About the Airtac SAID40 Double Rod Cylinder SAID40AX260
The AirTAC SAID40X260 is a double-acting, double-rod ISO 15552 profile cylinder engineered to provide exactly 528N of force in both extend and retract directions at 0.5 MPa. Because the piston rod exits both end covers, the annulus area is identical on both sides, ensuring perfectly symmetric thrust and travel speeds.
This configuration features a SUS420J2 stainless steel rod for enhanced corrosion resistance and utilizes PT tapered port threads. The twin-rod architecture allows operators to mount a primary workpiece on the front rod while using the rear protrusion to drive a secondary mechanism or carry a position flag.

Where the Airtac SAID40 Double Rod Cylinder SAID40AX260 Is Used
Symmetric Transfer
Drives a transfer carriage with identical 528N force and speed in both directions, ensuring perfectly balanced part shuttling without momentum discrepancies.
Anti-Rotation Slide
The twin-rod layout keeps the guided load perfectly straight during the 260mm stroke, resisting torsional twist that would bind a single-rod cylinder.
Dual-Tool Actuation
Mounts a primary gripper on the front rod end and a secondary cam on the rear protrusion to trigger an external mechanical valve at mid-stroke.
Is the Airtac SAID40 Double Rod Cylinder SAID40AX260 the Right Cylinder?
Select this 40mm bore when an application requires equal push and pull forces, specifically 528N at 0.5 MPa, which is less than the 63mm bore (1402N) but more capable than the 32mm bore (345N). A double-rod design is preferred over a single-rod SAI when the load requires dual-side guidance to prevent rotation or when a rear-mounted cam is needed for external sensing.
Because this model lacks a magnet, it cannot host internal CMSE or DMSE sensors; external limit switches must be used instead. Note that the adjustable air cushion only decelerates the piston near stroke end and does not lock the load; if position holding without live air pressure is required, consider a SAIL or BSAID variant. For this 260mm stroke, ensure an external guide supports the load to prevent rod-bearing bending under side loads. It is dimensionally interchangeable per ISO 15552.
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 SAID40AX260 FAQ
Because it is a double-rod cylinder, the effective piston area is identical on both sides. It delivers 528N of force in both the extend and retract directions at 0.5 MPa, and 739N at 0.7 MPa.
Yes, the SAID40X260 is dimensionally interchangeable per ISO 15552 mounting dimensions. It uses a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.
