About the Airtac SAID200 Double Rod Cylinder SAID200BX80S
The AirTAC SAID200X80-S is a double-acting, double-rod ISO 15552 profile cylinder engineered for heavy-duty symmetric actuation. Because a SUS304 stainless steel rod exits both ends, the effective piston area is identical in each direction, yielding an equal extend and retract force of 15079 N at 0.5 MPa. This through-rod architecture provides superior anti-rotation guidance and allows a secondary mechanism or position flag to be driven from the rear.
Equipped with a factory-installed magnet (-S), this 200 mm bore unit seamlessly integrates with AirTAC CMSE reed and DMSE electronic solid-state sensors mounted along the dual-side barrel grooves. The cylinder utilizes PT tapered port threads (G3/4) and adjustable air cushioning at both ends to decelerate massive loads smoothly over its 80 mm stroke.

Where the Airtac SAID200 Double Rod Cylinder SAID200BX80S Is Used
Symmetric Pressing
Ideal for heavy-duty pressing operations requiring identical force and speed on both the extend and retract strokes to maintain precise load balance.
Dual-Station Transfer
Drives two synchronized workstations simultaneously by mounting a tool on the front rod end and a secondary actuator or flag on the rear rod.
Anti-Rotation Slides
The twin-rod design inherently resists torsional deflection, providing strict linear guidance for heavy lifting slides without external guide rails.
Is the Airtac SAID200 Double Rod Cylinder SAID200BX80S the Right Cylinder?
Select this 200 mm bore model when an application demands immense, perfectly balanced force in both travel directions, stepping up from a 160 mm bore that provides 9425 N at 0.5 MPa. The twin-rod layout is specifically chosen over a single-rod SAI when the load requires strict anti-rotation control, dual-side guidance, or rear-rod position sensing. To ensure a precise drop-in replacement, verify the 80 mm stroke, G3/4 PT ports, and the required ISO 15552 mounting accessory from the available Basic, FA, LB, TC, FTC, TCM1, and TCM2 set.
Note that the adjustable air cushions only decelerate the piston near stroke end; they do not hold the load. If the mechanism must maintain its position without live air pressure, an external pilot-operated check valve or a related locking type like BSAID is required. Because the rear rod protrudes continuously, you must allocate extra clearance at the back of the cylinder for the rod to travel freely.

- ✓ 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 SAID200 Double Rod Cylinder SAID200BX80S 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. You can use it as a drop-in replacement for other ISO 15552 profile double-rod cylinders, provided your mounting hardware matches the Basic, FA, LB, TC, FTC, TCM1, or TCM2 interfaces.
