Airtac SAU Standard Air Cylinder SAU80X450S
The AirTAC Airtac SAU Standard Air Cylinder SAU80X450S is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 450mm 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 SAU80X450S
The AirTAC SAU80X450S is a double-acting profile-type cylinder with a 450 mm stroke and an extruded aluminum barrel. Its integrated design makes it shorter than an ISO 15552 cylinder of the same 80 mm bore, saving valuable machine space. It delivers a robust 2513 N of push force and 2268 N of pull force at 0.5 MPa, operating through a 3/8 inch port and a 25 mm rod with an 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 translates to lifting roughly 128 kg vertically with a 2:1 safety margin. The -S suffix means a piston magnet is included, allowing you to mount CMSG, DMSG, or EMSG sensors directly into the barrel groove. You can also pair it with AirTAC SC-series mounting accessories like LB foot brackets or CA clevises, and select Viton H seals if your environment reaches 150 C.

Where the Airtac SAU Standard Air Cylinder SAU80X450S Is Used
Injection Mold Ejection
Drives heavy mold ejection plates over the 450 mm travel, utilizing the 2513 N push force to reliably strip dense plastic parts from tooling cavities.
Pallet Dispenser Pusher
Indexes empty pallets into a packaging line, where the compact profile length prevents interference with adjacent conveyor frames during the long extension.
Heavy Crate Diversion
Actuates a diverter arm to route heavy freight crates, depending on the integrated magnet and DMSG sensors to confirm full stroke completion.
Is the Airtac SAU Standard Air Cylinder SAU80X450S the Right Cylinder?
When sizing this 80 mm bore, stepping down to a 63 mm cylinder drops the 0.5 MPa push force to 1559 N, while stepping up to a 100 mm bore increases it to 3927 N. Because this is a 450 mm stroke, you must account for side-load risks and rod-bending moments; always use an external guide rail to support the load and prevent premature seal wear. The adjustable 28 mm air cushions at both ends help decelerate the piston smoothly, but they do not function as a brake. If air pressure is lost or the valve is centered, the rod will drift, so install an external rod lock or a pilot-operated check valve for secure load holding.
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 SAU80X450S FAQ
This 80 mm bore cylinder provides 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, and a theoretical maximum of 513 kgf at 1.0 MPa. It operates between 0.15-1.0 MPa, runs at 30-800 mm/s, and features a 3/8 inch port with a 25 mm rod.
It shares mounting accessory compatibility with the AirTAC SC series (such as FA flanges and CB clevises) but is not an ISO 15552 cylinder and has a shorter footprint. The -S suffix indicates a built-in magnet, enabling CMSG, DMSG, or EMSG switches to fit directly into the profile barrel groove.
