Airtac SAUD Double Rod Cylinder SAUD63X185
The AirTAC Airtac SAUD Double Rod Cylinder SAUD63X185 is a genuine double-acting profile-type standard air cylinder with a Ø63mm bore and 185mm 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 SAUD63X185
The AirTAC SAUD63X185 is a double-acting, double-rod profile cylinder with a 63 mm bore and 185 mm stroke. Because a rod protrudes from both ends, the push and pull output is identical, yielding 1402 N of force each way at 0.5 MPa. The extruded aluminium barrel keeps the unit shorter than a standard ISO 15552 model of the same size, and it uses a 3/8 inch port with an M16x1.5 rod thread.
This twin-rod geometry provides inherent anti-rotation guidance and lets you mount a cam on the back rod, though this specific SKU lacks a magnet and cannot host a sensor switch. The design yields a safe working load of roughly 841 N, or a vertical lift capacity of about 71 kg with a 2:1 safety margin. Standard seals handle -20 to +70 C, while a Viton H option extends heat resistance up to 150 C.

Where the Airtac SAUD Double Rod Cylinder SAUD63X185 Is Used
Twin-Spindle Drilling
Drives two synchronized machining heads from opposite rod ends, ensuring perfectly matched feed rates without twist.
Dual-End Transfer Arm
Pushes a workpiece forward while simultaneously retracting a secondary stopper on the back side for timed pacing.
Guided Lift Gate
Raises and lowers a 71 kg vertical load using the inherent anti-rotation properties of the dual rods for smooth travel.
Is the Airtac SAUD Double Rod Cylinder SAUD63X185 the Right Cylinder?
Selecting this 63 mm bore over the smaller 50 mm (825 N) or larger 80 mm (2268 N) gives you 1402 N of equal bidirectional force at 0.5 MPa. A double-rod unit is the right call when your mechanism demands strict non-rotating anti-twist guidance or needs to drive two tools at once. Mounting is limited to Basic, FA flange, and LB foot styles, matching the AirTAC SC series. At 185 mm, side loads are minimal, but any stroke over 300 mm requires an external guide to prevent rod binding. Note that this non-magnetic SKU cannot accept CMSG or DMSG switches; choose a -S variant if you need position sensing.
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 SAUD63X185 FAQ
The force is equal in both directions due to the double-rod design. It provides 1402 N at 0.5 MPa, 1962 N at 0.7 MPa, and 2523 N at 0.9 MPa. The unit features a 3/8 inch port and operates at speeds between 30 and 800 mm/s.
No, a plain double-rod cylinder drifts without live air; the adjustable 21 mm cushions only decelerate near stroke ends. For a locked load, install an external rod lock or pilot-operated check valve. Also, this non-magnet SKU cannot mount sensors.
