About the Airtac SAID125 Double Rod Cylinder SAID125AX190
The AirTAC SAID125X190 is a double-acting, double-rod profile cylinder conforming to ISO 15552 mounting dimensions. Because a rod exits both ends, the annulus area is identical on extend and retract, yielding exactly 5734 N of force each way at 0.5 MPa. This symmetric output is ideal for mechanisms requiring equal push and pull dynamics.
This unit features a SUS420J2 stainless steel rod (option A) for superior corrosion resistance and a PT tapered port thread. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. Note that the rear rod protrudes from the back cover, requiring additional clearance space in your machine layout.

Where the Airtac SAID125 Double Rod Cylinder SAID125AX190 Is Used
Symmetric Transfer
Drives a transfer carriage with equal push and pull force, maintaining consistent speed and momentum in both directions without requiring pressure compensations.
Anti-Rotation Slides
The twin rods prevent piston rotation, providing precise linear guidance for heavy tooling mounts that require strict orientation control.
Dual-Station Actuation
Mount a primary workpiece on the front rod end and a secondary cam or position flag on the rear rod to trigger external limit sensors.
Is the Airtac SAID125 Double Rod Cylinder SAID125AX190 the Right Cylinder?
Choose this 125 mm bore over the smaller 100 mm (3681 N at 0.5 MPa) when your application demands higher bidirectional force, or step up to the 160 mm bore (9425 N) for heavier loads. The double-rod design is selected over a single-rod SAI when you need dual-side guidance, anti-rotation stability, or a rear rod to drive a secondary mechanism. Since the stroke is 190 mm, side-load is moderate, but external guides are recommended if the load is heavy. Remember that the adjustable air cushions only decelerate the piston near stroke ends; they do not hold a load without live pressure. For position holding, consider an external pilot-operated check valve. This cylinder is dimensionally interchangeable per ISO 15552, accepting PT ports and mounting accessories from the reduced SAID set (Basic, FA, LB, TC, FTC, TCM1, TCM2).
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 SAID125 Double Rod Cylinder SAID125AX190 FAQ
Because it is a double-rod cylinder, the push and pull forces are identical. It generates 5734 N in both directions at 0.5 MPa, 8028 N at 0.7 MPa, and 10321 N at 0.9 MPa.
Yes, it is dimensionally interchangeable with ISO 15552 profile cylinders. However, SAID uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR accessories found on single-rod variants.
