Airtac SAU Standard Air Cylinder SAU80X900S
The AirTAC Airtac SAU Standard Air Cylinder SAU80X900S is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 900mm 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 SAU80X900S
The AirTAC SAU80X900S is a double-acting profile-type cylinder featuring an extruded aluminum barrel with an integrated sensor groove. Designed to be more compact than an ISO 15552 cylinder of the same bore, it saves valuable machine space while delivering substantial force. It provides a push force of 2513 N and a pull force of 2268 N at 0.5 MPa, operating via a 3/8 inch port and a 25 mm rod with an M20x1.5 thread.
Equipped with a piston magnet (-S), this unit supports CMSG, DMSG, and EMSG switches for precise position detection. For practical sizing, plan for a safe working load of about 1508 N at 0.5 MPa to account for seal friction. In vertical lifting applications, it can handle roughly 128 kg with a 2:1 safety margin. If your environment exceeds standard limits, a Viton H seal option extends the operating temperature range from 0 to 150 C.

Where the Airtac SAU Standard Air Cylinder SAU80X900S Is Used
Pallet Transfer Line
Pushes heavy loaded pallets between processing stations using its 2513 N push force at 0.5 MPa, while the compact profile saves floor space.
Vertical Material Lift
Elevates components weighing up to 128 kg in a high-bay storage system, relying on the 900 mm stroke to reach distinct shelf levels.
Automated Press Feed
Actuates a 900 mm feed mechanism to push metal blanks into a stamping press, utilizing the 3/8 inch port for rapid air exchange.
Is the Airtac SAU Standard Air Cylinder SAU80X900S the Right Cylinder?
When sizing this 80 mm bore unit, consider stepping down to the 63 mm bore (push 1559 N at 0.5 MPa) for lighter loads, or up to the 100 mm bore (push 3927 N at 0.5 MPa) for heavier demands. The 900 mm stroke requires careful attention to side-load and rod-bending risks; always use an external guide rail to prevent premature wear. This model shares its mounting footprint with AirTAC SC-series accessories, including LB foot, FA/FB flange, and CA/CB clevis options. Note that the adjustable air cushion only decelerates the piston near stroke end; it does not function as a brake. To prevent drift from gravity or air loss, 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 SAU80X900S FAQ
This 80 mm bore cylinder features a 3/8 inch port and delivers 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 the theoretical maximum force is 513 kgf at 1.0 MPa.
Yes, the -S suffix indicates a built-in piston magnet, allowing you to install CMSG, DMSG, or EMSG switches directly into the barrel groove. For installation, it uses the same mounting accessories as the AirTAC SC series, such as LB foot, FA/FB flange, and CA/CB clevis brackets.
