About the Airtac SDA Ultra Thin Cylinder SDA100X15
The AirTAC SDA100X25 is a double-acting single-rod compact cylinder engineered for heavy-duty automation within a minimal axial footprint. It delivers a substantial 3927 N push force at 0.5 MPa and features a robust 32 mm piston rod. The riveted body design drastically reduces overall length compared to conventional round-body units, making it ideal for tight machine layouts.
This model relies on a fixed NBR bumper at each end to decelerate the stroke, meaning it is not an adjustable air cushion. Because this specific SKU lacks the -S option, it has no piston magnet and cannot support magnetic sensing. For applications requiring position feedback, the -S variant is necessary to accommodate reed or electronic switches.

Where the Airtac SDA Ultra Thin Cylinder SDA100X15 Is Used
Injection Mold Ejection
Provides high-force ejection of molded plastic parts from tight tooling cavities where the short 15 mm stroke and compact body depth prevent interference with the mold base.
Heavy-Duty Spot Welding
Applies 3927 N of clamping thrust at 0.5 MPa to hold thick steel sheets firmly in position during robotic spot welding operations within confined robotic cells.
Press Fit Assembly
Drives solid steel dowel pins into heavy machinery chassis, utilizing the 32 mm rod and massive 801 kgf maximum thrust capacity for secure mechanical joining.
Is the Airtac SDA Ultra Thin Cylinder SDA100X15 the Right Cylinder?
When sizing this unit, consider stepping down to the SDA80, which provides 2513.3 N push at 0.5 MPa for lighter loads, or utilize this 100 mm bore for maximum thrust. The computed safe working load is approximately 2356 N (about 60% of the 3927 N figure), allowing a vertical lift of roughly 200.2 kg with a 2:1 safety margin. Ensure your ordering essentials include the 100 mm bore, 15 mm stroke, PT3/8 port, female rod thread, and no magnet.
Keep in mind that a plain SDA cylinder does not hold its position or load when air pressure is lost or the valve is centered; the piston will drift. If your application requires a held load without live pressure, you must integrate an external rod lock or a pilot-operated check valve into your 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 SDA100X15 FAQ
This double-acting cylinder generates 3927 N push and 3524.9 N pull at 0.5 MPa, increasing to 5497.8 N push and 4934.8 N pull at 0.7 MPa. The theoretical maximum push force is 801 kgf at 1.0 MPa. It operates between 0.15-1.0 MPa, with a proof pressure of 1.5 MPa, and runs at speeds of 30-500 mm/s.
No, this model uses a fixed NBR bumper at each end to decelerate the stroke, which is not an adjustable air cushion. Additionally, this specific SKU lacks the -S magnet option, so it cannot support reed or electronic switches; you would need the -S variant for position sensing.
