About the Airtac SAID80 Double Rod Cylinder SAID80BX200S
The AirTAC SAID80X200-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 200mm stroke and an 80mm bore. Because the piston rod extends from both end covers, the effective annulus area is identical on extend and retract. This cylinder generates 2268 N of force in both directions at 0.5 MPa, scaling up to 4082 N at 0.9 MPa, ensuring symmetric thrust and speed for demanding transfer tasks.
Equipped with a magnet (-S) for position sensing, it works seamlessly with AirTAC CMSE reed and DMSE electronic switches mounted into the dual-side sensor grooves. The rods are constructed from SUS304 stainless steel (code B) for superior corrosion resistance, and fluid ports feature PT tapered threads. The adjustable air cushions at both ends provide 36mm of deceleration to protect the mechanism at cycle completion.

Where the Airtac SAID80 Double Rod Cylinder SAID80BX200S Is Used
Symmetric Force Transfer
Drives a workpiece on the front rod while simultaneously moving a secondary assembly on the rear rod, utilizing the equal 2268 N thrust and matching speed in both directions.
Anti-Rotation Slides
Leverages the dual SUS304 stainless steel rods exiting both ends to maintain strict linear guidance and prevent mechanical twisting during heavy-load positioning.
Through-Rod Sensing
Uses the integrated magnet with CMSE reed and DMSE electronic switches in the dual sensor grooves to track the rear rod extension for precise end-of-stroke confirmation.
Is the Airtac SAID80 Double Rod Cylinder SAID80BX200S the Right Cylinder?
Choose this 80mm bore when an application demands balanced 2268 N thrust on both strokes and requires a rear-rod extension for mounting a secondary cam, position flag, or driving a separate mechanism. Stepping down to a 63mm bore drops the both-way force to 1402 N, while moving up to a 100mm bore increases it to 3681 N. The twin-rod design inherently resists torsional load and provides superior anti-rotation guidance compared to a single-rod SAI cylinder.
As a dimensionally interchangeable ISO 15552 profile cylinder, it serves as a drop-in replacement for other standard double-rod actuators. It uses a specific mounting accessory set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting FB, CA, CB, and CR brackets. Note that a plain SAID does not hold its load if air pressure is lost; for fail-safe holding, consider an SAIL lock, BSAID clamp-lock, or external rod lock. Since the stroke is 200mm, external guides are recommended to prevent rod-bearing bending under heavy side loads.

- ✓ 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 SAID80BX200S FAQ
Because the rod occupies both sides of the piston, the effective area is equal in both directions. It outputs 2268 N at 0.5 MPa, 3175 N at 0.7 MPa, and 4082 N at 0.9 MPa on both extend and retract strokes.
No, the SAID80X200-S is a double-acting cylinder and will drift if air is exhausted or the valve is centered. The adjustable air cushions only decelerate the piston near the stroke ends; they do not lock the load. For position holding, an SAIL or BSAID lock cylinder is required.
