Airtac SAU Standard Air Cylinder SAU100X120S
The AirTAC Airtac SAU Standard Air Cylinder SAU100X120S is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 120mm 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 SAU100X120S
The AirTAC SAU100X120S is a double-acting profile-type cylinder engineered for heavy-duty tasks. It produces 3927 N of push force and 3681 N of pull force at 0.5 MPa. Because it uses an extruded aluminum barrel rather than a bulky standard design, this 100 mm bore unit is physically shorter than an ISO 15552 cylinder of the same size, saving valuable machine space. The 1/2" port and M20x1.5 rod thread handle high airflow and robust connections.
For practical sizing, plan for a safe working load of roughly 2356 N, which accounts for seal friction at 0.5 MPa. This translates to lifting about 200 kg vertically with a 2:1 safety margin. The included -S piston magnet allows you to mount CMSG, DMSG, or EMSG sensors directly into the barrel groove for precise end-of-stroke detection. If your environment exceeds the standard -20 to +70 C range, selecting the Viton H seal option extends operation up to 150 C.

Where the Airtac SAU Standard Air Cylinder SAU100X120S Is Used
Heavy Stamping Press
Drives a 150 kg upper die set in an automotive stamping line, utilizing the 3927 N push force to form steel panels reliably.
Pallet Dispenser
Pushes empty wooden pallets into a packaging conveyor, where the compact profile length prevents interference with tight roller clearances.
Plastic Injection Mold
Actuates a heavy mold core extraction arm, using the built-in magnet and DMSG sensor to confirm the core is fully retracted before the next cycle.
Is the Airtac SAU Standard Air Cylinder SAU100X120S the Right Cylinder?
When sizing this model, compare it against adjacent bores: a 63 mm bore yields 1559 N of push force at 0.5 MPa, while an 80 mm bore provides 2513 N. Stepping up to this 100 mm unit gives you 3927 N, making it the right choice when those smaller options lack thrust. This cylinder shares its mounting footprint with the AirTAC SC series, so you can easily reuse existing LB foot brackets, FA flanges, or CA clevises. Remember that a standard cylinder drifts if air pressure drops or the valve is centered; the adjustable 29 mm air cushions only decelerate the piston near the end of stroke and do not function as a braking lock. For suspended loads, add 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 SAU100X120S 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 it reaches a theoretical maximum of 801 kgf at 1.0 MPa.
No, it is not dimensionally interchangeable with ISO 15552 brackets, but it shares mounting accessories with the AirTAC SC series (LB, FA, CA). The -S suffix means it has a built-in magnet for CMSG, DMSG, or EMSG sensors in the profile groove.
