Airtac SAU Standard Air Cylinder SAU80X5S
The AirTAC Airtac SAU Standard Air Cylinder SAU80X5S is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 5mm 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 SAU80X5S
The AirTAC SAU80X5S is a double-acting profile-type cylinder with an ultra-short 5 mm stroke. Its extruded aluminum barrel makes it more compact than an ISO 15552 cylinder of the same bore, fitting heavy-duty automation into tight machine envelopes. It delivers a push force of 2513 N at 0.5 MPa and a theoretical maximum of 513 kgf at 1.0 MPa.
Featuring a 3/8" port and a 25 mm piston rod, this unit includes a built-in magnet (-S) for direct mounting of CMSG, DMSG, or EMSG sensors along the profile groove. For practical sizing, plan for a safe working load of about 1508 N at 0.5 MPa to account for seal friction. This equates to lifting roughly 128 kg vertically with a 2:1 safety margin. You can also specify Viton H seals for high-temperature environments up to 150 C.

Where the Airtac SAU Standard Air Cylinder SAU80X5S Is Used
Stamping Pin Actuation
Drives a short-stroke marking pin in an automotive chassis line, delivering 2513 N of impact force to indent serial numbers into hardened steel brackets.
Heavy Part Ejection
Ejects dense machined aluminum transmission housings from a machining center conveyor, utilizing the 5 mm stroke to clear the part without overshooting the fixture.
Pallet Stopper Block
Acts as a high-force end-stop for loaded pallets entering a stretch wrapper, halting up to 128 kg of vertical load equivalent instantly without complex linkages.
Is the Airtac SAU Standard Air Cylinder SAU80X5S the Right Cylinder?
When sizing this unit, compare it against adjacent bores: the 63 mm bore provides 1559 N push at 0.5 MPa, while the 100 mm bore offers 3927 N. This 80 mm model fits perfectly when you need substantial force in a minimal travel distance. Because the -S suffix denotes an integrated magnet, you can easily track this short stroke with electronic or reed switches.
Keep in mind that a standard 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 only decelerate the piston near the stroke ends and do not function as a braking mechanism. To suspend a load safely, integrate an external rod lock or a pilot-operated check valve into your pneumatic circuit.
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 SAU80X5S FAQ
This 80 mm bore cylinder features a 3/8" port and a 25 mm rod. It generates a push force of 2513 N and a pull force of 2268 N at 0.5 MPa. At 0.7 MPa, the push force is 3518 N. The theoretical maximum force is 513 kgf at 1.0 MPa.
No, this is a profile-type cylinder and is not dimensionally interchangeable with ISO 15552 standards. It is designed to share mounting accessories with the AirTAC SC series, such as LB foot, FA/FB flange, and CA/CB clevis brackets. The -S magnet allows the use of CMSG, DMSG, and EMSG sensors.
