About the Airtac SAID40 Double Rod Cylinder SAID40AX600S
The AirTAC SAID40X600-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 40mm bore and 600mm stroke. Because a stainless SUS420J2 rod exits both end covers, the annulus area is identical on each side. This means you get exactly 528N of force at 0.5 MPa (739N at 0.7 MPa) in both extend and retract directions, ensuring perfectly symmetric speed and thrust.
Equipped with a magnet for position sensing, this variant works seamlessly with AirTAC CMSE reed and DMSE solid-state switches mounted into the dual-side sensor grooves. The through-rod design allows mounting a workpiece on the front while attaching a cam, limit flag, or secondary mechanism to the rear rod, providing superior anti-rotation guidance for your payload.

Where the Airtac SAID40 Double Rod Cylinder SAID40AX600S Is Used
Symmetric Transfer
Drives a transfer shuttle where the equal 528N both-way thrust ensures identical dynamic response whether pushing or pulling a 600mm stroke payload.
Anti-Rotation Slide
The twin-rod architecture prevents piston rotation during long 600mm traverses, keeping mounted tooling perfectly aligned without external stopper tubes.
Dual-Side Actuation
Mounts the primary workpiece on the front rod end and a secondary cam or position flag on the rear protruding rod to trigger DMSE sensors remotely.
Is the Airtac SAID40 Double Rod Cylinder SAID40AX600S the Right Cylinder?
Choose this 40mm bore when an application demands equal push and pull forces alongside dual-side actuation. If your payload requires less force, stepping down to a 32mm bore yields 345N both ways; if you need more power, a 50mm bore provides 825N both ways. The SAID series utilizes a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), deliberately omitting the FB, CA, CB, and CR brackets found on single-rod SAI cylinders.
At a 600mm stroke, the unsupported rod length is substantial. Even with a robust 16mm rod and M12x1.25 thread, long-stroke bending moments and side-load stress on the rod bearing are high. You must use an external guide rail to prevent premature seal wear. Note that the adjustable air cushions at both ends (30mm cushion length) only decelerate the piston near stroke end; they do not hold a load. If pressure is lost, the cylinder drifts—use a SAIL or BSAID lock cylinder for position holding.
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 SAID40 Double Rod Cylinder SAID40AX600S FAQ
Because the double-rod design subtracts the 16mm rod area from both sides of the piston, the force is identical in both directions. It delivers 528N at 0.5 MPa, 739N at 0.7 MPa, and 950N at 0.9 MPa for both extend and retract strokes.
Yes, the SAID40X600-S is dimensionally interchangeable per ISO 15552 profile standards, acting as a drop-in replacement for other ISO 15552 double-rod cylinders. It features a PT tapered port thread and a 30-800 mm/s speed range.
