About the Airtac SAID200 Double Rod Cylinder SAID200BX175
The AirTAC SAID200X175 is a double-acting, double-rod profile cylinder built to ISO 15552 mounting dimensions. A single piston drives a rod out of both end covers, yielding equal effective areas on extend and retract. This symmetry means the unit generates exactly 15079 N of thrust and pull force at 0.5 MPa in either direction. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting.
This specific configuration uses a SUS304 stainless steel rod, making it highly suitable for environments where corrosion resistance is critical. It features PT tapered port threads and lacks a piston magnet. Because a rod protrudes from the rear cover, you must account for additional clearance at the back of the cylinder to accommodate the moving shaft during operation.

Where the Airtac SAID200 Double Rod Cylinder SAID200BX175 Is Used
Symmetric Force Transfer
Drives heavy material handling gates or indexers where the 15079 N push and pull forces must be perfectly matched to prevent mechanical binding during bidirectional cycles.
Anti-Rotation Slides
Uses the dual-ended rod geometry to guide heavy linear slides without rotational drift, eliminating the need for external guide shafts on large press feeds.
Twin-Station Actuation
Mounts the primary workpiece on the front rod end and a secondary mechanism or mechanical stop on the rear rod end to synchronize two separate operations from one cylinder.
Is the Airtac SAID200 Double Rod Cylinder SAID200BX175 the Right Cylinder?
Choose this 200 mm bore size when an application demands substantial symmetric force, as it provides 15079 N each way at 0.5 MPa. If your load requirements are lower, stepping down to a 160 mm bore yields 9425 N. The twin-rod design is selected over a single-rod SAI when the mechanism requires dual-side guidance to prevent rotation, or when a rear-mounted cam and position flag must be driven simultaneously. Since this is a standard double-acting cylinder, it will drift if air pressure is lost; for position-holding safety, consider a BSAID clamp-lock or an external pilot-operated check valve.
This 175 mm stroke falls within the standard range and is not a made-to-order length. Although the 40 mm rod diameter and M36x2 thread provide excellent rigidity, any stroke of 300 mm or longer increases the risk of rod-bearing bending under side loads. For this 175 mm stroke, side-loading is less severe, but external guides are still recommended if the load is heavy or off-center. Mounting options include the SAID-specific set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR variants found on single-rod cylinders.

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 SAID200BX175 FAQ
Because the double-rod design subtracts the rod area from both sides of the piston, the extend and retract forces are equal. This 200 mm bore cylinder provides 15079 N in both directions at 0.5 MPa, and 21110 N at 0.7 MPa.
Yes, it is dimensionally interchangeable per ISO 15552 profile cylinder standards, serving as a drop-in replacement for other ISO 15552 double-rod cylinders. Note that it uses a PT tapered port thread and a SUS304 stainless steel rod.
