About the Airtac SAID80 Double Rod Cylinder SAID80X40
The AirTAC SAID80X40 is a double-acting, double-rod ISO 15552 profile cylinder engineered for symmetric actuation. Because a rod exits both ends, the annulus area is identical on extend and retract, yielding exactly 2268 N of force in each direction at 0.5 MPa. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting.
A defining advantage of this twin-rod architecture is dual-side guidance, which significantly improves resistance to torsional loads compared to a single-rod SAI. You can attach the primary workpiece to the front rod end while using the rear protrusion to drive a secondary mechanism or mount a position flag. This configuration uses a standard carbon steel rod and PT tapered ports.

Where the Airtac SAID80 Double Rod Cylinder SAID80X40 Is Used
Symmetric Force Transfer
Ideal for pressing or transferring loads where the 2268 N retraction force must precisely match the extension force to prevent mechanical binding.
Anti-Rotation Slides
The twin 25mm rods provide inherent torsional resistance, keeping guided slides perfectly aligned without external linear bearings.
Rear-Side Actuation
Drive a primary tool on the front rod while utilizing the rear rod end to trip a mechanical limit switch or actuate a secondary pneumatic valve.
Is the Airtac SAID80 Double Rod Cylinder SAID80X40 the Right Cylinder?
Select the SAID80X40 when an application demands equal push and pull forces alongside high anti-rotation stability. If your project requires less force, stepping down to the 63mm bore offers 1402 N both ways at 0.5 MPa; stepping up to the 100mm bore provides 3681 N. This 80mm bore features a 25mm rod and a G3/8 port.
For drop-in compatibility, this cylinder is dimensionally interchangeable with other ISO 15552 double-rod cylinders. It supports a reduced set of mounting accessories including 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; they do not hold the load. If position holding without live air pressure is required, consider an external rod lock or the BSAID clamp-lock variant. Because this model lacks the -S magnet, it cannot host CMSE or DMSE sensors without modification.
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 SAID80 Double Rod Cylinder SAID80X40 FAQ
Because it is a double-rod cylinder, the effective piston area is the same in both directions. It delivers 2268 N of force on both extend and retract at 0.5 MPa, and 3175 N at 0.7 MPa.
Yes, it is dimensionally interchangeable per ISO 15552. However, the SAID series uses a specific mounting subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2. It does not support FB, CA, CB, or CR brackets.
