About the Airtac SAID63 Double Rod Cylinder SAID63X85S
The AirTAC SAID63X85-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 63mm bore and an 85mm stroke. Because the twin rods occupy both sides of the piston, the annulus area is identical in extend and retract directions. This cylinder outputs 1402 N of force both ways at 0.5 MPa, ensuring perfectly symmetric speed and thrust. It includes a magnet for position sensing.
Equipped with a standard carbon steel rod and PT tapered ports, this through-rod design allows you to mount a workpiece on one end and a cam or position flag on the opposite rear rod end. The extruded aluminum barrel features sensor grooves on both sides, and the integrated -S magnet works seamlessly with AirTAC CMSE reed and DMSE electronic solid-state switches.

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 SAID63X85S Is Used
Symmetric Force Transfer
Ideal for automated assembly stations requiring identical push and pull thrust, utilizing the equal annulus area to move parts smoothly in both directions without speed variations.
Through-Rod Sensing
The rear rod end drives an external cam or flag, triggering a remote sensor to confirm stroke completion while the front rod handles the primary workpiece actuation.
Anti-Rotation Slides
Twin rods provide superior guidance and resist torsional twisting, making it perfect for lifting heavy parallel frames or guiding precision tooling without rotational drift.
Is the Airtac SAID63 Double Rod Cylinder SAID63X85S the Right Cylinder?
Choose this 63mm bore double-rod cylinder when an application demands equal push and pull forces—1402 N each way at 0.5 MPa—along with superior anti-rotation guidance. If your mechanism requires less force, step down to the 50mm bore (825 N both ways); if you need more thrust, the 80mm bore offers 2268 N symmetrically. The SAID is dimensionally interchangeable per ISO 15552, making it a direct replacement for other ISO 15552 double-rod cylinders.
Remember that a plain double-rod cylinder does not hold its position or load when air pressure is lost or the valve is centered; the piston will drift. If your setup must retain a load without live pressure, consider the SAIL (pneumatic lock) or BSAID (clamp-lock) variants. For this 85mm stroke, side-load stress on the rod bearing is minimal, but always ensure the rear rod has adequate physical clearance to protrude safely.
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 SAID63X85S FAQ
Because the double-rod design creates equal annulus areas on both sides of the piston, the force is identical in both directions. It delivers 1402 N at 0.5 MPa, 1962 N at 0.7 MPa, and 2523 N at 0.9 MPa for both extend and retract strokes.
Yes, it is dimensionally interchangeable per ISO 15552. However, the SAID series uses a specific mounting subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2. It omits the FB, CA, CB, and CR mounts found on single-rod cylinders to accommodate the through-rod design.
