About the Airtac SAI63 Standard Cylinder SAI63AX90S
The AirTAC SAI63X90-S is a double-acting ISO 15552 profile cylinder delivering 1559 N of push force at 0.5 MPa. Its 90 mm stroke is well-suited for mid-range automation tasks requiring rapid, consistent linear motion. The extruded aluminum barrel design omits tie rods, providing a clean exterior that simplifies sensor placement.
This specific configuration includes a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance in humid environments. It is built with a -S magnet for direct compatibility with CMSE and DMSE series reed switches, utilizing the dual sensor grooves molded into both sides of the barrel. Porting utilizes PT tapered threads, and the unit features adjustable air cushions at both ends (36 mm stroke absorption) operating within a 30-800 mm/s speed range.

Where the Airtac SAI63 Standard Cylinder SAI63AX90S Is Used
Automated Clamping
Provides 1559 N of push force at 0.5 MPa to secure medium-sized metal workpieces during machining operations.
Package Diverting
Uses the 90 mm stroke to rapidly push packages onto secondary packaging lines at speeds up to 800 mm/s.
Material Forming
Applies consistent 2182 N of thrust at 0.7 MPa for light-duty pressing and bending tasks in fabrication cells.
Is the Airtac SAI63 Standard Cylinder SAI63AX90S the Right Cylinder?
This 63 mm bore provides 1559 N push and 1402 N pull at 0.5 MPa. If your application requires less force, stepping down to the 50 mm bore yields 982 N push at 0.5 MPa, while upgrading to the 80 mm bore offers 2513 N. For this 90 mm stroke, side-load stress on the rod bearing is minimal, but always ensure axial load alignment to maximize seal life.
As a standard double-acting cylinder, the SAI63X90-S relies on continuous air pressure to hold its position; it will drift if the air supply is exhausted or the valve is centered. If your fixture requires true position holding without live pressure, consider the SAIL variant with an air-released lock or the BSAI clamp-lock cylinder. To replace an existing unit, match the 63 mm bore, 90 mm stroke, G3/8 port, and choose an ISO 15552 mounting accessory like a TC trunnion or FA flange.
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 SAI63AX90S FAQ
