About the Airtac SAI63 Standard Cylinder SAI63X240
The AirTAC SAI63X240 is a double-acting ISO 15552 profile cylinder engineered to deliver 1559 N of push force at 0.5 MPa. Its 240 mm stroke provides the extended travel needed for mid-range automation tasks. The extruded aluminum barrel design omits tie rods, creating a clean exterior that simplifies mounting and sensor placement.
This configuration utilizes a standard carbon steel piston rod and PT tapered port threads. The barrel features dual-sided sensor grooves, allowing you to add CMSE or DMSE switches later. If your workflow requires holding a load during an air loss event, consider the SAIL variant for its pneumatic locking mechanism.

Where the Airtac SAI63 Standard Cylinder SAI63X240 Is Used
Clamping Fixtures
Provides the robust 1559 N push force required to secure heavy metal castings during CNC machining operations.
Product Diversion
Uses the 240 mm stroke to push packages smoothly across a conveyor belt transition without binding.
Press Ejection
Cycles rapidly to eject formed parts from a hydraulic press, utilizing adjustable air cushions to absorb end-of-stroke impact.
Is the Airtac SAI63 Standard Cylinder SAI63X240 the Right Cylinder?
Selecting this 63 mm bore over a 50 mm option upgrades your thrust from 982 N to 1559 N at 0.5 MPa, whereas stepping up to an 80 mm bore yields 2513 N. The 240 mm stroke falls below the 300 mm side-load threshold, but you should still ensure axial alignment to prevent premature rod-bearing wear.
As a dimensionally interchangeable ISO 15552 cylinder, it serves as a drop-in replacement for other standard profile cylinders. You can pair it with FA or FB flange accessories, specify a -S magnet for position sensing, and utilize the G3/8 PT ports for straightforward integration.

- ✓ 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.
