Airtac SAUD Double Rod Cylinder SAUD63X85
The AirTAC Airtac SAUD Double Rod Cylinder SAUD63X85 is a genuine double-acting profile-type standard air cylinder with a Ø63mm bore and 85mm 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 SAUD63X85
The AirTAC SAUD63X85 is a double-acting, double-rod profile cylinder with an 85mm stroke. A rod exits both ends, meaning both faces use the rod-side area. Output is equal in both directions at 1402 N each way at 0.5 MPa. The extruded aluminum barrel is shorter than an ISO 15552 cylinder of the same bore. It uses a 3/8 inch port and an M16x1.5 rod thread.
This unit lacks the -S magnet option, so it cannot accept CMSG or DMSG sensors. A safe working load is roughly 841 N, or a vertical lift of about 71 kg with a 2:1 margin. The standard TPU seals operate from -20 to +70 C, while a Viton H option extends this to 150 C. Mounting is limited to Basic, FA, and LB types matching the AirTAC SC series.

Where the Airtac SAUD Double Rod Cylinder SAUD63X85 Is Used
Twin-Tool Stamping
Drives two synchronized forming tools from one piston, ensuring parallel contact without rotational twist.
Dual Pusher Array
Pushes a product from one lane to another using both rod ends simultaneously for mirrored routing.
Gripping Cam Trip
Uses the rear protruding rod to mechanically trip a limit switch or release a mechanical latch.
Is the Airtac SAUD Double Rod Cylinder SAUD63X85 the Right Cylinder?
Choose this 63mm bore when you need 1402 N of force in both directions. If you need less force, the 50mm bore provides 825 N. If you need more, the 80mm bore provides 2268 N. A double rod is the right call for anti-rotation guidance, driving twin tooling, or carrying a switch cam on the back end. Mount via Basic, FA flange, or LB foot. Because this is a plain SKU without the -S magnet, you cannot mount magnetic sensors. For any stroke over 300mm, use external guide rails to prevent side-load wear.
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 SAUD63X85 FAQ
Because it is a double-rod cylinder, the force is equal in both directions. It outputs 1402 N at 0.5 MPa, 1962 N at 0.7 MPa, and 2523 N at 0.9 MPa. The 3/8 inch port feeds both chambers equally.
No. The air cushions only decelerate the piston near the stroke end; they do not lock. If air is lost, the piston drifts. Use an external rod lock or pilot-operated check valve for load holding.
