About the Airtac SAID80 Double Rod Cylinder SAID80X900
The AirTAC SAID80X900 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 900 mm stroke and a 25 mm rod extending from both end covers. Because the piston area is equally reduced by the twin rods on each side, it generates exactly 2268 N of thrust and pull force at 0.5 MPa, ensuring symmetric output and velocity in both directions. The extruded aluminum barrel includes integrated sensor grooves on both lateral sides for flexible mounting of position switches.
This 80 mm bore variant uses a G3/8 port and an M20x1.5 rod thread, providing a robust interface for heavy loads. Without a magnet specified, it is configured for external physical limit flags rather than internal reed or electronic sensing. The rear rod extension is highly useful for driving a secondary mechanism or mounting a cam, while the adjustable air cushions at both ends absorb kinetic energy over the long 900 mm travel.

Where the Airtac SAID80 Double Rod Cylinder SAID80X900 Is Used
Symmetric Force Transfer
Drives a heavy machining fixture where the 2268 N output at 0.5 MPa must be identical in both advance and retract motions to maintain process stability.
Twin-Station Actuation
Uses the protruding rear rod to operate a secondary synchronized mechanism or position flag on the opposite side of the main workpiece.
Anti-Rotation Slides
Keeps a long 900 mm stroke slide guided against rotational torque without relying solely on external linear bearings, thanks to the dual-rod anchoring.
Is the Airtac SAID80 Double Rod Cylinder SAID80X900 the Right Cylinder?
Choose this 80 mm bore when an application demands identical push and pull forces across a 900 mm span, stepping up from a 63 mm bore (which provides 1402 N at 0.5 MPa) to handle heavier symmetric loads. The double-rod design is selected over a single-rod SAI when the mechanism requires superior anti-rotation resistance, dual-side work mounting, or a rear rod to actuate a secondary station. To match this ISO 15552 footprint for a drop-in replacement, verify the 80 mm bore, 900 mm stroke, G3/8 PT port, and choose from the available SAID mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2).
Because the stroke is 900 mm, the unsupported piston rod is highly susceptible to bending under side loads; utilizing an external guide rail is strongly recommended to prevent premature rod-bearing wear. Furthermore, the adjustable air cushions only decelerate the piston near the stroke ends and do not function as a brake; if the load must be held in place without sustained air pressure, an external pilot-operated check valve or a related locking type like BSAID is required.

- ✓ 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 SAID80X900 FAQ
Because the double-rod design occupies piston area on both sides, the extend and retract forces are equal. It outputs 2268 N at 0.5 MPa, 3175 N at 0.7 MPa, and 4082 N at 0.9 MPa in both directions.
Yes, the SAID80X900 is dimensionally interchangeable per ISO 15552 profile cylinder standards, matching the standard 80 mm bore, 900 mm stroke, and G3/8 port footprint for drop-in replacement.
