About the Airtac SAID63 Double Rod Cylinder SAID63X175
The AirTAC SAID63X175 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 63mm bore and 175mm stroke. Because a carbon steel rod exits both end covers, the annulus areas are identical, yielding equal push and pull forces. It delivers 1402 N of thrust and retraction force at 0.5 MPa, ensuring perfectly symmetric motion. The barrel is extruded aluminum with sensor grooves on both sides.
This through-rod design allows you to mount the primary workpiece on one end and a position flag or cam on the rear. It provides superior anti-rotation guidance compared to a single-rod SAI. The adjustable air cushions at both ends decelerate the piston smoothly, though it will not hold a load if air pressure drops.

Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAID63 Double Rod Cylinder SAID63X175 Is Used
Symmetric Force Transfer
Delivers identical 1402 N force in both directions, ensuring perfectly balanced pushing and pulling without pressure compensation.
Anti-Rotation Slides
The twin-rod design prevents piston rotation, providing precise linear guidance for handling and clamping modules.
Rear-Side Cam Actuation
The protruding rear rod can drive a secondary mechanism or cam, enabling synchronized dual-station actuation from one cylinder.
Is the Airtac SAID63 Double Rod Cylinder SAID63X175 the Right Cylinder?
Choose this 63mm bore when an application demands perfectly balanced bidirectional force and high torsional rigidity. If you need less force, the 50mm bore offers 825 N both ways at 0.5 MPa; if you need more, the 80mm bore provides 2268 N. The SAID63X175 uses a G3/8 PT port and supports mountings Basic, FA, LB, TC, FTC, TCM1, and TCM2. It omits the FB, CA, CB, and CR brackets found on single-rod variants.
Since this is a non-magnet model, position sensing requires external flags or a separate setup. For direct replacements, it is dimensionally interchangeable per ISO 15552. While the 20mm rod handles typical side loads well, strokes of 300mm or more require external guides to prevent rod-bearing bending.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/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/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAID63 Double Rod Cylinder SAID63X175 FAQ
Because it is a double-rod cylinder, the effective area is the same on both sides. It outputs 1402 N in both extend and retract directions at 0.5 MPa, and 1962 N at 0.7 MPa.
No, the adjustable air cushions only decelerate the piston near the stroke ends. It cannot hold a vertical load without live pressure. For holding, consider the SAIL or BSAID series.
