About the Airtac SAID200 Double Rod Cylinder SAID200X80S
The AirTAC SAID200X80-S is a double-acting, double-rod ISO 15552 profile cylinder engineered for heavy-duty symmetrical actuation. Because a carbon steel rod protrudes from both end covers, the effective piston area is identical in each direction, yielding an equal force of 15079 N on both extend and retract at 0.5 MPa. The integrated magnet (-S) enables precise end-of-stroke detection using AirTAC CMSE reed or DMSE electronic solid-state switches housed within the dual lateral sensor grooves.
This through-rod architecture provides superior anti-rotation guidance and allows a secondary mechanism or cam to be driven from the rear rod end. Fluid compatibility is limited to filtered air, operating between 0.15-1.0 MPa. It features adjustable air cushioning at both ends to decelerate the massive 200 mm piston smoothly, while the PT tapered port threads ensure a robust, leak-free connection.

Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAID200 Double Rod Cylinder SAID200X80S Is Used
Symmetric Force Transfer
Drives heavy workloads requiring identical push and pull power, utilizing the 15079 N bidirectional output to move massive platens without force imbalance.
Twin-Station Actuation
Simultaneously operates two separate mechanisms by mounting the primary tool on the front rod and a secondary cam or flag on the rear protruding rod end.
Anti-Rotation Slides
Keeps heavy guided loads perfectly stable during transit, using the dual-ended rod architecture to resist torsional twisting and maintain precise alignment.
Is the Airtac SAID200 Double Rod Cylinder SAID200X80S the Right Cylinder?
Selecting this 200 mm bore model is ideal when an application demands immense bidirectional force that remains perfectly balanced, a distinct advantage over the single-rod SAI variant where push and pull forces differ. If the 15079 N output at 0.5 MPa exceeds requirements, stepping down to the 160 mm bore offers 9425 N, providing a more compact footprint while retaining the double-rod benefits. Conversely, if your mechanism requires holding a load without live air pressure, a plain SAID will drift; you should pivot to the BSAID clamp-lock series or employ an external pilot-operated check valve.
For this specific 80 mm stroke configuration, the side-load risk is minimal compared to longer strokes, but the substantial 40 mm rod diameter and M36x2 thread easily handle high bending stresses. Mounting choices are restricted to the SAID subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2. Ensure you provision adequate rear clearance, as the through-rod requires space to extend behind the cylinder body.

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 SAID200 Double Rod Cylinder SAID200X80S FAQ
Because it is a double-rod cylinder, the force is identical in both directions. It provides 15079 N at 0.5 MPa, 21110 N at 0.7 MPa, and 27141 N at 0.9 MPa.
Yes, it is dimensionally interchangeable per ISO 15552 standards. It serves as a direct replacement for other ISO 15552 profile double-rod cylinders, provided your mounting hardware uses the Basic, FA, LB, TC, FTC, TCM1, or TCM2 interface.
