About the Airtac SAI63 Standard Cylinder SAI63AX150S
The AirTAC SAI63X150-S is a double-acting ISO 15552 profile cylinder engineered to deliver 1559 N of push force at 0.5 MPa, scaling up to 2182 N at 0.7 MPa. Its 150 mm stroke is well-suited for mid-length actuation tasks in automated machinery. By utilizing an extruded aluminum barrel design rather than traditional tie-rods, it provides a smooth, compact exterior that is dimensionally interchangeable per ISO 15552 standards.
This specific configuration includes a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance in humid environments. It is equipped with a magnet for position sensing, allowing seamless integration with CMSE or DMSE reed switches fitted into the dual sensor grooves on the barrel. Fluid supply is routed through PT (tapered) G3/8 ports, ensuring a robust, leak-free connection.

Where the Airtac SAI63 Standard Cylinder SAI63AX150S Is Used
Automated Clamping
Provides 1559 N of clamping force at 0.5 MPa for securing heavy metal components during CNC machining or welding operations.
Material Diverters
Drives 150 mm stroke diverter arms on packaging lines to route boxes into specific lanes based on sensor feedback.
Press Assembly
Powers light-duty pneumatic presses for inserting bearings or pins into housings on high-volume assembly lines.
Is the Airtac SAI63 Standard Cylinder SAI63AX150S the Right Cylinder?
When sizing this actuator, stepping down to a 50 mm bore reduces the 0.5 MPa push force to 982 N, while stepping up to an 80 mm bore increases it to 2513 N. The 150 mm stroke falls within the standard range, so no made-to-order surcharge applies. Because the stroke is under 300 mm, side-load stress on the rod bearing is minimal, though external guides are still recommended for heavy offset loads.
This cylinder is a drop-in replacement for other ISO 15552 profile cylinders without relying on proprietary brand footprints. It features a G3/8 PT port, an adjustable air cushion at both ends (36 mm stroke cushioning), and accepts standard FA/FB flanges or TC trunnion mounts. Remember that the standard SAI does not hold loads safely upon air pressure loss; for fail-safe holding, specify the SAIL (air-released lock) or BSAI (clamp-lock) variant.
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 SAI63 Standard Cylinder SAI63AX150S FAQ
At a standard 0.5 MPa operating pressure, the SAI63X150-S generates 1559 N of push force and 1402 N of pull force. At 0.7 MPa, the push force increases to 2182 N.
Yes, the -S suffix indicates this model includes a magnet. You can mount CMSE or DMSE series switches directly into the dual sensor grooves on the extruded aluminum barrel for position detection.
