Airtac SAUD Double Rod Cylinder SAUD63X185S
The AirTAC Airtac SAUD Double Rod Cylinder SAUD63X185S 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 SAUD63X185S
The AirTAC SAUD63X185S is a double-acting, double-rod profile cylinder. A rod exits both ends, meaning both faces use the rod-side area and push and pull force are equal at 1402 N each way at 0.5 MPa. The extruded aluminum profile barrel is shorter than an ISO 15552 cylinder of the same bore. This 63 mm bore unit has a 185 mm stroke, a 3/8 inch port, and adjustable air cushions at both ends.
Because the -S suffix indicates a built-in piston magnet, this model supports CMSG, DMSG, and EMSG switches. The dual-rod design provides anti-rotation guidance and allows a sensor cam or secondary tool to mount 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 margin.

Where the Airtac SAUD Double Rod Cylinder SAUD63X185S Is Used
Synchronized Transfer
Drives two pick-and-place grippers simultaneously from one piston, keeping motion perfectly synchronized without external linkages.
Dual-Side Detection
Uses the back protruding rod to trip a CMSG reed switch, providing precise end-of-stroke confirmation in tight machinery.
Anti-Rotation Pressing
Applies 1402 N of equal push and pull force for pressing bearings, resisting twist without needing an external linear guide.
Is the Airtac SAUD Double Rod Cylinder SAUD63X185S the Right Cylinder?
Choose this 63 mm bore if your application needs equal force in both directions, anti-twist stability, or back-end sensing. It delivers 1402 N each way at 0.5 MPa. If you need less force, the 50 mm bore provides 825 N; if you need more, step up to the 80 mm bore for 2268 N. Mounting is limited to Basic, FA flange, and LB foot types, matching the AirTAC SC series. A high-temperature Viton H seal option extends operation to 150 C. Since the 185 mm stroke is under 300 mm, side-load stress is minimal, but always guide external loads 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 SAUD63X185S FAQ
The force is equal both ways because the rod exits both ends. It generates 1402 N at 0.5 MPa, 1962 N at 0.7 MPa, and 2523 N at 0.9 MPa in both extend and retract directions. The air port is 3/8 inch.
No, the adjustable air cushion only decelerates the piston near the stroke ends and does not lock the position. To hold a load during air loss, you must add an external rod lock or a pilot-operated check valve.
