About the Airtac SAID100 Double Rod Cylinder SAID100AX650S
The AirTAC SAID100X650-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 100mm bore and 650mm stroke. Because the piston rod exits both end covers, the annular area is identical on extend and retract, yielding a perfectly symmetric thrust of 3681 N each way at 0.5 MPa. This through-rod design is ideal for applications requiring dual-side guidance, anti-rotation stability, or mounting a secondary mechanism and a position flag on the rear rod.
Equipped with a -S magnet, this unit supports AirTAC CMSE reed and DMSE electronic solid-state sensors housed within the extruded aluminum barrel grooves on both sides. The rod is constructed from SUS420J2 stainless steel (material code A) for enhanced corrosion resistance, and fluid connections use PT tapered threads. Adjustable air cushions at both ends decelerate the piston near stroke limits, though they do not function as a locking brake if air pressure is lost.

Where the Airtac SAID100 Double Rod Cylinder SAID100AX650S Is Used
Symmetric Transfer Unit
Drives a transfer carriage with equal push and pull force, using the twin rods to maintain precise alignment and prevent binding over the 650mm travel.
Twin-Station Actuation
Mounts individual workpieces or tooling on opposite rod ends to operate two synchronized mechanisms from a single pneumatic motion input.
Rear-Cam Sensing
Utilizes the protruding rear rod to carry a cam for DMSE solid-state sensors, verifying end-of-stroke position without exposing the primary work area.
Is the Airtac SAID100 Double Rod Cylinder SAID100AX650S the Right Cylinder?
Choose this 100mm bore when an application demands matched push and pull forces alongside high torsional rigidity, stepping up from a 80mm bore (2268 N at 0.5 MPa) or down from a 125mm bore (5734 N at 0.5 MPa). The double-rod architecture is selected over a single-rod SAI when the mechanism needs to drive twin stations, prevent load rotation, or track position from the rear. For this 650mm stroke, the long unsupported rod mandates an external guide to prevent excessive side-load bending on the rod bearings.
This cylinder serves as a drop-in replacement for other ISO 15552 double-rod profile cylinders, matching the 100mm bore footprint, 650mm stroke, G1/2 port, and standard mounting accessories (Basic, FA, LB, TC, FTC, TCM1, TCM2). Note that a plain SAID cylinder will drift and cannot hold a load if air is exhausted or valve is centered; integrate an external pilot-operated check valve or select a BSAID clamp-lock cylinder for fail-safe 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 SAID100 Double Rod Cylinder SAID100AX650S FAQ
It provides 3681 N of force at 0.5 MPa, 5153 N at 0.7 MPa, and 6626 N at 0.9 MPa. Because it is a double-rod cylinder, this thrust is exactly the same in both the extend and retract directions.
No, the adjustable air cushions only decelerate the piston at the end of stroke and do not lock the position. If you need to hold a load without live air pressure, you must use an external rod lock, a pilot-operated check valve, or switch to an AirTAC BSAID double-rod clamp-lock cylinder.
