About the Airtac SAID200 Double Rod Cylinder SAID200BX30S
The AirTAC SAID200X30-S is a double-acting, double-rod ISO 15552 profile cylinder engineered for heavy-duty symmetric actuation. Because a rod exits both end covers, the annulus area is identical on extend and retract, yielding exactly 15079 N of force each way at 0.5 MPa. This through-rod geometry provides superior anti-rotation stability and allows a secondary mechanism or position flag to be driven from the rear.
Equipped with a -S magnet, this model supports AirTAC CMSE reed and DMSE electronic sensors along the dual side grooves. It features a robust SUS304 stainless steel rod, PT tapered ports, and adjustable air cushioning at both ends to decelerate the massive piston smoothly.

Where the Airtac SAID200 Double Rod Cylinder SAID200BX30S Is Used
Heavy Press Tonnage
Ideal for massive forming or press operations requiring identical push and pull forces to maintain perfectly balanced tooling kinematics.
Symmetric Transfer Unit
Drives dual-sided material handling stations simultaneously, using the twin rods to synchronize heavy payload movement without twisting.
Rear-Cam Actuation
The protruding rear rod end mounts a cam or limit flag, triggering external DMSE electronic sensors to confirm stroke completion in compact cells.
Is the Airtac SAID200 Double Rod Cylinder SAID200BX30S the Right Cylinder?
Select this 200 mm bore when an application demands immense bidirectional force that a single-rod SAI cannot symmetrically provide. If 15079 N is excessive, stepping down to the 160 mm bore offers 9425 N at 0.5 MPa. Conversely, if higher dynamics are needed, remember this 200 mm bore is limited to a 30-500 mm/s speed range. The short 30 mm stroke minimizes rod-bearing bending stress, but external guidance is still recommended for heavy loads.
This cylinder uses the reduced SAID mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting the FB, CA, CB, and CR brackets found on single-rod variants. It is dimensionally interchangeable per ISO 15552. Note that a plain SAID does not hold its position if air pressure is lost; for dead-load holding, consider an external pilot-operated check valve or the BSAID clamp-lock series.
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 SAID200 Double Rod Cylinder SAID200BX30S FAQ
Because the rod occupies both sides of the piston, the effective area is identical in both directions. It provides 15079 N of force both extending and retracting at 0.5 MPa, and 21110 N at 0.7 MPa.
Yes, it is dimensionally interchangeable with standard ISO 15552 profile cylinders. However, the SAID series uses a specific mounting subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2. It does not support the FB, CA, CB, or CR brackets.
