About the Airtac SAI63 Standard Cylinder SAI63BX165
The AirTAC SAI63X165 is a double-acting ISO 15552 profile cylinder engineered for medium-force automation tasks. Operating at 0.5 MPa, it delivers a push thrust of 1559 N and a pull thrust of 1402 N, making this 165 mm stroke variant well-suited for mid-length indexing and clamping operations.
Beyond the standard specifications, this configuration features a SUS304 stainless steel rod for superior corrosion resistance in humid or washdown environments. It utilizes PT tapered port threads, and because it lacks the -S magnet option, it relies on external positioning rather than integrated CMSE or DMSE reed switches.

Where the Airtac SAI63 Standard Cylinder SAI63BX165 Is Used
Mid-Stroke Clamping
Provides reliable 1559 N clamping force at 0.5 MPa for securing medium-sized machined parts during milling or drilling operations.
Product Diversion
Utilizes the 165 mm stroke to push packages or components cleanly from a main production line onto secondary packaging conveyors.
Press Assembly
Drives lightweight bearings or pins into housings on automated assembly lines, benefiting from the SUS304 rod in mildly corrosive shop environments.
Is the Airtac SAI63 Standard Cylinder SAI63BX165 the Right Cylinder?
Selecting this 63 mm bore unit makes sense when an application requires roughly 1559 N of push force at 0.5 MPa. If your project demands less energy, stepping down to a 50 mm bore yields 982 N, while upgrading to an 80 mm bore provides 2513 N. Because this is a double-acting actuator, it requires continuous air pressure to move and hold the rod; an unpowered piston will drift. For dead-end holding without live pressure, consider the SAIL locking variant.
As a true ISO 15552 profile cylinder, the SAI63X165 serves as a direct replacement for any standard cylinder matching these interface dimensions. To complete your assembly, specify PT port fittings, choose from FA flange or TC trunnion mounting accessories, and ensure your side loads are managed by external guides to prevent rod bearing wear.
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 SAI63BX165 FAQ
At a standard operating pressure of 0.5 MPa, this 63 mm bore cylinder generates 1559 N of push force and 1402 N of pull force. If pressure is increased to 0.7 MPa, the push force rises to 2182 N.
Yes, the SAI63X165 is built to the ISO 15552 standard, meaning its mounting dimensions are fully interchangeable with other ISO 15552 profile cylinders of the same bore size, allowing for seamless mechanical direct replacement.
