About the Airtac SAID200 Double Rod Cylinder SAID200X50
The AirTAC SAID200X50 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 200 mm bore and 50 mm stroke. Because a carbon steel 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. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting.
This through-rod design allows you to mount the primary workpiece on one end and a position flag or secondary cam on the rear. Fluid filtered to 40 um and operating pressures of 0.15-1.0 MPa are supported. It uses adjustable air cushions at both ends to decelerate the piston near stroke limits.

Theoretical Output Force (Ø200mm)
| Pressure | Push force | Pull force |

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 SAID200X50 Is Used
Twin-Station Press
Drives a heavy stamping die on the front rod while synchronizing a secondary ejection mechanism on the rear rod for high-force metal forming.
Anti-Rotation Guide
Lifts and lowers heavy platens with absolute stability, using the double-rod geometry to prevent mechanical binding and torsional drift.
Symmetric Force Transfer
Alternates heavy workpiece pallets back and forth, leveraging the exact 15079 N of equal push and pull force to maintain consistent cycle timing.
Is the Airtac SAID200 Double Rod Cylinder SAID200X50 the Right Cylinder?
Choose this 200 mm bore when an application requires massive symmetric thrust, as it generates 15079 N in both directions at 0.5 MPa. If you need less force, stepping down to the 160 mm bore yields 9425 N each way. The twin-rod architecture is selected over a single-rod SAI when precise anti-rotation guidance or dual-side actuation is required. Remember that adjustable cushions only decelerate the piston; they do not hold a load. If position holding without air pressure is needed, use an external rod lock or a BSAID clamp-lock cylinder.
This model features PT tapered ports sized at G3/4 and standard carbon steel rods. It is dimensionally interchangeable per ISO 15552 for direct replacement of other double-rod profile cylinders. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAID200X50 FAQ
Because the rod occupies both sides of the piston, the effective area is identical in both directions. It provides 15079 N of force at 0.5 MPa, 21110 N at 0.7 MPa, and 27141 N at 0.9 MPa on both extend and retract strokes.
Yes, the SAID200X50 is dimensionally interchangeable per ISO 15552. It serves as a direct replacement for other ISO 15552 double-rod profile cylinders, utilizing a standard G3/4 PT port and a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2).
