About the Airtac SDA Ultra Thin Cylinder SDA40X10
The AirTAC SDA40X10 is a double-acting single-rod compact cylinder engineered for tight axial spaces. It delivers a push force of 628.3 N and a pull force of 527.8 N at 0.5 MPa, operating via a PT1/8 port. The riveted assembly merges the hard-anodized barrel, rear cover, and piston into an ultra-short unit, significantly reducing machine footprint compared to round-body alternatives.
This specific SKU features a 10 mm stroke and a 16 mm piston rod, but lacks a piston magnet, meaning it cannot support magnetic sensing. End-of-travel deceleration is handled strictly by fixed NBR bumpers rather than adjustable air cushions, ensuring reliable mechanical stops without external tuning.

Where the Airtac SDA Ultra Thin Cylinder SDA40X10 Is Used
Stamping Pin Ejection
Provides a rapid 10 mm ejection stroke of finished metal pins from a stamping die, utilizing the 628.3 N push force to overcome friction and clear the tooling for the next cycle.
Carton Flap Folding
Executes short, repetitive folding actions on packaging lines to tuck corrugated carton flaps prior to sealing, fitting neatly into compact machinery side frames.
Component Seating
Presses small bearings or bushings into housings on an automated assembly line, applying a controlled 527.8 N pull force to extract the ram after the part is seated.
Is the Airtac SDA Ultra Thin Cylinder SDA40X10 the Right Cylinder?
When sizing this actuator, evaluate your force margins carefully. Stepping down to the SDA32 yields 402.1 N of push force at 0.5 MPa, while moving up to the SDA50 provides 981.7 N. For the SDA40X10, a safe working load is approximately 377 N (about 60% of the 628.3 N capacity at 0.5 MPa), translating to a vertical lift capability of roughly 32 kg with a 2:1 safety margin. Ensure your ordering essentials match your assembly: this configuration specifies a 40 mm bore, 10 mm stroke, PT1/8 port, female rod-end thread (M8x1.25), and no sensor magnet. If position feedback is required, select the -S option for reed or electronic switch compatibility.
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. The fixed NBR bumper only decelerates the load near the stroke end and does not function as a locking brake. To maintain vertical loads safely during an air loss event, 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 SDA40X10 FAQ
The SDA40X10 generates a push force of 628.3 N and a pull force of 527.8 N at 0.5 MPa. At 0.7 MPa, the push force is 879.6 N. The theoretical maximum push force is 128 kgf at 1.0 MPa. It operates within a pressure range of 0.15-1.0 MPa, with a proof pressure of 1.5 MPa, and a speed range of 30-500 mm/s.
No, this model uses fixed NBR bumpers at each end to decelerate the stroke, which are not field-adjustable; for high-energy impacts, slow the approach or use an external shock absorber. Additionally, this specific SKU lacks a piston magnet, so it cannot accept AirTAC reed or electronic switches. You would need the SDA40X10S variant for position sensing.
