About the Airtac SAID200 Double Rod Cylinder SAID200X300
The AirTAC SAID200X300 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 200 mm bore and 300 mm stroke. Because a rod exits both ends, the annulus area is identical on extend and retract, yielding exactly 15079 N of force in each direction at 0.5 MPa. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed and DMSE electronic switches.
This twin-rod configuration is purpose-built for applications requiring dual-side guidance and anti-rotation stability. You can mount the primary workpiece on one rod end and attach a cam, position flag, or secondary tool to the rear protruding rod. The carbon steel rod and G3/4 PT tapered ports are engineered to handle heavy loads, though the extended overall length requires additional rear clearance.

Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAID200 Double Rod Cylinder SAID200X300 Is Used
Heavy-Duty Pressing
Provides 15079 N of equal pressing and retraction force at 0.5 MPa, ensuring consistent forming and ejection without asymmetric speed drift.
Symmetric Transfer
Drives a dual-sided transfer carriage where the rear rod simultaneously operates a secondary mechanism, maintaining balanced load distribution.
Anti-Rotation Slides
The twin-rod design prevents mechanical twist on heavy 200 mm bore assemblies, keeping large guided tooling perfectly aligned throughout the 300 mm stroke.
Is the Airtac SAID200 Double Rod Cylinder SAID200X300 the Right Cylinder?
Selecting the SAID200X300 is optimal when your mechanism demands high bidirectional force and strict anti-rotation control that a single-rod SAI cannot provide. If your application needs less force, stepping down to the 160 mm bore yields 9425 N both ways at 0.5 MPa. For this 300 mm stroke, the long unsupported piston rod is susceptible to side-load bending; always use an external guide to prevent rod-bearing damage.
This cylinder is dimensionally interchangeable per ISO 15552, making it a direct replacement for other ISO 15552 double-rod cylinders. It uses the reduced SAID mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR accessories. Note that the adjustable air cushions only decelerate the piston near stroke end; this cylinder does not hold position or lock loads when air is exhausted. For dead-load holding, consider an external rod lock or the SAIL series.

- ✓ 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 SAID200X300 FAQ
Because the double-rod design subtracts the rod area from both sides, the extend and retract forces are equal. It outputs 15079 N both ways at 0.5 MPa, 21110 N at 0.7 MPa, and 27141 N at 0.9 MPa.
Yes, the SAID200X300 is dimensionally interchangeable per ISO 15552 and serves as a direct replacement for other ISO 15552 profile double-rod cylinders. It uses a G3/4 PT port and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts.
