About the Airtac SAID40 Double Rod Cylinder SAID40AX180S
The AirTAC SAID40X180-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 40 mm bore and 180 mm stroke. Because a rod exits both end covers, the annular piston area is identical on extend and retract, yielding a perfectly symmetric 528 N of force in each direction at 0.5 MPa. The -S suffix indicates an integrated magnet compatible with AirTAC CMSE reed and DMSE solid-state electronic sensors mounted along the dual-side barrel grooves.
This through-rod configuration allows a primary workpiece to mount on the front while a cam, position flag, or secondary mechanism drives off the rear rod. It features SUS420J2 stainless steel rods for enhanced corrosion resistance and utilizes PT tapered port threads. As a profile cylinder, it is dimensionally interchangeable per ISO 15552 mounting interface standards.

Where the Airtac SAID40 Double Rod Cylinder SAID40AX180S Is Used
Symmetric Force Transfer
Drives a transfer carriage with identical 528 N push and pull forces at 0.5 MPa, ensuring consistent cycle timing in both directions without pressure compensation.
Anti-Rotation Guidance
Utilizes the twin-rod structure to keep a heavy vertical slide guided and prevented from twisting, eliminating the need for an external linear guide rail.
Dual-Side Tooling Actuation
Mounts the primary workpiece on the front rod end and a secondary cam or limit flag on the rear rod end to trigger external mechanical switches.
Is the Airtac SAID40 Double Rod Cylinder SAID40AX180S the Right Cylinder?
Choose this 40 mm bore double-rod cylinder when an application demands equal push and pull forces alongside dual-side guidance or rear-rod actuation. If your mechanism requires less force, the neighbouring 32 mm bore provides 345 N each way; if more force is necessary, the 50 mm bore offers 825 N. The twin-rod design inherently resists torsional rotation better than a single-rod SAI cylinder.
Remember that the adjustable air cushions at both ends only decelerate the piston near stroke end; they do not lock or hold a load. If the mechanism must maintain vertical position without live air pressure, specify an external rod lock or a BSAID clamp-lock cylinder. For replacement, match the 40 mm bore, 180 mm stroke, PT port, and mounting accessory from the SAID set: Basic, FA, LB, TC, FTC, TCM1, or TCM2 (FB, CA, CB, and CR are single-rod only).
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 SAID40AX180S FAQ
Because the double-rod design subtracts the rod area on both sides of the piston, the extend and retract forces are equal. It generates 528 N in both directions at 0.5 MPa, 739 N at 0.7 MPa, and 950 N at 0.9 MPa.
Yes. As an extruded aluminum profile cylinder, it is dimensionally interchangeable per ISO 15552 mounting interface dimensions. Ensure your setup matches the G1/4 port, M12x1.25 rod thread, and the SAID mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2).
