About the Airtac SAI63 Standard Cylinder SAI63BX350
The AirTAC SAI63X350 is a double-acting ISO 15552 profile cylinder engineered to deliver a push force of 1559 N and a pull force of 1402 N at 0.5 MPa. With a 63mm bore and 350mm stroke, it provides the standardized mounting interface required for seamless direct compatibility with other ISO 15552 actuators.
This specific configuration features a SUS304 stainless steel piston rod for superior corrosion resistance in humid or washdown environments. It utilizes PT tapered port threads (G3/8) and lacks a standard magnet, making it ideal for applications where external physical sensors are preferred over magnetic reed switches.

Where the Airtac SAI63 Standard Cylinder SAI63BX350 Is Used
Material Diversion
Provides the 1559 N push force needed to actuate heavy diverter gates on packaging lines over a 350mm travel distance.
Press Fit Assembly
The SUS304 rod offers reliable corrosion resistance for inserting bearings or pins in washdown manufacturing areas.
Gate Control
Delivers consistent double-acting performance for opening and closing medium-sized process gates in industrial facilities.
Is the Airtac SAI63 Standard Cylinder SAI63BX350 the Right Cylinder?
When configuring your setup, stepping down to a 50mm bore reduces the push force to 982 N at 0.5 MPa, while upgrading to an 80mm bore increases it to 2513 N. Because this 350mm stroke exceeds the 300mm threshold, the extended rod is susceptible to bending under side loads; utilizing an external guide rail or a guided cylinder is strongly recommended to prevent premature rod-bearing wear.
This model uses PT tapered port threads and a SUS304 rod. If your machinery loses air pressure, this standard cylinder cannot hold its load in place—consider the SAIL variant for pneumatic locking or the BSAI for clamp-locking. For direct replacements, match the 63mm bore, 350mm stroke, G3/8 port, and appropriate mounting accessories like the TC trunnion.
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.
