About the Airtac SDA Ultra Thin Cylinder SDA80X30
The AirTAC SDA80X30 is a double-acting, single-rod compact cylinder engineered to deliver a robust 2513.3 N push force at 0.5 MPa. Its defining characteristic is a short, riveted body that integrates the barrel, rear cover, piston, and rod into a single highly condensed unit. This space-saving architecture drastically reduces axial mounting depth compared to traditional round-body cylinders, making it ideal for heavy-duty machinery with tight footprint constraints.
Built for demanding cycles, this 80 mm bore model features a 25 mm piston rod and PT3/8 air ports. End-stop energy is managed strictly by a fixed NBR bumper rather than an adjustable air cushion, meaning operators should slow the approach or add an external shock absorber for high kinetic loads. This specific SKU lacks the internal piston magnet, so it cannot host magnetic position switches without upgrading to the -S variant.

Where the Airtac SDA Ultra Thin Cylinder SDA80X30 Is Used
Injection Mold Ejection
Provides the heavy 2513.3 N push stroke required to knock finished plastic parts out of tight mold tooling spaces where full-length profile cylinders cannot fit.
Metal Stamping Press Feed
Handles robust workpiece alignment and clamping at 0.5 MPa inside compact press enclosures, utilizing the 25 mm rod to resist deflection during heavy gauge material indexing.
Palletizer Lift Station
Drives short 30 mm vertical lifting motions for heavy payload stops, relying on the fixed NBR bumper to absorb the end-stop impact without requiring extensive axial clearance.
Is the Airtac SDA Ultra Thin Cylinder SDA80X30 the Right Cylinder?
When sizing this actuator, evaluate your force requirements carefully. Stepping down to the SDA63 yields 1558.6 N of push at 0.5 MPa, while moving up to the SDA100 provides 3927 N. The SDA80X30 offers a safe working load of roughly 1508 N (about 60% of its 0.5 MPa capacity) and can vertically lift approximately 128.1 kg with a 2:1 safety margin. Confirm your ordering essentials: 80 mm bore, 30 mm stroke, PT3/8 port, female M14x1.5 rod thread, and no sensor magnet.
Remember that a standard compact actuator cannot hold a load if air pressure drops or the directional valve is centered. The piston will drift, and the fixed NBR bumper only decelerates the stroke near its end without acting as a mechanical brake. If your application demands fail-safe position holding, 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 SDA80X30 FAQ
At 0.5 MPa, the push force is 2513.3 N and the pull force is 2267.8 N. At 0.7 MPa, the push force is 3518.6 N. The theoretical maximum push force is 513 kgf at 1.0 MPa. The operating pressure range is 0.15-1.0 MPa, with a proof pressure of 1.5 MPa, and the operating speed ranges from 30-500 mm/s.
No, this specific SDA80X30 SKU does not include the internal piston magnet, so it cannot host AirTAC reed or electronic switches. You would need to specify the -S option (SDA80X30S) to enable magnetic position sensing. Additionally, the end caps use a fixed NBR bumper for deceleration, not an adjustable air cushion.
