About the Airtac SAID80 Double Rod Cylinder SAID80BX325S
The AirTAC SAID80X325-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 325mm stroke and an 80mm bore. Because the piston rod exits both end covers, the annular area is identical on both sides, yielding exactly 2268N of force at 0.5 MPa in both extend and retract directions. This symmetric thrust makes it ideal for mechanisms requiring equal push and pull dynamics.
This variant includes a magnet for CMSE reed and DMSE electronic sensors, utilizing the dual-side sensor grooves machined into the extruded aluminum barrel. The rods are constructed from SUS304 stainless steel for enhanced corrosion resistance, and fluid connections use PT tapered threads. A variable air cushion at both ends decelerates the piston near stroke end, though it will not hold a load if air pressure is lost.

Where the Airtac SAID80 Double Rod Cylinder SAID80BX325S Is Used
Symmetric Force Transfer
Drives shuttles or transfer carriages requiring identical push and pull thrust, leveraging the 2268N both-way output to maintain consistent momentum in both directions.
Anti-Rotation Slides
Guides heavy vertical lifting slides or workpieces without twisting, using the twin-rod architecture to resist rotational torque better than a single-rod cylinder.
Dual-Side Actuation
Mounts the primary workpiece on the front rod and a position flag on the rear rod, using the integrated magnet with DMSE sensors to track mid-stroke positioning accurately.
Is the Airtac SAID80 Double Rod Cylinder SAID80BX325S the Right Cylinder?
Select this 80mm bore model when an application demands 2268N of symmetric force at 0.5 MPa, stepping up from the 63mm bore (1402N) or down from the 100mm bore (3681N). A double-rod design is preferred over a single-rod SAI when the mechanism requires dual-side guidance to prevent rotation, or when a rear position flag and cam must be actuated simultaneously from the opposite end. For drop-in compatibility, match the 80mm bore, 325mm stroke, PT G3/8 port, and mounting accessory (Basic, FA, LB, TC, FTC, TCM1, or TCM2).
Because the 325mm stroke is relatively long, the unsupported rod length increases susceptibility to bending under side loads. Utilizing an external guide mechanism is recommended to prevent premature rod-bearing wear. Note that this cylinder drifts when air is exhausted; for position holding without live pressure, consider an external rod lock or the BSAID clamp-lock variant.
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 SAID80 Double Rod Cylinder SAID80BX325S FAQ
Because the rod occupies both sides of the piston, the effective area is equal in both directions. It provides 2268N at 0.5 MPa, 3175N at 0.7 MPa, and 4082N at 0.9 MPa for both extend and retract strokes.
Yes, the SAID80X325-S is dimensionally interchangeable per ISO 15552 mounting interface dimensions. It uses a standard profile barrel design and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, allowing direct replacement of other ISO 15552 double-rod cylinders.
