Airtac SAU Standard Air Cylinder SAU80X5
The AirTAC Airtac SAU Standard Air Cylinder SAU80X5 is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 5mm 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 SAU80X5
The AirTAC SAU80X5 is a double-acting profile-type cylinder with a 5 mm stroke and a 3/8" port. Its extruded aluminum barrel makes it shorter than an ISO 15552 cylinder of the same bore, saving valuable space in tight machinery layouts. It delivers a robust 2513 N of push force at 0.5 MPa.
Because this SKU lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG sensor switches. For real-world sizing, plan for a safe working load of roughly 1508 N, which accounts for seal friction at 0.5 MPa. If lifting vertically, this bore comfortably hoists about 128 kg with a 2:1 safety margin.

Where the Airtac SAU Standard Air Cylinder SAU80X5 Is Used
Short-Stroke Clamping
Ideal for securing heavy steel plates in fabrication fixtures, utilizing the 2513 N push force to lock parts firmly within a compact press envelope.
Ejection Mechanism
Provides a rapid 5 mm ejection punch for thick composite sheets from molding dies, taking advantage of the space-saving profile barrel.
Riveting Press
Delivers concentrated impact for riveting thick structural brackets, where the robust 80 mm bore ensures consistent pressure without yielding.
Is the Airtac SAU Standard Air Cylinder SAU80X5 the Right Cylinder?
When sizing this 80 mm bore, the 63 mm option provides 1559 N push at 0.5 MPa, while the 100 mm bore yields 3927 N at the same pressure. Choose the SAU80X5 when you need heavy thrust in a confined footprint. Since this 5 mm stroke is extremely short, side-load risks are minimal, but always ensure rigid mounting using AirTAC SC-series accessories like LB foot or FA flange brackets.
Note that this non-magnetized version cannot support position sensing. Furthermore, the adjustable air cushion only decelerates the piston near stroke end; it will not hold a load if air pressure drops. For suspended loads, integrate an external rod lock or a pilot-operated check valve to prevent 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 SAU80X5 FAQ
The SAU80X5 features a 3/8" port and generates 2513 N push and 2268 N pull at 0.5 MPa. At 0.7 MPa it pushes 3518 N, and 4523 N at 0.9 MPa. The theoretical maximum force is 513 kgf at 1.0 MPa.
No, it is not an ISO 15552 cylinder. It is a compact profile cylinder that uses AirTAC SC-series mounting accessories, such as LB foot, FA flange, or CA clevis brackets. Also, this specific SKU lacks a magnet, so magnetic sensors cannot be fitted.
