Airtac SAU Standard Air Cylinder SAU32X25
The AirTAC SAU Standard Air Cylinder SAU32X25 is a genuine double-acting profile-type standard air cylinder with a Ø32mm bore and 25mm stroke, 1/8" 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 SAU32X25
The AirTAC SAU32X25 is a double-acting profile-type cylinder engineered for tight machinery spaces. Its extruded aluminum barrel makes it shorter than an ISO 15552 cylinder of the same 32mm bore, while sharing AirTAC SC-series mounting accessories. Operating at 0.15-1.0 MPa, it pushes 402 N and pulls 345 N at 0.5 MPa, utilizing a 1/8" port and an M10x1.25 rod thread.
This SKU lacks a magnet, so it cannot accept CMSG/DMSG/EMSG sensors. If your environment exceeds 70 C, specify the Viton H high-temperature seal option for up to 150 C operation.

Where the Airtac SAU Standard Air Cylinder SAU32X25 Is Used
Gripper Actuation
Drives small pneumatic grippers in electronics assembly, using the 25mm stroke to pick and place lightweight circuit boards.
Part Ejection
Ejects small molded plastic parts from a tooling die, leveraging the 402 N push force at 0.5 MPa to clear the mold cavity.
Flap Folding
Folds carton flaps in compact packaging lines where the short profile cylinder length prevents interference with conveyor guides.
Is the Airtac SAU Standard Air Cylinder SAU32X25 the Right Cylinder?
This 32mm bore sits at the smallest end of the SAU range; if you need more force, stepping up to the 40mm bore yields 628 N push at 0.5 MPa. Because this is a non-magnet SKU, position sensing is unavailable. Mount it using SC-series LB foot brackets, FA/FB flanges, or CA/CB clevises. Remember that standard air cushions only decelerate the piston near the end of travel; they do not hold a load. If air pressure drops, the piston will drift, so fit an external rod lock or pilot-operated check valve for vertical loads.
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 SAU32X25 FAQ
The SAU32X25 uses a 1/8" port. It generates a push force of 402 N and a pull force of 345 N at 0.5 MPa. At 0.7 MPa the push force is 563 N, and at 0.9 MPa it is 724 N. The theoretical maximum force is 82 kgf at 1.0 MPa.
No, the SAU is a compact profile cylinder, not an ISO 15552 unit. It is dimensionally shorter and must use AirTAC SC-series mounting accessories like LB foot, FA/FB flange, or CA/CB clevis brackets. Additionally, this specific SKU lacks a magnet, so magnetic position sensors cannot be fitted.
