About the Airtac SAID200 Double Rod Cylinder SAID200BX300S
The AirTAC SAID200X300-S is a double-acting, double-rod profile cylinder compliant with ISO 15552 mounting dimensions. A single piston propels a SUS304 stainless steel rod out of both end covers, yielding 15079 N of thrust and pull force at 0.5 MPa. Because the annular area is identical on both sides, extend and retract forces are perfectly equal.
This unit includes a magnetic piston (-S) for position sensing with CMSE reed or DMSE electronic switches. The extruded aluminum barrel features dual sensor grooves. With PT tapered port threads and adjustable air cushions at both ends, it offers a robust drop-in replacement for other ISO 15552 double-rod cylinders.

Where the Airtac SAID200 Double Rod Cylinder SAID200BX300S Is Used
Symmetric Force Transfer
Drives heavy push-and-pull workstations with identical 15079 N force in both directions, preventing speed variations between extend and retract cycles.
Anti-Rotation Slides
Twin SUS304 rods exiting both end covers provide exceptional torsional rigidity, keeping heavy guided loads from twisting during transit.
Rear-Sensing Automation
Uses the -S magnet and rear protruding rod to trigger DMSE electronic sensors, tracking position from the opposite side of the main work area.
Is the Airtac SAID200 Double Rod Cylinder SAID200BX300S the Right Cylinder?
Select this 200 mm bore when an application requires 15079 N of symmetrical force at 0.5 MPa, stepping up from a 160 mm bore that provides 9425 N. The twin-rod design is chosen over a single-rod SAI when the mechanism needs dual-side guidance to prevent rotation, or when a rear rod end is required to mount a secondary cam or position flag.
At a 300 mm stroke, the long unsupported rod bearing is prone to bending under side loads; utilize an external guide rail to prevent premature wear. This SAID model uses the Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounting set, omitting FB and CA options. Note that air cushions only decelerate the piston near stroke end; to hold a load without live pressure, use a BSAID clamp-lock or external rod lock.
Quick checklist
- ✓ 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 SAID200BX300S FAQ
It provides 15079 N of force at 0.5 MPa, 21110 N at 0.7 MPa, and 27141 N at 0.9 MPa. Because it is a double-rod cylinder, the annular piston area is identical on both sides, meaning extend and retract forces are exactly equal.
Yes, the SAID200X300-S is dimensionally interchangeable per ISO 15552 profile cylinder standards. It shares the exact mounting footprint of other double-rod ISO 15552 cylinders, allowing a drop-in replacement without altering your existing machinery.
