About the Airtac SAID200 Double Rod Cylinder SAID200BX220S
The AirTAC SAID200X220-S is a double-acting, double-rod ISO 15552 profile cylinder engineered for heavy-duty symmetrical motion. Because the piston rod exits both end covers, the effective annulus area is identical on extend and retract, yielding an equal 15079 N of force in each direction at 0.5 MPa. This through-rod geometry provides superior anti-rotation guidance and allows a secondary mechanism or position flag to be driven from the rear.
Configured with a SUS304 stainless steel rod (code B) and an integrated magnet (-S), this 200mm bore unit supports AirTAC CMSE reed and DMSE electronic sensors via the dual-side barrel grooves. It features adjustable air cushioning at both ends (50 mm cushion stroke) to decelerate high kinetic energy loads, operating at speeds of 30-500 mm/s.

Where the Airtac SAID200 Double Rod Cylinder SAID200BX220S Is Used
Symmetric Force Transfer
Drives heavy workpiece carriages requiring identical push and pull thrust, utilizing the equal 15079 N annulus force to prevent motor or linkage backlash.
Anti-Rotation Slides
The twin-rod architecture resists torsional twisting on heavy vertical lifts, maintaining precise load orientation without external linear bearings.
Dual-Station Actuation
Mounts the primary tool on the front rod end and a secondary cam or position flag on the rear protruding rod to trigger DMSE electronic sensors remotely.
Is the Airtac SAID200 Double Rod Cylinder SAID200BX220S the Right Cylinder?
Selecting this 200mm bore cylinder is appropriate when an application demands massive bidirectional force that a single-rod SAI cannot balance. If the 15079 N output at 0.5 MPa exceeds requirements, stepping down to the 160mm bore yields 9425 N both ways. Conversely, if you need less force, the 125mm bore provides 5734 N. The SAID200X220-S uses PT tapered port threads (G3/8) and accepts mounting accessories from the ISO 15552 double-rod subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR).
With a 220mm stroke, the extended rod length requires careful alignment to prevent rod-bearing bending under high side loads; utilize an external guide rail for heavy or off-center masses. Note that the adjustable air cushioning only decelerates the piston near stroke end and does not hold the load. If pneumatic pressure is lost, the cylinder will drift; for position holding, consider an external rod lock or the AirTAC BSAID clamp-lock variant.

- ✓ 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 SAID200BX220S FAQ
Because it is a double-rod cylinder, the force is identical in both extend and retract directions. It provides 15079 N at 0.5 MPa, 21110 N at 0.7 MPa, and 27141 N at 0.9 MPa.
Yes, the SAID200X220-S is dimensionally interchangeable per ISO 15552 mounting dimensions. It is a drop-in replacement for other ISO 15552 profile double-rod cylinders, provided you account for the rear rod protrusion clearance.
