About the Airtac SAU Standard Air Cylinder SAU63X25
The AirTAC SAU63X25 is a double-acting profile-type cylinder with a 63 mm bore and 25 mm stroke. It uses an extruded aluminum barrel that is shorter than an ISO 15552 cylinder of the same bore, saving valuable machine space. It delivers a push force of 1559 N and a pull force of 1402 N at 0.5 MPa, with a 3/8" port and an M16x1.5 rod thread.
Because this SKU lacks the -S magnet, it cannot host CMSG, DMSG, or EMSG sensors. The standard TPU seals handle -20 to +70 C, while a Viton H option extends heat resistance to 150 C.

Where the Airtac SAU Standard Air Cylinder SAU63X25 Is Used
Short-Stroke Clamping
Applies 1559 N of push force at 0.5 MPa to secure heavy steel plates during CNC machining using a compact 25 mm stroke.
Package Diverter
Executes rapid 25 mm shifts to route heavy cartons on a packaging line, operating reliably at speeds up to 800 mm/s.
Press Ejection
Kicks finished metal parts out of a stamping press, utilizing the 1402 N pull force to retract the rod quickly.
Is the Airtac SAU Standard Air Cylinder SAU63X25 the Right Cylinder?
This 63 mm bore fits neatly between the 50 mm (982 N push at 0.5 MPa) and 80 mm (2513 N push) options, letting you scale force precisely. The 25 mm stroke is ideal for short clamping or ejection movements. Mounting relies on AirTAC SC-series accessories like LB foot, FA/FB flange, or CA/CB clevis, plus I, Y, F, or U knuckles.
Remember that a standard SAU cylinder drifts if air pressure drops or the valve centers, as the adjustable 21 mm end cushions only decelerate the piston and do not act as a brake. Use an external rod lock or pilot-operated check valve if your application requires strict load holding.
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 SAU63X25 FAQ
This 63 mm bore model features a 3/8" port and an M16x1.5 rod thread. It delivers 1559 N push and 1402 N pull at 0.5 MPa, 2182 N push at 0.7 MPa, 2805 N push at 0.9 MPa, and a theoretical maximum of 318 kgf at 1.0 MPa.
No, because this specific SKU does not include the -S magnet option, it cannot accept CMSG, DMSG, or EMSG magnetic switches. You would need the SAU63X25-S variant for sensor groove compatibility.
