About the Airtac SDA Ultra Thin Cylinder SDA100X100S
The AirTAC SDA100X100S is a double-acting, single-rod compact cylinder engineered to deliver substantial thrust within a minimal axial footprint. By utilizing a riveted assembly that integrates the barrel, rear cover, piston, and rod, this unit achieves an overall length far shorter than conventional round-body actuators. At 100 mm bore, it generates 3927 N of push force and 3524.9 N of pull force at 0.5 MPa, making it suitable for heavy-duty positioning tasks.
This specific model includes a built-in piston magnet (designated by the S code) for use with AirTAC reed or electronic switches, which seat cleanly into the machined grooves around the body. The 32 mm piston rod features a female M18x1.5 thread for load coupling, and the air supply connects via PT3/8 ports. End-of-stroke deceleration is handled by a fixed NBR bumper rather than an adjustable cushion, meaning high-energy cycles may require an external shock absorber to prevent impact wear.

Where the Airtac SDA Ultra Thin Cylinder SDA100X100S Is Used
Injection Mold Ejection
Drives heavy mold ejection plates in plastics manufacturing, utilizing the 3927 N push force to reliably strip dense parts from tooling cavities.
Metal Stamping Feed
Acts as a robust positioning stop for heavy-gauge steel coil feeding in stamping presses, where the short riveted body conserves floor space.
Pallet Lifter Alignment
Indexes heavy palletized loads on packaging lines, depending on the 3524.9 N pull force to retract the 32 mm rod against gravitational resistance.
Is the Airtac SDA Ultra Thin Cylinder SDA100X100S the Right Cylinder?
Selecting this 100 mm bore actuator involves sizing both ways to match your exact load requirements. Stepping down, the SDA80 provides 2513.3 N of push force at 0.5 MPa, serving as a lighter alternative if your application does not demand the full 3927 N output. Stepping up is not possible within the SDA series as this represents the maximum bore size, so for loads exceeding the 801 kgf theoretical maximum at 1.0 MPa, a larger profile format would be required. A useful computed insight for this model is a safe working load of approximately 2356 N, representing about 60% of the 0.5 MPa push figure, which translates to a vertical lift capacity of roughly 200.2 kg when applying a 2:1 safety margin.
When integrating this cylinder, remember that a plain double-acting design does not hold its position if air pressure is lost or the valve is centered; the piston will drift, and the fixed NBR bumper only decelerates the rod near the stroke end without acting as a mechanical lock. For applications requiring suspended load holding, an external rod lock or pilot-operated check valve must be added. To finalize your order, confirm the 100 mm bore, 100 mm stroke, PT3/8 porting, the S magnet option, and the female M18x1.5 rod thread.
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 SDA100X100S FAQ
This double-acting cylinder 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 and the pull to 4934.8 N. The theoretical maximum push is 801 kgf at the maximum operating pressure of 1.0 MPa.
No, a plain SDA cylinder will drift if air is lost or the valve is centered. The fixed NBR bumper only decelerates the piston near the stroke end and does not function as a braking lock. To maintain a vertical load without live pressure, you must install an external rod lock or a pilot-operated check valve.
