About the Airtac SAID63 Double Rod Cylinder SAID63X175S
The AirTAC SAID63X175-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a built-in magnet for position sensing. Because a carbon steel rod extends from both end covers, the effective piston area is identical in both directions, yielding an equal push and pull force of 1402 N at 0.5 MPa. This through-rod geometry provides superior anti-rotation stability and allows you to mount a primary workpiece on the front thread while attaching a cam or position flag on the rear.
Equipped with adjustable air cushions at both ends (36 mm stroke absorption) and PT tapered ports sized at G3/8, it handles operating speeds of 30-800 mm/s smoothly. The extruded aluminum barrel integrates sensor grooves on both sides, allowing you to easily mount CMSE reed or DMSE electronic solid-state switches along either axis without extra brackets.

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 SAID63X175S Is Used
Symmetric Force Transfer
Drives a secondary mechanism from the rear rod end while delivering identical 1402 N thrust and pull forces on the primary side, ensuring balanced energy transfer without pressure spikes.
Anti-Rotation Slides
Utilizes the twin-rod structure to guide vertical lifting slides and prevent piston rotation, maintaining precise alignment for tooling across the 175 mm travel.
Dual-Side Sensing Stations
Mounts DMSE solid-state sensors in the dual barrel grooves to track the magnet position, enabling independent confirmation of both extend and retract end-strokes.
Is the Airtac SAID63 Double Rod Cylinder SAID63X175S the Right Cylinder?
Choose this 63 mm bore when an application demands symmetric force and twin-side actuation that a single-rod SAI cannot provide. If your mechanism requires less force, the 50 mm bore offers 825 N both ways at 0.5 MPa; if you need heavier thrust, stepping up to the 80 mm bore provides 2268 N. Remember that the adjustable air cushion only decelerates the piston near stroke end and does not lock the load—if air pressure is lost, the cylinder will drift, requiring an external pilot-operated check valve or a BSAID clamp-lock for true position holding.
As a dimensionally interchangeable ISO 15552 component, this cylinder serves as a direct replacement for other standard profile double-rod cylinders. To match this exact unit, specify the 63 mm bore, 175 mm stroke, G3/8 PT ports, a mounting accessory from the SAID subset (Basic, FA, LB, TC, FTC, TCM1, TCM2), and the -S magnet option. Note that the rear rod protrudes, so you must account for extra clearance behind the rear cover.

- ✓ 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 SAID63X175S FAQ
Because the double-rod design occupies volume on both sides of the piston, the extend and retract forces are equal. It generates 1402 N both ways at 0.5 MPa, 1962 N at 0.7 MPa, and 2523 N at 0.9 MPa.
Yes, it is a true ISO 15552 profile cylinder, making its mounting interface dimensionally interchangeable with other standard double-rod cylinders. Just ensure you use the SAID mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and allow clearance for the rear rod protrusion.
