About the Airtac SAID63 Double Rod Cylinder SAID63X250
The AirTAC SAID63X250 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 63mm bore and 250mm stroke. Because the piston rod extends from both end covers, the annulus area is identical on both sides, yielding perfectly symmetric thrust. This design outputs 1402N of force in both extend and retract directions at 0.5 MPa.
The twin-rod architecture allows you to mount the primary workpiece on the front rod while using the rear protrusion for a cam, position flag, or secondary mechanism. It features an extruded aluminum barrel with sensor grooves on both sides, adjustable air cushions at both ends, and a standard carbon steel rod with PT threaded ports.

| 0.5 MPa | 1402 N | 1402 N |
| 0.7 MPa | 1962 N | — |

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 SAID63X250 Is Used
Symmetric Transfer
Drives a workpiece forward and back with identical 1402N force and speed on both strokes, ensuring consistent timing in automated transfer lines.
Anti-Rotation Slides
The twin-rod design naturally resists torsional twisting, providing stable guidance for lifting and pressing slides without external guides.
Dual-Station Actuation
Mount a primary tool on the front rod and a secondary cam or limit flag on the rear rod to trigger sensors or drive a secondary mechanism simultaneously.
Is the Airtac SAID63 Double Rod Cylinder SAID63X250 the Right Cylinder?
Select this 63mm bore when your application requires equal push and pull forces, specifically 1402N at 0.5 MPa, alongside superior anti-rotation resistance compared to a single-rod SAI. If your project demands less force, the 50mm bore offers 825N; for heavier loads, the 80mm bore provides 2268N. At a 250mm stroke, the extended length is notably longer than a single-rod variant, so ensure you have adequate rear clearance for the through-rod.
Because this is a 250mm stroke, the 20mm rod and M16x1.25 thread experience increased bending moments under lateral loads; always use an external guide rail to support the workpiece. This cylinder uses a reduced mounting accessory set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR options. It is dimensionally interchangeable per ISO 15552. Note that standard adjustable air cushions only decelerate the piston near stroke end; they do not hold a load if air pressure is lost. For position holding, consider an external pilot-operated check valve or a BSAID clamp-lock cylinder.
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 SAID63X250 FAQ
Because it is a double-rod cylinder, the force is identical in both directions. It delivers 1402N at 0.5 MPa, 1962N at 0.7 MPa, and 2523N at 0.9 MPa for both extend and retract strokes.
Yes, the SAID63X250 is dimensionally interchangeable with other ISO 15552 profile cylinders. It uses standard mounting dimensions and a G3/8 port, making it a direct replacement for equivalent double-rod ISO cylinders.
