About the Airtac SAID200 Double Rod Cylinder SAID200BX180S
The AirTAC SAID200X180-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 200 mm bore and 180 mm stroke. Because twin rods exit both end covers, the annulus area is identical on extend and retract, yielding exactly 15079 N of force at 0.5 MPa in either travel direction. The -S suffix adds a magnet for precise position detection.
This variant uses SUS304 stainless steel rods for superior corrosion resistance and ships with PT G3/4 port threads. The extruded aluminum barrel includes sensor grooves on both sides, allowing you to mount CMSE reed or DMSE solid-state switches wherever is most accessible for your wiring.

Where the Airtac SAID200 Double Rod Cylinder SAID200BX180S Is Used
Symmetric Pressing
Drives heavy stamping or pressing dies where equal 15079 N force is mandatory on both the downward extend and upward retract strokes.
Twin-Station Transfer
Mounts a workpiece clamp on the front rod end and a synchronized ejector cam on the rear rod end to actuate two separate stations simultaneously.
Anti-Rotation Guidance
Utilizes the dual through-rods to keep heavy 200 mm bore loads perfectly guided against twisting forces without requiring external linear rails.
Is the Airtac SAID200 Double Rod Cylinder SAID200BX180S the Right Cylinder?
Choose this 200 mm bore when you need massive symmetric force, stepping up from the 160 mm class which provides 9425 N at 0.5 MPa. The double-rod architecture is essential over a single-rod SAI when your mechanism requires dual-side guidance to prevent rotation, or when you need to drive a cam and position flag out the rear end cover while the primary tooling operates on the front. Remember that air cushions only decelerate the piston near stroke end; this cylinder will drift if air pressure is lost, so use an external pilot-operated check valve if you must hold a suspended load.
For drop-in compatibility, this model is dimensionally interchangeable per ISO 15552. It uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB and CR accessories. Even at 180 mm stroke, the protruding rear rod demands extra clearance in your machine envelope.
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 SAID200BX180S FAQ
It delivers 15079 N at 0.5 MPa, 21110 N at 0.7 MPa, and 27141 N at 0.9 MPa. Because it is a double-rod cylinder, the extend and retract forces are exactly equal.
It uses a subset of SAI mounts (Basic, FA, LB, TC, FTC, TCM1, TCM2). It omits FB, CA, CB and CR because the rear rod protrudes from the back cover.
