About the Airtac SAID200 Double Rod Cylinder SAID200BX800S
The AirTAC SAID200X800-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a substantial 800 mm stroke. Because the twin SUS304 stainless steel rods occupy both sides of the piston, the effective annulus area is identical in both directions. This generates an equal push and pull force of 15079 N at 0.5 MPa, ensuring perfectly symmetric thrust and speed for heavy-duty cycles.
Equipped with a magnet for position sensing, the rear rod end can simultaneously drive a secondary mechanism or mount a limit flag while the front rod handles the primary load. The extruded aluminum barrel includes sensor grooves on both sides for CMSE reed and DMSE electronic switches. It uses PT tapered port threads (G3/4) and adjustable air cushions at both ends to decelerate the massive 200 mm piston near stroke limits.

Where the Airtac SAID200 Double Rod Cylinder SAID200BX800S Is Used
Symmetric Force Transfer
Drives heavy moving platens that require identical 15079 N push and pull forces, ensuring perfectly balanced momentum transfer without asymmetric speed drift.
Twin-Station Actuation
Mounts the primary workpiece on the front rod and a secondary cam or position flag on the rear rod to trigger external sequencing switches during the 800 mm cycle.
Anti-Rotation Slides
Uses the dual SUS304 rods to guide heavy vertical loads, preventing torsional twist and maintaining precise alignment over long linear strokes.
Is the Airtac SAID200 Double Rod Cylinder SAID200BX800S the Right Cylinder?
Choose this 200 mm bore model when an application demands immense equal-force transfer in both directions, such as synchronizing heavy platens. If you need less force, stepping down to a 160 mm bore yields 9425 N each way at 0.5 MPa, whereas this 200 mm cylinder provides 15079 N. The double-rod design is selected over a single-rod SAI when twin-side guidance, anti-rotation stability, or rear-rod cam actuation is required.
This cylinder uses PT tapered ports and supports the reduced SAID mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). Note that air cushions only decelerate the piston; they do not hold a load. If the machine loses air pressure, the piston will drift, requiring an external rod lock or a SAIL/BSAID variant for true position holding. At 800 mm stroke, the long unsupported rod span demands an external guide to prevent rod-bearing bending under side loads. It is dimensionally interchangeable per ISO 15552.

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 SAID200BX800S FAQ
Because it is a double-rod cylinder, the push and pull forces are equal. It delivers 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. It serves as a drop-in replacement for other ISO 15552 profile double-rod cylinders, provided your mounting accessory falls within the Basic, FA, LB, TC, FTC, TCM1, or TCM2 set.
