Airtac SAU Standard Air Cylinder SAU80X220
The AirTAC Airtac SAU Standard Air Cylinder SAU80X220 is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 220mm 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 SAU80X220
The AirTAC SAU80X220 is a double-acting profile-type cylinder featuring a 220 mm stroke and an extruded aluminum barrel. Because it is shorter than an ISO 15552 cylinder of the same bore, it provides a significant space advantage in tight machine layouts. It delivers a 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 piston rod and M20x1.5 rod thread.
For practical sizing, plan for a safe working load of about 1508 N at 0.5 MPa, accounting for seal friction and smooth travel. This translates to lifting roughly 128 kg vertically with a 2:1 safety margin, helping you match the cylinder to real part weights. This SKU lacks the -S magnet, so it cannot accept CMSG, DMSG, or EMSG sensor switches. If your application runs hot, you can opt for Viton H seals to raise the operating temperature from -20 to +70 C up to 0-150 C.

Where the Airtac SAU Standard Air Cylinder SAU80X220 Is Used
Injection Mold Clamping
Applies 2513 N of push force at 0.5 MPa to secure medium-sized injection mold halves, utilizing the 220 mm stroke to clear the tooling during part ejection.
Pallet Diverting
Pushes heavy product pallets off a high-speed packaging line, relying on the 28 mm adjustable air cushions to smoothly decelerate the 80 mm piston at stroke end.
Heavy Crate Ejector
Uses the safe working load of 1508 N to eject filled shipping crates from a roller conveyor, taking advantage of the compact profile length to fit between tight rollers.
Is the Airtac SAU Standard Air Cylinder SAU80X220 the Right Cylinder?
When sizing this 80 mm bore, stepping down to a 63 mm bore yields 1559 N of push force at 0.5 MPa, while stepping up to a 100 mm bore provides 3927 N. This SAU80X220 model shares its mounting accessories entirely with the AirTAC SC series, allowing you to use LB foot mounts, FA/FB flanges, CA/CB clevises, or I/Y/F/U rod knuckles. Since this is a 220 mm stroke, it remains well within standard length limits, but always ensure rigid guidance to prevent rod bending under heavy lateral loads. Note that a standard cylinder drifts when air is lost or the valve is centered; the 28 mm adjustable air cushions at both ends only decelerate the piston near stroke end and do not function as a braking lock. To suspend a load safely, integrate 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 SAU80X220 FAQ
The SAU80X220 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 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 a 25 mm piston rod with an M20x1.5 thread.
You cannot use ISO 15552 brackets, as the SAU is a compact profile cylinder that shares mounting accessories exclusively with the AirTAC SC series (such as LB, FA, FB, CA, CB). Additionally, because this specific SKU lacks the -S magnet suffix, it cannot accept CMSG, DMSG, or EMSG magnetic switches.
