About the Airtac SAID63 Double Rod Cylinder SAID63X75
The AirTAC SAID63X75 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 63mm bore and 75mm stroke. Because the piston rod extends from both end covers, the effective annulus area is identical on both sides, yielding exactly 1402 N of output force in both extend and retract directions at 0.5 MPa. This symmetric force capability is ideal for applications requiring consistent push and pull dynamics.
A defining benefit of this twin-rod architecture is superior anti-rotation guidance and the ability to mount a secondary tool, cam, or position flag on the rear rod end. The extruded aluminum barrel includes sensor grooves on both sides, ready for CMSE reed or DMSE electronic switches if a magnet is specified later. It utilizes a standard carbon steel rod and PT tapered port threads for robust pneumatic connectivity.

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 SAID63X75 Is Used
Symmetric Force Transfer
Drives identical 1402 N push and pull forces for balanced pressing and ejection operations without needing to compensate for rod-area differences.
Anti-Rotation Slides
The twin-rod design resists torsional twisting on heavy vertical slides, keeping the workpiece perfectly aligned throughout the 75mm travel.
Rear-End Sensing
Mounts a cam or limit flag on the protruding rear rod to trigger external DMSE electronic sensors without interfering with the primary front-side tooling.
Is the Airtac SAID63 Double Rod Cylinder SAID63X75 the Right Cylinder?
Select the SAID63X75 when your mechanism demands equal push and pull forces (1402 N each way at 0.5 MPa) or requires dual-side actuation. If your application needs less force, stepping down to the 50mm bore provides 825 N both ways, while moving up to the 80mm bore offers 2268 N. Choose this double-rod design over a single-rod SAI when you need to drive a rear-mounted sensor flag or prevent the load from twisting during transit.
As a true ISO 15552 profile cylinder, it serves as a direct replacement for other standard double-rod cylinders with matching 63mm bore, 75mm stroke, and PT porting. It supports mounting accessories Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). Note that a plain SAID does not hold its position if air pressure is lost; for dead-load holding, consider an external pilot-operated check valve or the BSAID clamp-lock variant.
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 SAID63X75 FAQ
Because it is a double-rod cylinder, the effective piston area is the same on both sides. It provides equal push and pull forces of 1402 N at 0.5 MPa, 1962 N at 0.7 MPa, and 2523 N at 0.9 MPa.
Yes, the SAID63X75 is dimensionally interchangeable per ISO 15552. It shares standard mounting dimensions and uses the same accessory set (Basic, FA, LB, TC, FTC, TCM1, TCM2) as other profile cylinders in its class.
