About the Airtac SAID100 Double Rod Cylinder SAID100AX450S
The AirTAC SAID100X450-S is a double-acting, double-rod ISO 15552 profile cylinder. Because the piston rod exits both end covers, the effective annulus area is identical in both directions, yielding an equal extend and retract force of 3681 N at 0.5 MPa. This through-rod design allows driving a primary workpiece on one end while mounting a position flag or cam on the rear rod for external sensing.
This specific configuration includes a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and a magnet for use with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel features sensor grooves on both sides, and adjustable air cushions at both ends decelerate the piston near stroke end to minimize impact.

Where the Airtac SAID100 Double Rod Cylinder SAID100AX450S Is Used
Symmetric Transfer Unit
Drives a transfer carriage with equal push and pull force, using the twin rods to maintain load balance and prevent binding during rapid direction changes.
Anti-Rotation Slide
The dual-rod construction resists torsional twist, keeping a vertical lifting slide perfectly aligned without needing external linear bearings.
Twin-Station Actuation
Mounts a primary forming tool on the front rod end and a secondary cam or limit flag on the rear rod to trigger a sequential operation in the same stroke.
Is the Airtac SAID100 Double Rod Cylinder SAID100AX450S the Right Cylinder?
Choose this 100mm bore cylinder when an application requires symmetric force and speed, as it provides 3681 N in both directions at 0.5 MPa. If your mechanism needs less force, stepping down to an 80mm bore yields 2268 N each way; if more force is required, a 125mm bore offers 5734 N. The double-rod architecture is selected over a single-rod SAI when dual-side guidance, anti-rotation stability, or rear-rod actuation is critical.
This model uses a PT G1/2 port and includes the -S magnet option. At 450mm stroke, the unsupported load increases bending stress on the rod bearings, so an external guide rail is recommended to handle side loads. Note that a plain SAID does not hold its position if air pressure is lost; for dead-end holding, consider a SAIL or BSAID clamp-lock variant. It is dimensionally interchangeable per ISO 15552 and uses the reduced SAID mounting 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 SAID100 Double Rod Cylinder SAID100AX450S FAQ
Because the rod area is subtracted on both sides, the SAID100X450-S delivers equal force in both extend and retract directions. It provides 3681 N at 0.5 MPa, 5153 N at 0.7 MPa, and 6626 N at 0.9 MPa.
Yes, the SAID100X450-S is a profile cylinder with standard ISO 15552 mounting interface dimensions, making it a drop-in replacement for other ISO 15552 double-rod cylinders. It uses the standard SAID mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and excludes single-rod only accessories like FB or CA.
