Airtac SAUD Double Rod Cylinder SAUD63X300S
The AirTAC Airtac SAUD Double Rod Cylinder SAUD63X300S is a genuine double-acting profile-type standard air cylinder with a Ø63mm bore and 300mm 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 SAUD63X300S
The AirTAC SAUD63X300S is a double-acting, double-rod profile cylinder. A 20mm rod exits both ends of the hard-anodized aluminum extruded barrel, meaning both faces use the rod-side piston area. This yields identical push and pull thrust of 1402 N each way at 0.5 MPa, completely eliminating the force disparity found in single-rod units. The 3/8 inch port feeds the 63mm bore, and the integrated -S magnet enables CMSG, DMSG, or EMSG switch mounting.
Because both chambers contain a rod, you get true symmetric actuation ideal for anti-rotation guidance or driving twin tooling simultaneously. The rear protruding rod can also directly trip a external mechanical switch or carry a sensor cam. This profile body is notably shorter than an ISO 15552 cylinder of the same bore. Based on the 0.5 MPa 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 SAUD63X300S Is Used
Twin Tool Transfer
Drives two synchronized gripping fingers on a packaging line, utilizing the equal bidirectional 1402 N force to push and pull parts evenly without rotation.
Balanced Vertical Lift
Raises and lowers a 71 kg platen assembly. The dual rods provide geometric stability against twisting, while the matched thrust ensures smooth descent.
Rear Cam Sensing
Uses the back rod extension to physically trip a limit switch, while the internal magnet works with DMSG sensors for redundant position confirmation.
Is the Airtac SAUD Double Rod Cylinder SAUD63X300S the Right Cylinder?
Select this 63mm bore if your application requires equal 1402 N thrust in both directions, anti-twist stability, or rear-rod sensing. If you need less force, the 50mm bore delivers 825 N each way at 0.5 MPa. If you need more, the 80mm bore provides 2268 N. Mounting is limited to Basic, FA flange, and LB foot styles, matching the AirTAC SC series. The included -S magnet supports reed and electronic sensors. Because the stroke is 300mm, external guides are recommended to prevent rod bending under side loads. Note that a plain cylinder drifts on air loss; use a pilot-operated check valve or external rod lock for load holding.
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 SAUD63X300S FAQ
The force is equal in both directions because it is a double-rod design. 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 supplies air to the 63mm bore.
No. The adjustable air cushions only decelerate the piston near the stroke ends; they do not lock the position. If air is lost, the load will drift. You must add an external rod lock or a pilot-operated check valve for secure load holding.
