Airtac SAUD Double Rod Cylinder SAUD63X145S
The AirTAC Airtac SAUD Double Rod Cylinder SAUD63X145S is a genuine double-acting profile-type standard air cylinder with a Ø63mm bore and 145mm 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 SAUD63X145S
The AirTAC SAUD63X145S is a double-acting, double-rod profile cylinder. A 63mm bore with a 145mm stroke yields equal push and pull thrust of 1402 N each way at 0.5 MPa. The 3/8 inch port supplies air to both chambers. Because a rod exits both ends, the effective piston area is identical in both directions.
This extruded aluminum profile body is shorter than a standard ISO 15552 unit of the same bore. The -S suffix indicates a built-in piston magnet for CMSG, DMSG, or EMSG switches. For sizing, the safe working load is roughly 841 N, and it can vertically lift about 71 kg with a 2:1 safety margin. A high-temp Viton H seal option extends operation to 150 C.

Where the Airtac SAUD Double Rod Cylinder SAUD63X145S Is Used
Synchronized Transfer
Drives two parallel pick-and-place fingers simultaneously from one piston, keeping strokes perfectly matched without twist.
Dual-End Sensing
Uses the protruding back rod to trip a CMSG or DMSG switch directly, freeing the front end entirely for tooling.
Anti-Rotation Clamping
Holds a workpiece straight via the twin rods to prevent rotational drift during high-speed machining operations.
Is the Airtac SAUD Double Rod Cylinder SAUD63X145S the Right Cylinder?
Select this 63mm bore (1402 N both ways at 0.5 MPa) if your application requires anti-rotation guidance, twin tooling, or a back-end sensor cam. Stepping up to the 80mm bore provides 2268 N, while dropping to the 50mm bore offers 825 N. Mounting is limited to Basic, FA flange, and LB foot styles, matching the AirTAC SC series. The 145mm stroke is under the 300mm threshold, so external side-load guides are less critical, but always ensure linear motion 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 SAUD63X145S 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 inch port and never quotes a larger single-rod push value.
No, the air cushions only decelerate the piston near the stroke ends; they do not act as a brake. To prevent drift on air loss, you must add an external rod lock or a pilot-operated check valve.
