About the Airtac SAI63 Standard Cylinder SAI63AX175S
The AirTAC SAI63X175-S is a double-acting ISO 15552 profile cylinder engineered for precise linear motion. Delivering a push force of 1559 N at 0.5 MPa, this 63mm bore unit is built to handle mid-range industrial workloads efficiently. The 175mm stroke provides ample travel for packaging and material handling tasks.
This specific configuration includes a SUS420J2 stainless steel rod (code A) for superior corrosion resistance and mechanical durability. It also features a built-in magnet (-S) that integrates seamlessly with CMSE and DMSE series sensor switches, utilizing the dual sensor grooves machined into the extruded aluminum barrel.

Where the Airtac SAI63 Standard Cylinder SAI63AX175S Is Used
Component Clamping
Provides reliable 1559 N clamping force at 0.5 MPa for securing metal workpieces during machining operations.
Package Diverting
Utilizes the 175mm stroke to push and divert heavy packages on automated sorting conveyor lines.
Gate Control
Actuates safety gates and heavy access doors on automated factory floors with consistent power.
Is the Airtac SAI63 Standard Cylinder SAI63AX175S the Right Cylinder?
Choose this 63mm bore cylinder when a 50mm bore (offering 982 N push at 0.5 MPa) lacks the necessary thrust, but an 80mm bore (2513 N) would be excessive. The G3/8 PT tapered port ensures optimal airflow for the 30-800 mm/s speed range. For drop-in replacements, verify ISO 15552 mounting dimensions, the 175mm stroke, and compatible accessories like FA flanges or TC trunnions.
Because the stroke is below 300mm, side-load stress on the rod bearing is naturally reduced. However, if your application requires holding a load vertically without continuous air pressure, note that the standard SAI cylinder will drift. In such cases, select the SAIL variant with an air-released lock or utilize 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 SAI63 Standard Cylinder SAI63AX175S FAQ
