About the Airtac SAI63 Standard Cylinder SAI63BX90S
The AirTAC SAI63X90-S is a double-acting ISO 15552 profile cylinder engineered for mid-range actuation, delivering a push force of 1559 N at 0.5 MPa. Its 90 mm stroke provides compact extension for clamping, lifting, and positioning tasks within standardized machinery footprints.
This configuration features a SUS304 stainless steel rod for superior corrosion resistance and includes a built-in magnet for position sensing. The extruded aluminum barrel incorporates dual sensor grooves compatible with CMSE and DMSE switches, while fluid connections use PT tapered threads.

Where the Airtac SAI63 Standard Cylinder SAI63BX90S Is Used
Mid-Tonnage Clamping
Secures heavy workpieces during CNC machining operations where consistent 1559 N clamping force is required.
Package Diverting
Actuates routing gates on high-speed packaging lines, utilizing the 90 mm stroke to redirect products efficiently.
Material Lifters
Raises and lowers lightweight platens in automated assembly cells, benefiting from the precise position feedback of the integrated magnet.
Is the Airtac SAI63 Standard Cylinder SAI63BX90S the Right Cylinder?
Selecting this bore is ideal when a 50 mm bore (982 N at 0.5 MPa) lacks sufficient thrust but an 80 mm bore (2513 N) would be physically oversized. The 90 mm stroke keeps the retracted length short, minimizing space requirements along the machine axis.
Because this standard SAI variant lacks a locking mechanism, it cannot hold a load if air pressure is lost; use the SAIL lock variant for fail-safe holding. As a true ISO 15552 profile cylinder, it serves as a direct replacement for other ISO 15552 cylinders, matching the 63 mm bore, 90 mm stroke, G3/8 port, 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.
