About the Airtac SAI40 Standard Air Cylinder SAI40AX600S
The AirTAC SAI40X600-S is a double-acting ISO 15552 profile cylinder engineered for applications requiring a 600mm stroke. It delivers a push force of 628N at 0.5 MPa, extending to 879N at 0.7 MPa. This makes it suitable for mid-range automation tasks needing substantial travel distance. As a genuine AirTAC component, it ensures reliable pneumatic performance.
This specific configuration includes a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance. The -S suffix indicates an integrated magnet, allowing seamless operation with CMSE or DMSE reed switches fitted into the dual sensor grooves on the extruded aluminum barrel. Fluid ports are PT threaded, matching standard global pneumatic fittings.

Where the Airtac SAI40 Standard Air Cylinder SAI40AX600S Is Used
Long-Stroke Material Handling
Pushes products or pallets across a 600mm transfer gap with 879N of force at 0.7 MPa, utilizing the long stroke to bridge distant conveyor lanes.
Vertical Lifting Gates
Raises and lowers lightweight access doors or safety gates. The SUS420J2 rod provides reliable operation even in environments with high ambient humidity.
Automated Tool Indexing
Shifts tooling carriages linearly to change machine setups. The dual sensor grooves allow flexible mounting of DMSE switches for precise end-position feedback.
Is the Airtac SAI40 Standard Air Cylinder SAI40AX600S the Right Cylinder?
Select this 40mm bore cylinder when a 32mm bore lacks the necessary travel stability or force (402N at 0.5 MPa), but a 63mm bore (1559N at 0.5 MPa) would be excessive. The 600mm stroke falls within the standard maximum range of 1200mm for this bore size, providing a long reach without requiring a custom made-to-order part.
Because the stroke is 600mm, the unsupported rod length is significant. Avoid side loading that could bend the rod or accelerate rod-bearing wear; use an external guide rail or a guided cylinder assembly for heavy off-center loads. If the mechanism must hold position without continuous air pressure, pair this cylinder with an external pilot-operated check valve or specify the SAIL locking variant, as the standard air cushion only decelerates the piston at stroke ends.
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.
