About the Airtac SAID50 Double Rod Cylinder SAID50AX125
The AirTAC SAID50X125 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 50mm bore and 125mm stroke. Because the piston rod extends from both end covers, the effective annulus area is identical on the extend and retract strokes. This provides an equal force of 825 N in both directions at 0.5 MPa, ensuring perfectly symmetric motion control.
Equipped with a SUS420J2 stainless steel rod (material code A) and PT tapered port threads, this unit offers robust resistance to micro-corrosion. The rear rod protrusion allows you to mount a secondary cam or position flag, while the extruded aluminum barrel integrates sensor grooves on both sides for flexible switch placement.

Where the Airtac SAID50 Double Rod Cylinder SAID50AX125 Is Used
Symmetric Transfer
Provides identical push and pull thrust for conveying workpieces between two stations without needing pressure adjustments.
Anti-Rotation Slides
The twin-rod architecture inherently resists torsional twisting, keeping guided loads perfectly stable during vertical lifts.
Rear-Rod Sensing
Mounts a mechanical flag or cam on the rear rod extension to trigger external limit switches independently of the front tool.
Is the Airtac SAID50 Double Rod Cylinder SAID50AX125 the Right Cylinder?
Select this 50mm bore when an application demands equal push and pull forces, such as symmetric transfer or anti-rotation slides. If your project requires less force, the 40mm neighbor provides 528 N both ways at 0.5 MPa; stepping up to the 63mm bore yields 1402 N. Choose the double-rod SAID over a single-rod SAI when you need dual-side guidance or a rear-rod output for secondary mechanisms.
This cylinder uses a reduced ISO 15552 mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR brackets. Note that the adjustable air cushions only decelerate the piston near stroke end; they do not hold the load. If air pressure drops, the piston will drift, so add an external pilot-operated check valve for position holding.
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 SAID50AX125 FAQ
Because it is a double-rod cylinder, the push and pull forces are equal. It generates 825 N both ways at 0.5 MPa, 1154 N at 0.7 MPa, and 1484 N at 0.9 MPa.
Yes, it is dimensionally interchangeable with ISO 15552 profile cylinders. It supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 brackets, but omits FB, CA, CB, and CR styles.
