Airtac SAU Standard Air Cylinder SAU80X950
The AirTAC Airtac SAU Standard Air Cylinder SAU80X950 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 SAU80X950
The AirTAC SAU80X950 is a double-acting profile-type cylinder featuring an extruded aluminum barrel with integrated sensor grooves. Because its envelope is shorter than an ISO 15552 cylinder of the same bore, it delivers high force in tight machine layouts without requiring external tie-rods. It pushes with 2513 N and pulls with 2268 N at 0.5 MPa, utilizing a 3/8" port and an M20x1.5 rod thread.
For practical sizing, plan for a safe working load of roughly 1508 N at 0.5 MPa to account for seal friction, which translates to lifting about 128 kg vertically with a 2:1 safety margin. The 950 mm stroke on this 80 mm bore unit exceeds standard mid-range lengths, so external guides are recommended to prevent rod bending under side loads. This SKU lacks the -S magnet, meaning it cannot accept CMSG, DMSG, or EMSG magnetic switches.

Where the Airtac SAU Standard Air Cylinder SAU80X950 Is Used
Pallet Transfer Diversion
Pushes heavy loaded pallets laterally across a high-speed packaging conveyor using its 2513 N push force at 0.5 MPa over a 950 mm span.
Vertical Lift Gate
Raises a 120 kg mezzanine safety gate, relying on the 128 kg safe vertical lift capacity while keeping the machine footprint compact.
Textile Bale Compression
Drives a long-stroke compaction ram to flatten synthetic textile bales, utilizing the 28 mm adjustable air cushions to soften end-of-stroke impact.
Is the Airtac SAU Standard Air Cylinder SAU80X950 the Right Cylinder?
When sizing this 80 mm bore actuator, compare it against adjacent bores: a 63 mm unit provides 1559 N push at 0.5 MPa, while a 100 mm unit yields 3927 N. If your application requires position feedback, select an SAU80X950-S variant instead, as this base model cannot host reed or solid-state sensors. You can mount it using AirTAC SC-series accessories like LB foot brackets, FA/FB flanges, or CA/CB clevises.
Because the 950 mm stroke creates a long lever arm, always use an external guide rail to absorb lateral forces and prevent rod deformation. Furthermore, the adjustable 28 mm air cushions only decelerate the piston near the stroke ends; they do not function as a brake. If the load must remain suspended vertically during a loss of air pressure, install an external rod lock or a pilot-operated check valve to stop drift.
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 SAU80X950 FAQ
This 80 mm bore cylinder features a 3/8" port and generates 2513 N push / 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.
No, it is not dimensionally interchangeable with ISO 15552 brackets; use AirTAC SC-series mounting accessories like LB, FA, or CA joints. Additionally, this specific SKU lacks a magnet, so you cannot mount CMSG or DMSG sensors without choosing the -S version.
