Airtac SAU Standard Air Cylinder SAU100X65
The AirTAC Airtac SAU Standard Air Cylinder SAU100X65 is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 65mm 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 SAU100X65
The AirTAC SAU100X65 is a double-acting profile-type cylinder engineered to be physically shorter than an ISO 15552 unit of the same bore, saving valuable machine space. It handles heavy-duty tasks with a push force of 3927 N and a pull force of 3681 N at 0.5 MPa. The extruded aluminum barrel incorporates a 1/2" port, an M20x1.5 rod thread, and a 29 mm adjustable air cushion at both ends to smooth out stroke transitions.
For practical sizing, plan for a safe working load of about 2356 N, which accounts for seal friction at 0.5 MPa. This translates to lifting roughly 200 kg vertically with a 2:1 safety margin. Because this specific SKU lacks the -S magnet, it cannot host CMSG, DMSG, or EMSG sensors. If your environment exceeds the standard -20 to +70 C range, you can specify the Viton H high-temperature seal option to handle up to 150 C.

Where the Airtac SAU Standard Air Cylinder SAU100X65 Is Used
Injection Mold Clamping
Provides robust 3927 N push force at 0.5 MPa to secure heavy injection mold halves, utilizing the compact profile to fit within tight press frameworks.
Pallet Stopper Gate
Acts as a heavy-duty stopping barrier on high-mass conveyor lines, safely halting loaded pallets up to 200 kg using the 2:1 vertical lift margin.
Stamping Press Feed
Drives thick gauge material into a stamping press, relying on the 29 mm adjustable air cushions to absorb kinetic energy and prevent end-of-stroke impact.
Is the Airtac SAU Standard Air Cylinder SAU100X65 the Right Cylinder?
When sizing this 100 mm bore, you can step down to the 63 mm option for a lighter 1559 N push at 0.5 MPa, though the 100 mm is the largest standard SAU bore available. This model shares its mounting footprint with AirTAC SC-series accessories, allowing you to use LB foot brackets, FA/FB flanges, or CA/CB clevises. For this 65 mm stroke, side-load concerns are minimal, but always ensure rigid rod alignment.
Remember that a standard double-acting cylinder will drift if air pressure drops or the valve is centered; the air cushions only decelerate the piston near the end of the stroke and do not act as a braking mechanism. To suspend a load safely during an emergency stop, integrate an external rod lock or a pilot-operated check valve into your pneumatic circuit.
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 SAU100X65 FAQ
This 100 mm bore cylinder features a 1/2" 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 the theoretical maximum force is 801 kgf at 1.0 MPa.
It is not an ISO 15552 cylinder, but it is shorter and shares mounting dimensions with the AirTAC SC series, supporting LB, FA, FB, CA, and CB brackets. Additionally, this specific SKU lacks a magnet, so it cannot support CMSG, DMSG, or EMSG sensors.
