About the Airtac SAID40 Double Rod Cylinder SAID40AX50
The AirTAC SAID40X50 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 40mm bore and 50mm stroke. Because the piston rod extends from both end covers, the effective annulus area is identical on both sides, yielding exactly 528N of force in both extend and retract directions at 0.5 MPa. This symmetric output is ideal for mechanisms requiring balanced push and pull dynamics.
Equipped with a SUS420J2 stainless steel rod and PT tapered port threads, this unit provides robust resistance to moisture and secure pneumatic connections. The extruded aluminum barrel includes sensor grooves on both sides, allowing you to mount CMSE reed or DMSE electronic switches on either end to track the rear rod position.

Where the Airtac SAID40 Double Rod Cylinder SAID40AX50 Is Used
Symmetric Transfer
Drives a transfer carriage with identical 528N push and pull force, ensuring consistent acceleration and deceleration of loads in both travel directions.
Anti-Rotation Slide
Uses the twin-rod geometry to guide a vertical slide, preventing piston rotation and maintaining precise tool alignment without external guides.
Rear-rod Sensing
Mounts a cam or target flag on the protruding rear rod to trigger DMSE electronic sensors, keeping the primary work area clear of obstructions.
Is the Airtac SAID40 Double Rod Cylinder SAID40AX50 the Right Cylinder?
Select this 40mm bore when an application demands equal force both ways, stepping up from a 32mm bore (345N) or down from a 50mm bore (825N) to hit the exact 528N requirement. A double-rod design is chosen over a single-rod SAI when you need dual-side guidance to prevent rotation, or when a rear rod is required to drive a secondary cam and flag assembly.
As a true ISO 15552 profile cylinder, it is dimensionally interchangeable with other ISO 15552 double-rod cylinders, utilizing a standard mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). Note that the adjustable air cushions only decelerate the piston near stroke end; if the air supply is lost, the cylinder will drift and cannot hold a load without an external pilot-operated check valve or a BSAID clamp-lock variant.
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 SAID40AX50 FAQ
The SAID40X50 provides equal force in both directions due to its double-rod design. It outputs 528N at 0.5 MPa, 739N at 0.7 MPa, and 950N at 0.9 MPa for both extending and retracting.
