Airtac SAU Standard Air Cylinder SAU100X500S
The AirTAC Airtac SAU Standard Air Cylinder SAU100X500S is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 500mm 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 SAU100X500S
The AirTAC SAU100X500S is a double-acting profile-type cylinder with a 100 mm bore and 500 mm stroke. It uses an extruded aluminum barrel that is physically shorter than an ISO 15552 cylinder of the same bore, yielding a space advantage in large-scale machinery. Operating at 0.5 MPa, it delivers a push force of 3927 N and a pull force of 3681 N, with a 1/2" port and M20x1.5 rod thread. The integrated -S piston magnet enables CMSG, DMSG, or EMSG solid-state switches to drop directly into the profile groove for position sensing.
For practical sizing, plan for a safe working load of about 2356 N, which accounts for seal friction at 0.5 MPa. In a vertical lift scenario, this equates to lifting roughly 200 kg with a 2:1 safety margin. The standard TPU seals handle temperatures from -20 to +70 C, while a Viton H option extends this range up to 150 C for high-heat environments.

Where the Airtac SAU Standard Air Cylinder SAU100X500S Is Used
Heavy Stamping Press
Drives a 150 kg lower die set into a hydraulic press, using the 3927 N push force to seat the tooling firmly.
Pallet Dispenser
Pushes empty pallets out of a vertical magazine over the 500 mm stroke, relying on the compact profile to fit tight conveyor frames.
Scissor Lift Actuation
Extends a heavy-duty scissor table for loading docks, moving payloads safely with a 2:1 vertical lift margin around 200 kg.
Is the Airtac SAU Standard Air Cylinder SAU100X500S the Right Cylinder?
When sizing this actuator, evaluate the neighboring bores: the 80 mm variant provides 2513 N push at 0.5 MPa, whereas the 100 mm unit offers 3927 N. Because this is a 500 mm stroke, external guide rails are strongly recommended to prevent rod bending and absorb side loads. This unit includes the -S magnet for sensors; without it, the groove remains empty. Mounting hardware matches the AirTAC SC series, accepting LB foot brackets, FA/FB flanges, and CA/CB clevises. Remember that the adjustable air cushion only decelerates the piston near the end of travel; it does not function as a braking device. If the load must remain suspended during air loss, 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 SAU100X500S FAQ
This 100 mm bore model features a 1/2" port. At 0.5 MPa it pushes with 3927 N and pulls with 3681 N. 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.
No, the adjustable air cushion only decelerates the piston near the end of its stroke and does not lock the rod. If air is lost, the piston will drift. You must add an external rod lock or a pilot-operated check valve to hold a vertical load safely.
