approximately 200.2 kg, equating to a safe working load around 2356 N. Keep in mind that a standard double-acting cylinder drifts when air pressure is lost or the valve is centered; the fixed bumper only slows the piston near stroke end and does not function as a locking brake. If your application requires position holding without live pressure, install an external rod lock or a pilot-operated check valve.
To finalize your order, confirm the 100mm bore, 25mm stroke, PT3/8 port, female M18x1.5 rod-end thread, and the built-in magnet option. The maximum standard stroke for this bore is 130mm.
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 SDA100X25SN FAQ
This 100mm bore double-acting cylinder has a PT3/8 air port. The force output is 3927 N push and 3524.9 N pull at 0.5 MPa, 5497.8 N push and 4934.8 N pull at 0.7 MPa, with a theoretical maximum push of 801 kgf at 1.0 MPa.
No, it uses a fixed NBR bumper at each end to decelerate the stroke, which is not a field-adjustable air cushion. Additionally, it does not lock or hold the load if air pressure drops; the piston will drift. For high-speed impacts, add an external shock absorber, and use a pilot-operated check valve if load holding is required.
