About the Airtac SAID100 Double Rod Cylinder SAID100BX325
The AirTAC SAID100X325 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 100mm bore and 325mm stroke. Because the twin SUS304 stainless steel rods occupy both piston faces, the annulus area is identical in each direction, yielding an equal extend and retract force of 3681 N at 0.5 MPa. A rod exits both end covers, allowing you to mount a primary workpiece on the front and a position flag or secondary cam on the rear.
This model uses a PT G1/2 port and adjustable air cushions at both ends to decelerate the piston smoothly. The extruded aluminum barrel includes sensor grooves on both sides for mounting CMSE reed or DMSE electronic switches. Note that a plain SAID cylinder will drift and cannot hold a load if air pressure is lost; for position holding without live pressure, consider an external rod lock or the related BSAID clamp-lock series.

Where the Airtac SAID100 Double Rod Cylinder SAID100BX325 Is Used
Symmetric Transfer Slide
Drives a transfer carriage with equal push and pull force of 3681 N at 0.5 MPa, ensuring consistent cycle times in both directions without speed variation.
Anti-Rotation Lifter
Uses the dual SUS304 rods exiting both ends to guide a lifting platform securely, preventing mechanical twist and maintaining precise vertical alignment.
Twin-Station Actuator
Mounts the primary tool on the front rod end and a rear position flag on the opposite rod end to trigger DMSE electronic sensors for dual-station timing.
Is the Airtac SAID100 Double Rod Cylinder SAID100BX325 the Right Cylinder?
Choose this 100mm bore when an application requires symmetric thrust in both directions, such as a transfer mechanism that does equal work on push and pull strokes. If your project needs less force, stepping down to the 80mm bore yields 2268 N each way at 0.5 MPa, while the larger 125mm bore provides 5734 N. The double-rod design is specifically selected over a single-rod SAI when the mechanism requires dual-side guidance to prevent rotation or needs rear-rod clearance for a secondary actuation station.
Because the 325mm stroke exceeds 300mm, the extended unsupported rod length increases the risk of side-load bending on the rod bearing; use an external guide rail to support heavy loads. This cylinder is dimensionally interchangeable per ISO 15552, serving as a drop-in replacement for other ISO 15552 double-rod cylinders. Configuration details include the PT G1/2 port, Basic/FA/LB/TC/FTC/TCM1/TCM2 mounting accessories, and no internal magnet specified.
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 SAID100BX325 FAQ
The SAID100X325 provides an equal force of 3681 N in both extend and retract directions at 0.5 MPa, and 5153 N at 0.7 MPa, because the double-rod design balances the effective piston area.
No, the adjustable air cushions only decelerate the piston near stroke end and do not act as a brake. The cylinder will drift if air is exhausted; use an external pilot-operated check valve or the BSAID clamp-lock series for position holding.
