About the Airtac SAID63 Double Rod Cylinder SAID63X150
The AirTAC SAID63X150 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 63mm bore and 150mm stroke. Because a carbon steel rod exits both ends, the annulus area is identical on extend and retract, yielding exactly 1402 N of force each way at 0.5 MPa. It uses a G3/8 port and adjustable air cushions at both ends to decelerate the piston.
This through-rod design allows mounting a primary workpiece on one end and a position flag, cam, or secondary mechanism on the rear rod. The extruded aluminum barrel includes sensor grooves on both sides. You can fit CMSE reed or DMSE electronic switches if a magnet is specified, and it shares the exact mounting interface of standard ISO 15552 cylinders.

Theoretical Output Force (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1402 N | 1402 N |
| 0.7 MPa | 1962 N | — |
| Max (@1.0 MPa) | 286 kgf | |
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 SAID63X150 Is Used
Symmetric Force Transfer
Provides identical 1402 N thrust in both directions for pushing and pulling mechanisms that require perfectly balanced kinetic energy.
Anti-Rotation Slides
The twin-rod configuration prevents piston rotation, guiding heavy vertical or horizontal loads without twisting under pressure.
Rear-Rod Actuation
Drives a primary tool on the front rod while utilizing the rear rod extension to trigger external cam sensors or secondary motions.
Is the Airtac SAID63 Double Rod Cylinder SAID63X150 the Right Cylinder?
Choose this 63mm bore over a 50mm unit when you need more thrust, stepping up from 825 N to 1402 N at 0.5 MPa. Conversely, drop to a 50mm bore if your application requires less than 825 N to save space. The double-rod architecture is selected over a single-rod SAI when twin-side guidance, anti-rotation resistance, or rear-rod actuation is required. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.
Note that the adjustable cushion only decelerates the piston near stroke end; it does not hold a load. If the air supply is lost or the valve is centered, the cylinder drifts, so use a SAIL lock, BSAID clamp-lock, or external rod lock for position holding. Ensure you specify a PT tapered port thread and add the -S magnet suffix if position sensing is needed.
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 SAID63X150 FAQ
Because the double-rod design occupies piston area on both sides, the extend and retract forces are equal. It provides 1402 N of force each way at 0.5 MPa, 1962 N at 0.7 MPa, and 2523 N at 0.9 MPa.
Yes, the SAID63X150 is dimensionally interchangeable per ISO 15552 profile cylinder standards. It serves as a direct replacement for other ISO 15552 double-rod cylinders with a 63mm bore and 150mm stroke, using the same mounting interface.
