About the Airtac SAID50 Double Rod Cylinder SAID50X75
The AirTAC SAID50X75 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 50mm bore and 75mm stroke. Because a carbon steel rod exits both end covers, the annulus area is identical on extend and retract, yielding equal force and speed in both directions at 825N each way (0.5 MPa). The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic switches.
This twin-rod architecture is purpose-built for applications requiring dual-side guidance and anti-rotation. You can mount the primary workpiece on one rod end and a position flag, cam, or secondary tool on the rear rod end. It uses adjustable air cushions at both ends (30mm cushion length) to decelerate the piston smoothly.

Where the Airtac SAID50 Double Rod Cylinder SAID50X75 Is Used
Symmetric Transfer
Drives a transfer shuttle where the equal 825N extend and retract forces ensure consistent motion dynamics without needing pressure compensators.
Anti-Rotation Slide
Guides a vertical lifting slide via the twin rods exiting both covers, preventing mechanical binding and torsional deflection.
Rear-Cam Actuation
Mounts the primary tool on the front rod while the rear rod end drives a secondary cam or mechanical flag for external sequencing.
Is the Airtac SAID50 Double Rod Cylinder SAID50X75 the Right Cylinder?
Select this 50mm bore when an application demands perfectly symmetric force (825N at 0.5 MPa) and inherent anti-rotation resistance that a single-rod SAI cannot provide. If your project requires less force, the 40mm neighbor offers 528N; if you need more push/pull, step up to the 63mm bore providing 1402N. The PT tapered port is G1/4.
Ensure you specify the correct mounting accessories from the SAID subset: Basic, FA, LB, TC, FTC, TCM1, or TCM2 (note that FB, CA, CB, and CR are exclusive to single-rod SAI). Remember that a plain SAID does not hold its load when air is exhausted or the valve is centered; the piston will drift. For position holding without live pressure, consider an external rod lock, SAIL, or BSAID. This cylinder is dimensionally interchangeable per ISO 15552, serving as a drop-in replacement for other ISO 15552 double-rod cylinders.
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 SAID50X75 FAQ
The SAID50X75 provides 825N of force at 0.5 MPa, 1154N at 0.7 MPa, and 1484N at 0.9 MPa. Because it is a double-rod cylinder, this force is identical in both the extend and retract directions.
Yes, the SAID50X75 is dimensionally interchangeable per ISO 15552. It supports a specific mounting subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2. It does not use the FB, CA, CB, or CR mounts found on single-rod variants.
