About the Airtac SDA Ultra Thin Cylinder SDA100X20
The AirTAC SDA100X20 is a double-acting single-rod compact cylinder engineered for heavy-duty tasks within a minimal axial footprint. It delivers a substantial 3927 N push and 3524.9 N pull at 0.5 MPa, reaching a theoretical maximum push of 801 kgf at 1.0 MPa. The hard-anodized 100 mm bore and two-way piston seal ensure durability, while the PT3/8 air ports supply the volume needed for high-force operation.
This model features a 32 mm piston rod and a 20 mm stroke, utilizing a short riveted body that saves mounting depth where a traditional round-body cylinder will not fit. End-of-stroke deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion. Because this specific SKU lacks the -S magnet option, it cannot directly host AirTAC reed or electronic switches.

Where the Airtac SDA Ultra Thin Cylinder SDA100X20 Is Used
Stamping Press Ejection
Provides the heavy 3927 N push force required to knock thick steel blanks out of a progressive die in a confined mechanical press footprint.
Injection Mold Clamping
Applies high clamping pressure to hold heavy mold halves together securely, utilizing the short 20 mm stroke to save axial machine depth.
Heavy Gauge Metal Forming
Delivers the rigid 32 mm rod thrust necessary for bending thick structural brackets, relying on the 801 kgf maximum capacity for severe deformation.
Is the Airtac SDA Ultra Thin Cylinder SDA100X20 the Right Cylinder?
When sizing this actuator, stepping down to the SDA80 provides 2513.3 N of push at 0.5 MPa, whereas this 100 mm bore tops out the series at 3927 N at the same pressure, offering maximum thrust for the SDA family. A safe working load is approximately 2356 N (about 60% of the 0.5 MPa figure), allowing a vertical lift of roughly 200.2 kg with a 2:1 safety margin. To order, confirm the 100 mm bore, 20 mm stroke, PT3/8 port, female M18x1.5 rod thread, and the absence of a sensor magnet.
Keep in mind that a standard compact cylinder does not hold its load if air pressure is lost or the directional valve is centered; the piston will drift, and the fixed NBR bumper only decelerates the stroke end rather than locking it. If your application must maintain position without live pressure, an external rod lock or a pilot-operated check valve is required.
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 SDA100X20 FAQ
At 0.5 MPa, this 100 mm bore double-acting cylinder provides 3927 N of push and 3524.9 N of pull. At 0.7 MPa, push increases to 5497.8 N and pull to 4934.8 N. The theoretical maximum push is 801 kgf at 1.0 MPa, and the maximum standard stroke available for this bore is 130 mm.
This specific SKU lacks the -S piston magnet, so it cannot host reed or electronic switches. Additionally, end-stop deceleration relies solely on a fixed NBR bumper, which is not an adjustable air cushion; for high-energy impacts at 30-500 mm/s, add an external shock absorber.
