Airtac SAID200 Double Rod Cylinder SAID200BX25
The AirTAC Airtac SAID200 Double Rod Cylinder SAID200BX25 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 25mm stroke, G3/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAID200 Double Rod Cylinder SAID200BX25
The AirTAC SAID200X25 is a double-acting, double-rod profile cylinder built to ISO 15552 mounting dimensions. A single piston drives a SUS304 stainless steel rod out of both end covers, yielding an effective annulus area that is identical on extend and retract. Consequently, it generates an equal 15079 N of thrust and pull force at 0.5 MPa in either direction.
Because the rod exits both covers, the rear end can host a cam, position flag, or secondary tool while the front drives the primary workload. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement. Note that while adjustable air cushions decelerate the piston at both ends, this cylinder will drift if air pressure is lost; use a BSAID clamp-lock or external pilot-operated check valve if position holding is required.

Where the Airtac SAID200 Double Rod Cylinder SAID200BX25 Is Used
Symmetric Press Clamping
Drives a heavy press fixture with equal 15079 N clamping and release forces at 0.5 MPa, ensuring consistent pressure on thick metal sheets during fabrication.
Dual-Station Transfer
Uses the through-rod design to move a workpiece on the front end while simultaneously actuating a secondary mechanism or ejector on the rear side.
Anti-Rotation Guiding
Leverages the twin SUS304 rods exiting both covers to maintain strict linear guidance and prevent load rotation on heavy lifting jigs.
Is the Airtac SAID200 Double Rod Cylinder SAID200BX25 the Right Cylinder?
Choose this 200 mm bore when an application demands massive symmetric force, as the SAID200X25 provides 15079 N both ways at 0.5 MPa. If your load requires less thrust, stepping down to the 160 mm bore yields 9425 N under the same pressure, whereas moving up is impossible within this standard range. The twin-rod architecture is selected over a single-rod SAI when the mechanism needs dual-side guidance to prevent rotation or requires actuation and sensing on opposite ends of the machine.
This configuration features PT tapered port threads and lacks a piston magnet, meaning electronic DMSE or reed CMSE switches cannot be used unless retrofitted. Although the 25 mm stroke is short, the 40 mm diameter SUS304 rods provide high stiffness against side loads. For any application approaching the 300 mm stroke threshold or beyond, adding an external guide rail is recommended to prevent rod-bearing bending.

- ✓ 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 SAID200BX25 FAQ
Because the double-rod design subtracts the rod area from both sides of the piston, the extend and retract forces are equal. The SAID200X25 delivers 15079 N at 0.5 MPa, 21110 N at 0.7 MPa, and 27141 N at 0.9 MPa in both directions.
Yes, the SAID200X25 is dimensionally interchangeable per ISO 15552 and accepts standard profile cylinder accessories. However, the SAID series uses a reduced mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2. It omits the FB, CA, CB, and CR brackets found on single-rod variants.
