About the Airtac SAID50 Double Rod Cylinder SAID50X100
The AirTAC SAID50X100 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 50mm bore and 100mm stroke. Because a carbon steel rod extends from both end covers, the annulus area is identical on extend and retract. This yields perfectly balanced thrust, giving you 825 N of force both ways at 0.5 MPa.
This through-rod design lets you mount the primary workpiece on one end while attaching a position flag, cam, or secondary mechanism on the opposite rear rod. The extruded aluminum barrel includes sensor grooves on both sides for easy switch placement. For applications needing drop-in compatibility, it shares the exact ISO 15552 mounting interface of other standard double-rod cylinders.

Where the Airtac SAID50 Double Rod Cylinder SAID50X100 Is Used
Symmetric Force Transfer
Drives a dual-sided mechanism where equal push and pull thrust of 825 N at 0.5 MPa is critical for balanced machine timing.
Anti-Rotation Slides
The twin-rod architecture prevents piston rotation, guiding precision slides and tooling carriers without twisting under dynamic loads.
Through-Rod Sensing
Mounts the primary tool on the front rod while using the rear rod extension to trigger external position sensors or secondary cams.
Is the Airtac SAID50 Double Rod Cylinder SAID50X100 the Right Cylinder?
Choose the SAID50X100 when you need symmetric push and pull forces, or step down to a 40mm bore (528 N both ways at 0.5 MPa) for lighter duties. A double-rod profile cylinder is preferred over a single-rod SAI when your machine requires dual-side guidance, anti-rotation stability, or rear-rod actuation. Specify the PT tapered port thread and choose from Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounts.
Note that the adjustable air cushions only decelerate the piston near stroke end; they do not hold a load. If air pressure drops, the piston will drift. For position holding without live pressure, consider an external rod lock or the SAIL/BSAID variants. At 100mm stroke, side-load bending is minimal, but always verify rod bearing loads.
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 SAID50 Double Rod Cylinder SAID50X100 FAQ
Because the double-rod design subtracts the rod area from both sides of the piston, the force is equal in both directions. It provides 825 N at 0.5 MPa, 1154 N at 0.7 MPa, and 1484 N at 0.9 MPa.
Yes. The SAID50X100 is an extruded aluminum profile cylinder built to the ISO 15552 standard, making it dimensionally interchangeable with other ISO 15552 double-rod cylinders. It uses a G1/4 port and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts.
