Airtac SAU Standard Air Cylinder SAU80X145S
The AirTAC Airtac SAU Standard Air Cylinder SAU80X145S is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 145mm 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 SAU80X145S
The AirTAC SAU80X145S is a double-acting profile-type cylinder engineered to be shorter than an ISO 15552 cylinder of the same bore, delivering a space-saving footprint for tight machinery. It operates at 0.15-1.0 MPa and generates 2513 N of push force and 2268 N of pull force at 0.5 MPa. The extruded aluminum barrel features a 3/8" port, a Ø25 mm hard-chrome rod, and an M20x1.5 rod-end thread.
Because this SKU includes the -S magnet, it readily accepts CMSG, DMSG, or EMSG switches in the profile groove for position sensing. For real-world 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 standard TPU seals handle -20 to +70 C, while a Viton H option extends heat resistance up to 150 C.

Where the Airtac SAU Standard Air Cylinder SAU80X145S Is Used
Injection Mold Clamping
Drives mid-sized mold halves or ejector pins in plastics machinery where the shorter profile length frees up valuable machine envelope without sacrificing 2513 N of clamping push.
Package Diverting Arm
Actuates a heavy routing gate on a logistics conveyor, using the built-in -S magnet and DMSG sensors to confirm gate position for high-speed sorting.
Pallet Lift Gate
Raises and lowers an 80 kg pallet stopper plate, safely operating within the 128 kg vertical lift capacity to regulate workflow at loading docks.
Is the Airtac SAU Standard Air Cylinder SAU80X145S the Right Cylinder?
When sizing this 80 mm bore, stepping down to a 63 mm bore yields 1559 N of push at 0.5 MPa, whereas stepping up to a 100 mm bore provides 3927 N. The 145 mm stroke keeps the assembly compact, but if your application approaches the 1508 N safe working load, ensure the load is guided externally to prevent rod bending. You can mount this unit using AirTAC SC-series accessories, such as LB foot brackets, FA/FB flanges, or CA/CB clevises.
Remember that the adjustable 28 mm air cushions at both ends only decelerate the piston near the stroke limits; they do not function as a brake. If the machine loses air pressure or the valve is centered, the piston will drift, so you must integrate an external rod lock or a pilot-operated check valve to sustain a suspended load safely.
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 SAU80X145S FAQ
This 80 mm bore cylinder features a 3/8" air port and generates 2513 N of push force and 2268 N of pull force at 0.5 MPa. At 0.7 MPa the push force is 3518 N, and it reaches a theoretical maximum of 513 kgf at 1.0 MPa.
No, it is not dimensionally interchangeable with ISO 15552 hardware; you must use AirTAC SC-series mounting accessories like FA flanges or LB foot brackets. However, because this model includes the -S magnet, you can directly mount CMSG, DMSG, or EMSG sensors into the barrel groove.
