Airtac SAUD Double Rod Cylinder SAUD63X25S
The AirTAC Airtac SAUD Double Rod Cylinder SAUD63X25S is a genuine double-acting profile-type standard air cylinder with a Ø63mm bore and 25mm stroke, 3/8" 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 SAUD Double Rod Cylinder SAUD63X25S
The AirTAC SAUD63X25S is a double-acting profile-type cylinder with a 63mm bore and 25mm stroke. A piston rod protrudes from both ends, meaning the push and pull output is identical at 1402 N each way at 0.5 MPa. The extruded aluminum barrel makes it shorter than an ISO 15552 unit of the same size, and it uses a 3/8" port with an M16x1.5 rod thread.
This -S variant includes a built-in magnet for CMSG, DMSG, or EMSG switches. The dual-rod geometry prevents rotation and lets you mount a sensor cam on the back rod. Based on the 1402 N output, the safe working load is roughly 841 N, and it can vertically lift about 71 kg with a 2:1 safety margin.

Where the Airtac SAUD Double Rod Cylinder SAUD63X25S Is Used
Synchronized Gripper Transfer
Drives two parallel pick-and-place jaws simultaneously, ensuring perfectly aligned part handling without rotational drift.
Dual-End Switch Cam
Uses the extended back rod to trip an external limit switch or mount a CMSG sensor, confirming exact retraction in tight spaces.
Short-Stroke Pinning Press
Delivers 1402 N of equal push and pull force to insert dowel pins, relying on the rigid profile body to resist deflection.
Is the Airtac SAUD Double Rod Cylinder SAUD63X25S the Right Cylinder?
Choose this 63mm bore (1402 N both ways at 0.5 MPa) if you need anti-rotation guidance or twin tooling. Step down to the 50mm bore for 825 N, or up to the 80mm bore for 2268 N. Mounting is limited to Basic, FA, and LB styles compatible with the AirTAC SC series. The -S magnet enables position sensing. At a 25mm stroke, side loads are minimal, but for any stroke over 300mm, add external guide rails to prevent binding.
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 SAUD Double Rod Cylinder SAUD63X25S FAQ
Because it is a double-rod cylinder, the force is equal in both directions: 1402 N at 0.5 MPa, 1962 N at 0.7 MPa, and 2523 N at 0.9 MPa. It uses a 3/8" port and never quotes a larger single-rod push value.
No, a plain cylinder drifts without live air, as the adjustable 21mm cushions only decelerate near stroke end. To maintain a vertical load, install an external rod lock or a pilot-operated check valve.
