About the Airtac SDA Ultra Thin Cylinder SDA80X20
The AirTAC SDA80X20 is a double-acting single-rod compact cylinder engineered to deliver a substantial 2513.3 N push force at 0.5 MPa. Its riveted assembly unites the barrel, rear cover, piston, and rod into a remarkably short axial footprint, saving valuable machine depth where a conventional round-body unit would never fit. The bore is hard-anodized and utilizes a two-way piston seal for reliable performance.
This specific configuration features a 25 mm piston rod and a 20 mm stroke, making it ideal for high-force, short-travel tasks. End-of-travel deceleration is handled 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-energy loads. Note that this SKU lacks a piston magnet, so it cannot host position sensing without upgrading to the -S variant.

Where the Airtac SDA Ultra Thin Cylinder SDA80X20 Is Used
Press Fit Bushings
Drives short 20 mm insertion strokes to seat metal bushings into automotive gearbox housings, utilizing the 2513.3 N push force to overcome heavy interference fits.
Injection Mold Clamping
Secures lightweight plastic injection mold halves within tight machinery frames, leveraging the short riveted body to minimize axial footprint on the platen.
Staking Rivets
Applies localized 128 kg vertical pressure to stake aluminum rivets in consumer electronics chassis assembly, ensuring consistent joint formation without crushing components.
Is the Airtac SDA Ultra Thin Cylinder SDA80X20 the Right Cylinder?
When sizing this unit, evaluate your force requirements carefully. Stepping down to the SDA63 yields 1558.6 N of push at 0.5 MPa, whereas stepping up to the SDA100 provides 3927 N. The SDA80X20 strikes a balance, offering a safe working load of roughly 1508 N (about 60% of its 0.5 MPa capacity) and a vertical lift capability of approximately 128.1 kg with a 2:1 safety margin.
For ordering, confirm the 80 mm bore, 20 mm stroke, and PT3/8 port. This base model has no magnet and a female M14x1.5 rod end thread. Remember that a standard compact cylinder drifts if air pressure is lost or the valve is centered; the fixed bumper only decelerates near stroke end and acts as neither a lock nor a brake. To suspend a load safely without live pressure, integrate an external rod lock or a pilot-operated check valve.
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 SDA80X20 FAQ
At 0.5 MPa, this double-acting cylinder provides 2513.3 N of push and 2267.8 N of pull. At 0.7 MPa, push increases to 3518.6 N and pull to 3175 N. The theoretical maximum push is 513 kgf at 1.0 MPa. It operates between 0.15 and 1.0 MPa, with a proof pressure of 1.5 MPa, and runs at speeds of 30-500 mm/s.
No, this specific SKU does not include a piston magnet, so it cannot host a reed or electronic switch. To enable position sensing, you must select the SDA80X20S variant, which adds a built-in magnet compatible with AirTAC sensors mounted in the body grooves.
