About the Airtac SAID200 Double Rod Cylinder SAID200BX25S
The AirTAC SAID200X25-S is a double-acting, double-rod ISO 15552 profile cylinder engineered for heavy-duty symmetric actuation. Because the piston rod exits both end covers, the effective annulus area is identical in both directions, yielding an equal force of 15079 N each way 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 -S magnet, this unit supports AirTAC CMSE reed and DMSE electronic solid-state sensors housed within the dual-side barrel grooves. The rod is constructed from SUS304 stainless steel (code B) for enhanced corrosion resistance, and fluid is supplied via PT tapered G3/4 ports. Adjustable air cushions at both ends absorb kinetic energy, though an external lock is required if position holding is needed upon air loss.

Where the Airtac SAID200 Double Rod Cylinder SAID200BX25S Is Used
Heavy Press Transfer
Drives large press feeds requiring identical push and pull forces of 15079 N, using the twin rods to keep heavy tooling perfectly aligned and resistant to rotational torque.
Symmetric Load Shuttling
Shifts substantial payloads between two stations with equal speed and thrust in both directions, leveraging the balanced annulus area for smooth, jerk-free transitions.
Anti-Rotation Guiding
Stabilizes wide lifting platforms or heavy industrial doors, using the double-ended rod geometry to prevent side-loading drift and maintain precise linear tracking.
Is the Airtac SAID200 Double Rod Cylinder SAID200BX25S the Right Cylinder?
Selecting this 200 mm bore cylinder is ideal when an application demands immense bidirectional thrust that remains perfectly balanced, stepping up from a 160 mm bore that provides 9425 N at 0.5 MPa. The SUS304 double-rod design is specifically chosen over a single-rod SAI when the mechanism requires twin-station actuation, dual-side guidance to prevent torsional twist, or rear-rod limit flagging. For drop-in compatibility, match the 200 mm bore, 25 mm stroke, PT G3/4 ports, and the ISO 15552 mounting footprint.
Mounting options for this double-rod variant include Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting the FB, CA, CB, and CR accessories reserved for single-rod models. Because the rear rod protrudes continuously, ensure adequate clearance behind the rear cover. Note that the adjustable end cushions decelerate the piston but do not function as a brake; if the load must be held without live pressure, specify a BSAID clamp-lock or an external pilot-operated check valve.

- ✓ 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 SAID200BX25S FAQ
Because the rod occupies both sides of the piston, the push and pull forces are equal. This 200 mm bore cylinder generates 15079 N in both directions 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 drop it in for other standard profile double-rod cylinders by matching the 200 mm bore, 25 mm stroke, PT G3/4 ports, and utilizing the Basic, FA, LB, or TC mounting interfaces.
