About the Airtac SAID40 Double Rod Cylinder SAID40X600
The AirTAC SAID40X600 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 40mm bore and 600mm stroke. Because a carbon steel rod exits both end covers, the effective piston area is identical on extend and retract, yielding an equal 528N of force in both directions at 0.5 MPa. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE or DMSE switches.
This through-rod layout allows you to mount the primary workpiece on one end while attaching a cam, position flag, or secondary mechanism on the rear rod. It uses a PT G1/4 port and adjustable air cushions at both ends to decelerate the piston near stroke limits.

Where the Airtac SAID40 Double Rod Cylinder SAID40X600 Is Used
Symmetric Force Transfer
Drives a transfer carriage with identical 528N push and pull force at 0.5 MPa, ensuring consistent acceleration and deceleration without pressure imbalance.
Anti-Rotation Slides
The twin carbon steel rods prevent piston twist during the 600mm stroke, maintaining precise angular alignment for guided tooling and fixtures.
Through-Rod Sensing
Mounts a cam or target flag on the rear rod end to trigger external position sensors, keeping the primary work area clear of obstructions.
Is the Airtac SAID40 Double Rod Cylinder SAID40X600 the Right Cylinder?
Choose this 40mm bore model when an application requires 528N of symmetric force at 0.5 MPa (or 739N at 0.7 MPa) along with dual-side guidance. If your load demands less force, the 32mm bore offers 345N both ways, while stepping up to the 50mm bore provides 825N. The double-rod design is preferred over a single-rod SAI when you need superior anti-rotation resistance or rear-rod actuation.
At 600mm of stroke, the unsupported rod length increases susceptibility to bending under side loads, so utilizing an external guide is highly recommended. Note that a plain SAID cylinder does not hold its load when air pressure is removed; for fail-safe holding, consider an external rod lock or the SAIL/BSAID series. This model is dimensionally interchangeable per ISO 15552 and uses the SAID mounting set: Basic, FA, LB, TC, FTC, TCM1, TCM2.
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 SAID40X600 FAQ
Because the rod occupies both sides of the piston, the SAID40X600 generates equal force in both extend and retract directions. It provides 528N at 0.5 MPa, 739N at 0.7 MPa, and 950N at 0.9 MPa.
Yes, the SAID40X600 is dimensionally interchangeable with ISO 15552 profile cylinders. It supports a specific mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, but omits FB, CA, CB, and CR.
