About the Airtac SAI63 Standard Cylinder SAI63BX90
The AirTAC SAI63X90 is a double-acting ISO 15552 profile cylinder offering a push force of 1559 N at 0.5 MPa. Its 90 mm stroke provides a compact extension length ideal for intermediate clamping and indexing tasks. The extruded aluminum barrel design omits external tie rods, yielding a clean exterior that resists contamination.
Configured here with a SUS304 stainless steel piston rod, this variant excels in environments where moisture or corrosive elements would degrade standard carbon steel. The PT tapered port threads ensure a tight, reliable pneumatic connection, while the barrel's dual sensor grooves remain ready for future CMSE or DMSE switch integration if sensing is later required.

Where the Airtac SAI63 Standard Cylinder SAI63BX90 Is Used
Automated Clamping
Delivers 1559 N of thrust at 0.5 MPa to securely hold medium-weight metal workpieces during machining or welding operations.
Package Diverting
Uses the 90 mm stroke to actuate routing gates and pusher arms on packaging lines, accurately sorting items at up to 800 mm/s.
Material Ejection
Provides rapid, repeatable ejection of molded or stamped parts from machinery, leveraging the durable SUS304 rod for longevity.
Is the Airtac SAI63 Standard Cylinder SAI63BX90 the Right Cylinder?
Providing 1559 N of push force at 0.5 MPa, this 63 mm bore unit sits comfortably between the 50 mm (982 N) and 80 mm (2513 N) alternatives. Step down to a 50 mm bore if your payload is under 900 N to save space and air volume, or step up to an 80 mm bore if you need to overcome higher friction or move heavier masses.
Because the standard SAI lacks a physical locking mechanism, the piston will drift if air pressure is lost or the control valve centers. For vertical loads that must be held securely without live pressure, specify the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variant. This model uses a G3/8 PT port, an M16x1.5 rod thread, and accepts standard ISO 15552 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 SAI63BX90 FAQ
At a 0.5 MPa operating pressure, this 63 mm bore cylinder generates a push force of 1559 N and a pull force of 1402 N. If pressure is increased to 0.7 MPa, the push force rises to 2182 N.
Yes, the SAI63X90 is dimensionally interchangeable per ISO 15552 standards. It can serve as a direct replacement for other ISO 15552 profile cylinders, provided you match the 63 mm bore, 90 mm stroke, and G3/8 port size.
