About the Airtac SAID63 Double Rod Cylinder SAID63BX170S
The AirTAC SAID63X170-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 63mm bore and 170mm stroke. Because a stainless steel rod exits both end covers, the annulus area is identical on each side, yielding exactly 1402 N of force in both extend and retract directions at 0.5 MPa. The integrated magnet enables position sensing.
Equipped with SUS304 stainless steel rods (material code B) and PT threaded ports, this variant excels in corrosive or washdown environments. The rear rod extension is ideal for mounting a cam, driving a secondary mechanism, or mounting a position flag, while the twin-rod geometry provides superior anti-rotation guidance compared to a single-rod SAI cylinder.

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 SAID63BX170S Is Used
Symmetric Transfer
Drives a transfer carriage with equal 1402 N force and speed in both directions, ensuring consistent cycle times for automated material handling.
Anti-Rotation Slide
Twin SUS304 rods prevent piston rotation, providing precise linear guidance for a vertical lifting slide without external guide rails.
Rear-Rod Sensing
Utilizes the rear protruding rod to mount a physical limit flag, triggering DMSE electronic sensors in a space constrained by front tooling.
Is the Airtac SAID63 Double Rod Cylinder SAID63BX170S the Right Cylinder?
Select this 63mm bore when an application demands symmetric force and speed both ways, offering 1402 N at 0.5 MPa. If your project requires less force, the 50mm bore provides 825 N; for heavier loads, the 80mm bore offers 2268 N. The double-rod design is chosen over a single-rod SAI when a rear-rod cam, dual-side guidance, or through-rod sensing is required.
This cylinder uses a PT port thread and includes a magnet for CMSE reed and DMSE electronic sensors. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2. Note that the adjustable air cushions only decelerate the piston near stroke end; they do not hold a load. If position holding without air pressure is needed, use a SAIL lock cylinder, a BSAID clamp-lock, or an external pilot-operated check valve.
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 SAID63BX170S FAQ
Because it is a double-rod cylinder, the effective piston area is the same on both sides. It provides 1402 N of force in both the extend and retract directions at 0.5 MPa, and 1962 N at 0.7 MPa.
Yes, the SAID63X170-S is dimensionally interchangeable per ISO 15552. It shares the standard mounting interface and uses the same mounting accessories, though it omits FB, CA, CB, and CR brackets which are for single-rod variants.
