About the Airtac SDA Ultra Thin Cylinder SDA80X35
The AirTAC SDA80X35 is a double-acting, single-rod compact cylinder engineered to deliver a robust 2513.3 N push force at 0.5 MPa. Its riveted assembly joins the barrel, rear cover, piston, and 25 mm rod into a highly abbreviated unit, drastically reducing axial mounting depth compared to conventional round-body actuators. This space efficiency is critical when designing large-bore actuation into tight machine footprints.
This specific configuration features a 35 mm stroke and a PT3/8 port. Instead of an adjustable air cushion, the piston strikes a fixed NBR bumper at each end to decelerate the stroke. Because this SKU lacks the S option, it has no piston magnet and cannot support position sensing; adding the -S variant enables the use of reed or electronic switches in the body grooves.

Where the Airtac SDA Ultra Thin Cylinder SDA80X35 Is Used
Injection Mold Ejection
Provides the high 2513.3 N push force required to eject dense plastic parts from injection molding tools where short overall length prevents interference with the press platen.
Heavy Press Brake Gauging
Positions back-gauge stops on heavy sheet metal press brakes, utilizing the 25 mm rod to withstand substantial lateral resistance during plate alignment.
Pallet Flap Folding
Folds heavy cardboard flaps on automated palletizing lines, delivering rapid 35 mm strokes that cycle continuously at speeds between 30 and 500 mm/s.
Is the Airtac SDA Ultra Thin Cylinder SDA80X35 the Right Cylinder?
When sizing this 80 mm bore actuator, evaluate your force requirements carefully. Stepping down, the SDA63 provides 1558.6 N of push at 0.5 MPa, while stepping up to the SDA100 yields 3927 N at the same pressure. For the SDA80X35, a safe working load is approximately 1508 N (60% of the 0.5 MPa figure), translating to a vertical lift capacity of about 128.1 kg with a 2:1 safety margin.
Remember that a standard double-acting cylinder drifts when air pressure is lost or the valve is centered, as the fixed bumper only decelerates the piston near stroke end rather than locking it. To hold a load securely without live pressure, you must integrate an external rod lock or a pilot-operated check valve. To order, confirm the 80 mm bore, 35 mm stroke, PT3/8 port, female M14x1.5 rod thread, and the absence of a magnet.
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 SDA80X35 FAQ
This 80 mm bore double-acting cylinder generates 2513.3 N of push and 2267.8 N of pull at 0.5 MPa. At 0.7 MPa, push increases to 3518.6 N. The theoretical maximum push force is 513 kgf at 1.0 MPa, with a proof pressure of 1.5 MPa.
No adjustable air cushion exists; the cylinder relies on fixed NBR bumpers to decelerate the stroke end, so external shock absorbers are advised for high-energy loads. Additionally, this specific SKU lacks a piston magnet, meaning it cannot accept reed or electronic switches unless upgraded to the S option.
