About the Airtac SAID80 Double Rod Cylinder SAID80X475S
The AirTAC SAID80X475-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 475 mm stroke and an 80 mm bore. Because the piston rod exits both end covers, the annular effective area is identical in both directions, yielding equal push and pull forces of 2268 N at 0.5 MPa. This through-rod architecture is ideal for applications requiring dual-side guidance, anti-rotation stability, or mounting a secondary mechanism and position flag on the rear rod.
Equipped with a standard magnet (-S), this model integrates seamlessly with AirTAC CMSE reed and DMSE electronic sensors via the dual sensor grooves machined into the extruded aluminum barrel. It features a robust 25 mm carbon steel rod, G3/8 PT ports, and adjustable air cushions at both ends to decelerate the piston smoothly near stroke completion.

Where the Airtac SAID80 Double Rod Cylinder SAID80X475S Is Used
Symmetric Force Transfer
Drives horizontal transfer bridges requiring identical 2268 N push and pull force, ensuring consistent cycle times without force imbalance.
Anti-Rotation Slides
Powers heavy-duty lifting slides where the twin-rod design prevents the load from twisting, maintaining precise vertical alignment.
Through-Rod Sensing
Actuates a primary tool on the front rod while the rear rod end drives a physical cam for mechanical limit switching.
Is the Airtac SAID80 Double Rod Cylinder SAID80X475S the Right Cylinder?
Select this 80 mm bore double-rod cylinder when your mechanism demands symmetric force and high anti-rotation resistance, stepping up from the 63 mm bore (which provides 1402 N both ways at 0.5 MPa) to handle heavier symmetric loads. Unlike a single-rod SAI cylinder, the SAID80X475-S allows you to mount a workpiece on one end and a cam or sensor flag on the opposite rear rod end. To replace an existing ISO 15552 unit, match the 80 mm bore, 475 mm stroke, G3/8 PT ports, and select from the SAID mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2).
At 475 mm of travel, the 25 mm carbon steel rod is subjected to increased bending moments and side loads. For optimal bearing life and to prevent premature wear, implement an external linear guide to support the load rather than relying solely on the cylinder's internal rod bearing. Note that the adjustable air cushions only decelerate the piston near stroke end; they do not hold a load. If position holding is required upon air loss, use an external rod lock or pilot-operated check valve.
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 SAID80X475S FAQ
Because it is a double-rod cylinder, the effective piston area is the same in both directions. It delivers 2268 N of force both extending and retracting at 0.5 MPa, and 3175 N both ways at 0.7 MPa.
Yes, it is dimensionally interchangeable per ISO 15552. When replacing a unit, match the 80 mm bore, 475 mm stroke, G3/8 PT ports, and ensure you use a compatible mounting accessory from the SAID set (Basic, FA, LB, TC, FTC, TCM1, TCM2).
