About the Airtac SAID63 Double Rod Cylinder SAID63X270
The AirTAC SAID63X270 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 63mm bore and 270mm stroke. Because a carbon steel rod exits both end covers, the annulus area is identical on extend and retract, yielding equal force and speed in both directions at 1402 N each way under 0.5 MPa. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE solid-state switches.
This through-rod design allows you to mount the primary workpiece on one end and a secondary cam, position flag, or guidance mechanism on the rear rod, providing superior anti-rotation resistance. It uses a G3/8 port and adjustable air cushions at both ends to decelerate the piston near stroke limits.

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 SAID63X270 Is Used
Symmetric Force Transfer
Drives shuttle mechanisms where the 1402 N output must remain perfectly balanced in both directions without speed variations.
Anti-Rotation Slides
Twin rods prevent the piston from twisting under offset loads, ensuring precise linear guidance for machining fixtures.
Rear-Rod Sensing
Uses the protruding rear rod end to safely mount a physical position flag or cam, keeping sensors away from the main workspace.
Is the Airtac SAID63 Double Rod Cylinder SAID63X270 the Right Cylinder?
Choose this 63mm bore when an application requires symmetric push and pull forces of 1402 N at 0.5 MPa, stepping up from the 50mm bore (825 N) or down from the 80mm bore (2268 N). A double-rod cylinder is preferred over a single-rod SAI when the mechanism demands dual-side guidance, anti-rotation stability, or rear-rod actuation. Note that the SAID mounting set is limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR brackets used on single-rod variants.
With a 270mm stroke, the unsupported rod length increases; for optimal side-load resistance and to prevent rod-bearing bending, incorporate an external guide. As a dimensionally interchangeable ISO 15552 component, it serves as a direct replacement for other standard profile cylinders. Remember that standard adjustable cushions only decelerate the piston and do not hold a load; if position holding is required without live air pressure, consider a SAIL or BSAID model.
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 SAID63X270 FAQ
Because it is a double-rod cylinder, the effective piston area is the same on both sides. It delivers an equal force of 1402 N in both extend and retract directions at 0.5 MPa, and 1962 N at 0.7 MPa.
Yes. The SAID63X270 is a true ISO 15552 profile cylinder, making its mounting interface dimensionally interchangeable with other standard ISO 15552 double-rod cylinders. It uses a G3/8 port and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts.
