Airtac SAU Standard Air Cylinder SAU80X950S
The AirTAC Airtac SAU Standard Air Cylinder SAU80X950S is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 950mm 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 SAU80X950S
The AirTAC SAU80X950S is a double-acting profile-type cylinder featuring a 950 mm stroke and a 3/8 inch port. Its extruded aluminum barrel makes it shorter and more compact than an ISO 15552 cylinder of the same 80 mm bore, providing a distinct space advantage in tight machine layouts. It delivers a robust 2513 N push force at 0.5 MPa.
For practical sizing, plan for a safe working load of roughly 1508 N at 0.5 MPa, accounting for seal friction and smooth travel. Vertically, this translates to lifting about 128 kg with a 2:1 safety margin. The included -S magnet enables position sensing via CMSG, DMSG, or EMSG switches, while the 950 mm length requires external guides to prevent rod bending under side loads.

Where the Airtac SAU Standard Air Cylinder SAU80X950S Is Used
Pallet Transfer Line
Pushes heavy loaded pallets between conveyor sections using its 2513 N push force at 0.5 MPa, fitting neatly into tight transfer station footprints.
Vertical Material Lift
Raises 120 kg component racks through a 950 mm vertical stroke, requiring an external pilot-operated check valve to secure the load safely against gravity.
Injection Mold Ejection
Actuates a large mold ejection plate over a long 950 mm travel, relying on the 28 mm adjustable air cushions to decelerate the heavy 80 mm piston smoothly.
Is the Airtac SAU Standard Air Cylinder SAU80X950S the Right Cylinder?
When sizing this 80 mm bore, compare it to adjacent options: a 63 mm bore yields 1559 N push at 0.5 MPa, while a 100 mm bore provides 3927 N. This SAU80X950S fits perfectly in the heavy-duty middle ground. It shares mounting accessories with the AirTAC SC series, including LB foot, FA/FB flange, and CA/CB clevis brackets.
Because this unit features a 950 mm stroke, you must use external guide rails to support the load and prevent rod bending. Note that the adjustable air cushion only decelerates the piston near the end of travel; it will not hold a load if air pressure drops. For vertical applications, install an external rod lock or a pilot-operated check valve to prevent drifting.
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 SAU80X950S FAQ
This 80 mm bore cylinder features a 3/8 inch port and a 25 mm piston rod. It delivers 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, 4523 N push at 0.9 MPa, and a theoretical maximum of 513 kgf at 1.0 MPa.
It is not dimensionally interchangeable with ISO 15552 brackets; you must use AirTAC SC-series accessories like LB, FA, or CA mounts. However, because this SKU includes the -S magnet, you can directly mount CMSG, DMSG, or EMSG sensors into the extruded profile groove.
