Airtac SAU Standard Air Cylinder SAU100X30
The AirTAC Airtac SAU Standard Air Cylinder SAU100X30 is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 30mm stroke, 1/2" 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 SAU100X30
The AirTAC SAU100X30 is a double-acting profile-type cylinder with a 100 mm bore and 30 mm stroke. Its extruded aluminium barrel makes it shorter and more compact than an ISO 15552 cylinder of the same bore, saving valuable machine space. It delivers a robust 3927 N push and 3681 N pull at 0.5 MPa, operating through a 1/2 inch port with a 25 mm rod and M20x1.5 thread.
For practical sizing, plan for a safe working load of about 2356 N, which accounts for seal friction at 0.5 MPa. In vertical lifting applications, this translates to lifting about 200 kg with a 2:1 safety margin. The standard TPU seals handle -20 to +70 C, while a Viton H option extends this to 150 C. Note that this SKU lacks the -S magnet, so it cannot accept CMSG, DMSG, or EMSG magnetic switches.

Where the Airtac SAU Standard Air Cylinder SAU100X30 Is Used
Heavy Stamping Press
Provides 3927 N of clamping force at 0.5 MPa to hold thick metal sheets in place during a short 30 mm stamping cycle.
Injection Moulding Ejector
Delivers a rapid 30 mm ejection stroke to push heavy finished plastic parts out of a mould cavity using a 1/2 inch air port.
Pallet Stopper Gate
Acts as a high-force physical stop barrier on a conveyor line, halting loaded pallets weighing up to 200 kg vertically.
Is the Airtac SAU Standard Air Cylinder SAU100X30 the Right Cylinder?
When sizing this 100 mm bore unit, consider the neighbouring bores: a 63 mm cylinder yields 1559 N push at 0.5 MPa, while an 80 mm provides 2513 N. If 3927 N is insufficient, a larger custom solution is required as 100 mm is the largest standard SAU bore. Mount this cylinder using AirTAC SC-series accessories like LB foot, FA/FB flange, or CA/CB clevis brackets. Since this specific SKU has no -S suffix, it cannot support magnetic position sensing.
Because the SAU100X30 uses a short 30 mm stroke, side-load risks are minimal compared to longer movements. However, remember that a standard cylinder does not hold its position if air pressure drops or the valve is centered; the piston will drift. The adjustable 29 mm air cushions only decelerate the piston near the stroke ends and do not function as a braking mechanism. To secure a load safely, install an external rod lock or a pilot-operated check valve.
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 SAU100X30 FAQ
The SAU100X30 has a 1/2 inch port and delivers a push force of 3927 N and a pull force of 3681 N at 0.5 MPa. At 0.7 MPa the push force is 5497 N, and at 0.9 MPa it is 7068 N. The theoretical maximum force is 801 kgf at 1.0 MPa.
It is not an ISO 15552 cylinder, but it shares mounting dimensions with the AirTAC SC series, so use LB, FA, FB, CA, or CB accessories. Additionally, this specific SKU lacks a magnet, so it cannot accept CMSG, DMSG, or EMSG magnetic switches.
