About the Airtac SAID40 Double Rod Cylinder SAID40AX230S
The AirTAC SAID40X230-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 40mm bore and 230mm stroke. Because a rod exits both end covers, the annulus area is identical on extend and retract, yielding equal push and pull forces of 528N at 0.5 MPa and 739N at 0.7 MPa. The extruded aluminum barrel includes sensor grooves on both sides, and the -S magnet enables position detection via CMSE reed or DMSE solid-state switches.
This variant uses a SUS420J2 stainless steel rod (material code A) for superior corrosion resistance compared to standard carbon steel. The twin-rod architecture allows you to mount a workpiece on the front rod and a cam or position flag on the rear rod, providing dual-side guidance and enhanced anti-rotation stability. PT tapered port threads (G1/4) ensure a tight, reliable pneumatic connection.

Where the Airtac SAID40 Double Rod Cylinder SAID40AX230S Is Used
Symmetric Force Transfer
Drives a workpiece back and forth with exactly 528N of force in both directions at 0.5 MPa, ensuring perfectly balanced push and pull dynamics for precision handling.
Dual-Station Actuation
Utilizes the through-rod design to operate a secondary mechanism or tooling station from the rear rod end while the primary tooling mounts on the front.
Anti-Rotation Slides
Leverages the twin-rod guidance to prevent the payload from twisting during transit, maintaining strict angular alignment on linear slides.
Is the Airtac SAID40 Double Rod Cylinder SAID40AX230S the Right Cylinder?
Select this 40mm bore model when an application demands symmetric force and speed in both directions, stepping up from the 32mm bore (345N at 0.5 MPa) for higher thrust, or down from the 50mm bore (825N at 0.5 MPa) for a smaller footprint. A double-rod design is preferred over a single-rod SAI when you need to drive twin stations, attach a rear-side sensor flag, or prevent the load from twisting during transit. To match ISO 15552 interchangeability, verify the 40mm bore, 230mm stroke, PT port, and compatible mounting accessory (Basic, FA, LB, TC, FTC, TCM1, or TCM2; note SAID omits FB, CA, CB, and CR).
Because this stroke is 230mm, the extended rod can generate leverage that increases side-load bending on the rod bearing; for long unsupported loads, use an external guide rail. Note that a plain SAID does not hold its position when air pressure is lost or exhausted—the piston drifts—so for safety holding without live pressure, consider an SAIL lock, BSAID clamp-lock, or external rod lock.

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 SAID40AX230S FAQ
Because the double-rod design subtracts the rod area from both sides of the piston, the extend and retract forces are equal. This 40mm bore cylinder generates 528N at 0.5 MPa, 739N at 0.7 MPa, and 950N at 0.9 MPa in both directions.
Yes, the SAID40X230-S is dimensionally interchangeable per ISO 15552 profile standards and can serve as a drop-in replacement for other ISO 15552 double-rod cylinders. It uses PT G1/4 ports and a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2).
