About the Airtac SAID200 Double Rod Cylinder SAID200BX175S
The AirTAC SAID200X175-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 200 mm bore and 175 mm stroke. Because the piston 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 symmetric thrust makes it ideal for mechanisms requiring identical push and pull dynamics.
Equipped with a SUS304 stainless steel rod and a magnetic piston, this variant supports AirTAC CMSE reed and DMSE solid-state sensors along the dual extruded barrel grooves. The G3/4 PT tapered ports manage high airflow, while the through-rod design allows mounting a cam or position flag on the rear extension for dual-side guidance.

Where the Airtac SAID200 Double Rod Cylinder SAID200BX175S Is Used
Symmetric Press Drive
Drives a heavy forming press where equal 15079 N extend and retract forces at 0.5 MPa ensure consistent material handling during both advance and return strokes.
Dual-Side Transfer System
Uses the through-rod to actuate a primary workpiece on the front while simultaneously driving a synchronized cam or position flag on the rear for anti-rotation guidance.
Heavy-Duty Indexing Lift
Lifts and lowers substantial payloads within the 30-500 mm/s speed range, relying on the SUS304 rod for corrosion resistance in demanding industrial environments.
Is the Airtac SAID200 Double Rod Cylinder SAID200BX175S the Right Cylinder?
Select this 200 mm bore when an application demands massive equal bidirectional force, as stepping down to a 160 mm bore drops the output to 9425 N at 0.5 MPa. The twin-rod architecture is chosen over a single-rod SAI when the load requires strict anti-rotation guidance or a secondary mechanism must be driven from the rear rod end. To configure, specify the 175 mm stroke, G3/4 PT ports, SUS304 rod material, and the -S magnet for CMSE/DMSE sensing.
For strokes of 300 mm or longer, the extended unsupported rod mass induces bending moments on the rod bearing, requiring an external guide to prevent side-load damage. Note that the adjustable air cushions only decelerate the piston near stroke end; this cylinder does not hold a load without live pressure. For position holding, consider a SAIL lock, BSAID clamp-lock, or an external pilot-operated check valve. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 SAID200BX175S FAQ
Because the rod occupies both sides of the piston, the effective area is identical in both directions. It delivers 15079 N at 0.5 MPa, 21110 N at 0.7 MPa, and 27141 N at 0.9 MPa for both extend and retract strokes.
Yes, it is dimensionally interchangeable per ISO 15552 profile cylinder standards. It serves as a drop-in replacement for other ISO 15552 double-rod cylinders, utilizing the standard mounting interface and sharing the SAI barrel footprint.
