About the Airtac SAID100 Double Rod Cylinder SAID100AX450
The AirTAC SAID100X450 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 100mm bore and 450mm stroke. Because twin rods occupy both piston sides, the annulus area is identical in each direction, yielding equal push and pull forces of 3681N at 0.5MPa. A rod exits both end covers, making it dimensionally interchangeable with other ISO 15552 double-rod units.
This variant uses a SUS420J2 stainless steel rod (material code A) for superior corrosion resistance. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. Note that the rear rod protrudes during operation, requiring extra clearance, and the PT tapered port thread ensures a robust pneumatic seal.

Where the Airtac SAID100 Double Rod Cylinder SAID100AX450 Is Used
Symmetric Transfer
Drives a transfer carriage with equal push and pull force, ensuring consistent momentum and cycle times regardless of travel direction.
Anti-Rotation Slides
The twin-rod design resists torsional twist, keeping the attached tool plate perfectly guided during high-speed machining operations.
Rear-Side Sensing
Mounts a physical cam or position flag on the rear rod end to trigger external mechanical limit switches away from the primary work area.
Is the Airtac SAID100 Double Rod Cylinder SAID100AX450 the Right Cylinder?
Select this 100mm bore when an application demands symmetric thrust of 3681N in both directions, such as twin-station actuation or anti-rotation slides. If your load is lighter, stepping down to the 80mm bore provides 2268N each way at 0.5MPa. For heavier demands, the 125mm bore offers 5734N. Choose the SAID double-rod over a single-rod SAI when you need to mount a cam or position flag on the rear extension, or to guide the load against rotation.
At 450mm stroke, the unsupported rod length increases, raising the risk of rod-bearing bending under side loads; use an external guide rail to support the workpiece. This cylinder uses the reduced SAID mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR accessories. Plain SAID cylinders do not hold position if air is lost; for drop prevention, consider a BSAID clamp-lock or external 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 SAID100 Double Rod Cylinder SAID100AX450 FAQ
Because it is a double-rod cylinder, the effective area is the same on both sides. It delivers an equal push and pull force of 3681N at 0.5MPa, 5153N at 0.7MPa, and 6626N at 0.9MPa.
Yes, it is dimensionally interchangeable per ISO 15552. However, the SAID series uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits the FB, CA, CB, and CR mounts found on single-rod cylinders.
