About the Airtac SAI63 Standard Cylinder SAI63AX165S
The AirTAC SAI63X165-S is a double-acting ISO 15552 profile cylinder with a 63mm bore and a 165mm stroke. It delivers a push force of 1559 N at 0.5 MPa, making it well-suited for medium-duty handling tasks. This specific stroke length is a non-standard, made-to-order dimension tailored for specialized machine spacing requirements.
This variant includes a magnet for position sensing using CMSE or DMSE switches mounted into the dual sensor grooves on the extruded aluminum barrel. It is built with an SUS420J2 stainless steel piston rod for enhanced corrosion resistance and features PT tapered port threads.

Where the Airtac SAI63 Standard Cylinder SAI63AX165S Is Used
Custom Packaging Equipment
Fits specialized packaging machines where a precise 165mm extension is required to clear a specific folding mechanism.
Mid-Stroke Diverter
Actuates a routing gate at a non-standard distance to sort products into unique secondary processing lanes.
Automated Clamping Station
Provides 1559 N of clamping force at 0.5 MPa to hold medium-sized aluminum extrusions during machining.
Is the Airtac SAI63 Standard Cylinder SAI63AX165S the Right Cylinder?
Choose this 63mm bore when a 50mm bore falls short of the required 982 N push force at 0.5 MPa, but an 80mm bore providing 2513 N would be excessive. The 165mm stroke is a custom specification; ensure your machine layout specifically accommodates this non-standard extended length rather than defaulting to standard 150mm or 175mm options.
Because this is a standard double-acting cylinder, it relies on live air pressure to hold position. If your application drops pressure or centers the valve, the piston will drift. For vertical loads that require fail-safe holding, specify the SAIL variant with an air-released lock or use an external rod lock. As a true ISO 15552 profile cylinder, it serves as a drop-in replacement for any cylinder matching that standard's 63mm interface, utilizing G3/8 ports and standard mounting accessories like FA flanges or TC trunnions.
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 SAI63AX165S FAQ
At a 0.5 MPa operating pressure, this 63mm bore cylinder provides a push force of 1559 N and a pull force of 1402 N. At 0.7 MPa, the push force increases to 2182 N.
Yes. The SAI series is dimensionally interchangeable per ISO 15552. You can drop this into existing mounts matching the 63mm standard, provided your system uses the G3/8 port and accepts PT threaded fittings.
