Airtac SAU Standard Air Cylinder SAU80X130S
The AirTAC Airtac SAU Standard Air Cylinder SAU80X130S is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 130mm stroke, 3/8" air ports and adjustable end cushioning. Its hard-anodized aluminum-profile barrel is shorter than an ISO 15552 cylinder of the same bore, and it shares SC-series mounting accessories.

About the Airtac SAU Standard Air Cylinder SAU80X130S
The AirTAC SAU80X130S is a double-acting profile-type cylinder with an 80 mm bore and 130 mm stroke. It delivers 2513 N of push force and 2268 N of pull force at 0.5 MPa, making it suitable for heavy-duty automation. Its extruded aluminum barrel with an integrated sensor groove makes it shorter and more compact than an ISO 15552 cylinder of the same bore, saving valuable machine space without sacrificing power. The 3/8" port and M20x1.5 rod thread ensure robust pneumatic connections for high-flow demands.
Because this SKU includes the -S magnet, it directly supports CMSG, DMSG, and EMSG reed or electronic switches for precise end-of-stroke detection. For real-world sizing, plan for a safe working load of about 1508 N at 0.5 MPa to account for seal friction. In a vertical lift scenario, it can reliably raise a 128 kg mass with a 2:1 safety margin. If your environment exceeds the standard -20 to +70 C range, a Viton H high-temperature seal option extends operation up to 150 C.

Where the Airtac SAU Standard Air Cylinder SAU80X130S Is Used
Stamping Press Feed
Drives heavy material grippers in an automated metal stamping line, utilizing the 2513 N push force to advance thick steel coils through a straightener.
Pallet Dispenser
Pushes empty pallets into a conveyor loading zone, where the 128 kg vertical lift capacity easily manages heavy wooden pallet stacks.
Injection Mold Ejection
Actuates a heavy secondary ejection arm on a large plastic injection molding machine, relying on the compact profile to fit within tight clamping areas.
Is the Airtac SAU Standard Air Cylinder SAU80X130S the Right Cylinder?
When sizing this 80 mm bore model, check the neighboring bores to ensure optimal performance: the 63 mm variant offers 1559 N push at 0.5 MPa, while the 100 mm variant provides 3927 N. This SAU80X130S fits perfectly in the middle for applications requiring approximately 2513 N. It shares mounting accessories with the AirTAC SC series, allowing you to use LB foot mounts, FA/FB flanges, or CA/CB clevises. The integrated -S magnet enables seamless sensor placement along the profile groove.
Remember 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 adjustable 28 mm air cushions at both ends only decelerate the piston near the stroke ends to prevent impact damage—they do not function as a locking brake. To suspend a load safely, install an external rod lock or a pilot-operated check valve.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
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 piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB — same as SC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAU Standard Air Cylinder SAU80X130S FAQ
At 0.5 MPa, the push force is 2513 N and the pull force is 2268 N. At 0.7 MPa it pushes 3518 N, and at 0.9 MPa it pushes 4523 N. The theoretical maximum force is 513 kgf at 1.0 MPa. Operating pressure ranges from 0.15-1.0 MPa, with a proof pressure of 1.5 MPa. The 3/8" port and 28 mm adjustable air cushions ensure smooth operation across the 30-800 mm/s speed range.
You cannot use ISO 15552 accessories, as the SAU is a distinct compact profile cylinder, not an ISO standard model. However, it shares mounting dimensions with the AirTAC SC series, so LB foot, FA/FB flange, and CA/CB clevis brackets fit perfectly. Because this SAU80X130S includes the -S magnet, you can mount CMSG, DMSG, or EMSG sensors directly into the extruded barrel groove.
