Airtac SAID40 Double Rod Cylinder SAID40X600S
The AirTAC Airtac SAID40 Double Rod Cylinder SAID40X600S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø40mm bore and 600mm stroke, G1/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAID40 Double Rod Cylinder SAID40X600S
The AirTAC SAID40X600-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 16mm carbon steel rod exiting both end covers. Because the piston sees a rod on both sides, the annulus area is identical in both directions, yielding an equal extend and retract force of 528N at 0.5 MPa. This symmetric output is ideal for mechanisms requiring consistent push and pull dynamics.
Equipped with a magnet (-S), this model supports AirTAC CMSE reed and DMSE electronic sensors along the dual-side barrel grooves. The rear rod end can simultaneously drive a secondary mechanism or carry a position flag, while the standard PT tapered G1/4 port ensures a tight pneumatic connection.

Where the Airtac SAID40 Double Rod Cylinder SAID40X600S Is Used
Symmetric Force Transfer
Drives a shuttle mechanism where the 528N push and pull forces must be perfectly matched, preventing drive imbalances during directional changes.
Anti-Rotation Slides
Uses the twin 16mm carbon steel rods exiting both covers to guide a heavy fixture, resisting rotational torque without external guide rails.
Rear-Rod Position Sensing
Mounts a DMSE electronic sensor on the barrel and a physical cam on the rear rod protrusion to trigger secondary downstream tooling simultaneously.
Is the Airtac SAID40 Double Rod Cylinder SAID40X600S the Right Cylinder?
Select this 40mm bore when an application demands equal 528N thrust in both directions, stepping up from a 32mm bore (345N) for higher capacity, or down from a 50mm bore (825N) for a lighter footprint. A double-rod design is preferred over a single-rod SAI when the mechanism requires twin-station actuation, anti-rotation guidance, or rear-rod position sensing. For drop-in replacements, verify the ISO 15552 mounting dimensions, the 600mm stroke, PT port, and accessory type. Note that the overall length is longer than a single-rod cylinder to accommodate the rear protrusion.
At 600mm of stroke, the unsupported piston rod is highly susceptible to bending under side loads. To prevent premature rod-bearing wear, an external guide rail should be used to support the load. Note that the adjustable air cushions only decelerate the piston near stroke end; this cylinder will drift if air pressure is lost. For position holding, consider an SAIL lock, BSAID clamp-lock, or external pilot-operated check valve.
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 SAID40X600S FAQ
Because the double-rod design subtracts the 16mm rod area from both sides of the piston, the force is equal in both directions. It provides 528N at 0.5 MPa, 739N at 0.7 MPa, and 950N at 0.9 MPa.
Yes, the SAID40X600-S is dimensionally interchangeable per ISO 15552. It uses a standard PT G1/4 port and supports the Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounting accessories, though you should verify rear-rod clearance.
