Airtac SAU Standard Air Cylinder SAU80X750S
The AirTAC Airtac SAU Standard Air Cylinder SAU80X750S is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 750mm 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 SAU80X750S
The AirTAC SAU80X750S is a double-acting profile-type cylinder with a 80 mm bore and 750 mm stroke. It features an extruded aluminum barrel with an integrated sensor groove, making it shorter and more compact than an ISO 15552 cylinder of the same bore. It delivers a robust push force of 2513 N and a pull force of 2268 N at 0.5 MPa, operating on a 3/8" port with a 25 mm rod and M20x1.5 thread.
For practical sizing, plan for a safe working load of about 1508 N at 0.5 MPa to account for seal friction and smooth travel. This equates to lifting roughly 128 kg vertically with a 2:1 safety margin. The -S suffix indicates a built-in piston magnet, enabling direct mounting of CMSG, DMSG, or EMSG switches in the profile groove for precise end-position detection. A Viton H seal option can elevate the operating temperature range from the standard -20 to +70 C up to 0-150 C for high-heat environments.

Where the Airtac SAU Standard Air Cylinder SAU80X750S Is Used
Pallet Transfer Diversion
Pushes heavy loaded pallets sideways onto secondary conveyor lines, utilizing the 2513 N push force to overcome friction over the 750 mm travel distance.
Vertical Lift Gate
Raises and lowers mezzanine safety gates, where the compact profile saves headroom and the 128 kg vertical lift capacity easily handles heavy steel framing.
Injection Mold Ejection
Drives a secondary ejection arm to clear large molded parts from a press, relying on the -S magnet and DMSG switches to confirm full extension.
Is the Airtac SAU Standard Air Cylinder SAU80X750S the Right Cylinder?
When sizing this 80 mm bore, compare it directly with its neighbors: the 63 mm bore offers 1559 N push at 0.5 MPa, while the 100 mm bore provides 3927 N. If your application demands higher force, step up to the 100 mm; if 2513 N is excessive, the 63 mm is your alternative. Mounting is straightforward using AirTAC SC-series accessories, including LB foot, FA/FB flange, and CA/CB clevis brackets, alongside various I, Y, F, or U rod knuckles.
Because this unit features a 750 mm stroke, you must account for side-load and rod-bending risks—always use an external guide rail to support the load and prevent premature seal wear. Note that a standard SAU 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 act as a braking mechanism. For suspended or vertical loads, 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 SAU80X750S FAQ
The 80 mm bore provides 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, and at 0.9 MPa it is 4523 N. The theoretical maximum force is 513 kgf at 1.0 MPa. It uses a 3/8" air port and operates at speeds between 30-800 mm/s.
It is not an ISO 15552 cylinder, but it is shorter and more compact than ISO standards while sharing mounting accessories with the AirTAC SC series (LB, FA, FB, CA, CB). The -S suffix means it has a built-in magnet for CMSG, DMSG, or EMSG sensors that fit directly into the barrel's sensor groove.
