Airtac SAU Standard Air Cylinder SAU100X225S
The AirTAC Airtac SAU Standard Air Cylinder SAU100X225S is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 225mm 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 SAU100X225S
The AirTAC SAU100X225S is a double-acting profile-type cylinder engineered for heavy-duty automation. It utilizes an extruded aluminum barrel with a built-in magnet, delivering a robust 3927 N push force at 0.5 MPa. Its profile design is significantly shorter than an ISO 15552 cylinder of the same bore, offering a distinct space advantage in large machinery without sacrificing power. The unit features a 1/2 inch port and a 25 mm carbon steel rod.
For practical sizing, plan for a safe working load of about 2356 N, which accounts for seal friction and smooth travel at 0.5 MPa. In vertical lifting applications, this translates to hoisting roughly 200 kg with a 2:1 safety margin. The piston magnet enables direct mounting of CMSG, DMSG, or EMSG sensors along the profile groove, while the standard TPU seals handle temperatures from -20 to +70 C. For high-heat environments up to 150 C, a Viton H seal option is available.

Where the Airtac SAU Standard Air Cylinder SAU100X225S Is Used
Heavy Stamping Presses
Drives heavy clamping fixtures in automotive stamping lines, utilizing the 3927 N push force to secure large metal blanks before the press cycles.
Pallet Dispenser Gates
Actuates robust gating mechanisms in automated palletizing cells, where the compact profile length frees up valuable floor space in dense conveyor layouts.
Vertical Lift Stations
Lifts loaded tooling trays weighing up to 200 kg in vertical lift stations, relying on the 25 mm rod and built-in magnet for precise height confirmation.
Is the Airtac SAU Standard Air Cylinder SAU100X225S the Right Cylinder?
When sizing this 100 mm bore actuator, evaluate your force margins carefully. Stepping down to an 80 mm bore reduces the 0.5 MPa push force to 2513 N, whereas this SAU100X225S provides 3927 N. If your application requires extreme thrust, note that this is the largest standard SAU bore available. Because this SKU includes the -S magnet, it is immediately ready for CMSG, DMSG, or EMSG electronic position sensing. Mounting hardware is fully compatible with AirTAC SC-series accessories, including LB foot mounts, FA flanges, and CA clevises.
Remember that the adjustable air cushions at both ends only decelerate the piston near the stroke limits; they do not function as a braking mechanism. If your system loses air pressure or the valve is centered, the rod will drift. To maintain a suspended load safely, integrate an external pilot-operated check valve or a dedicated rod lock 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 SAU100X225S FAQ
This 100 mm bore cylinder features a 1/2 inch port, a 25 mm rod, and M20x1.5 rod thread. At 0.5 MPa it delivers 3927 N push and 3681 N pull. 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, with an operating speed range of 30-800 mm/s.
It is not an ISO 15552 cylinder, but it shares mounting accessory compatibility with the AirTAC SC series, accepting LB, FA, and CA brackets. Because this model includes the -S magnet, you can mount CMSG, DMSG, or EMSG sensors directly into the extruded profile barrel groove for position detection.
