About the Airtac SAID200 Double Rod Cylinder SAID200AX105
The AirTAC SAID200X105 is a double-acting, double-rod ISO 15552 profile cylinder engineered for heavy-duty symmetric actuation. 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 SUS420J2 stainless steel rods provide high tensile strength and corrosion resistance, while the extruded aluminum barrel keeps the assembly lightweight despite the massive 200 mm bore.
This through-rod architecture allows you to mount the primary workpiece on the front rod and a position flag or cam on the rear rod for dual-side sensing. It features adjustable air cushioning at both ends to decelerate large masses smoothly, and operates at speeds of 30-500 mm/s. Note that the rear protrusion requires additional clearance in your machine layout compared to a single-rod SAI.

Where the Airtac SAID200 Double Rod Cylinder SAID200AX105 Is Used
Heavy-Duty Pressing
Provides a uniform 15079 N clamping force on both extend and retract strokes, ensuring consistent high-tonnage forming and pressing without force imbalance.
Symmetric Transfer
Drives two synchronized workstations simultaneously from a single piston, using both rod ends to move heavy assemblies in opposite directions with matched speed.
Anti-Rotation Guidance
The twin 40 mm SUS420J2 rods rigidly secure large payloads against torsional deflection, maintaining precise alignment for heavy sliding gantries.
Is the Airtac SAID200 Double Rod Cylinder SAID200AX105 the Right Cylinder?
Select this 200 mm bore cylinder when an application demands immense equal bidirectional force, stepping up from a 160 mm bore (9425 N at 0.5 MPa). The twin-rod design is chosen over a single-rod SAI when the load requires strict anti-rotation guidance or dual-station actuation from one piston. For this 105 mm stroke, the 40 mm rod diameter and M36x2 thread offer excellent side-load capacity, though any external bending moments should still be managed with an external guide rail.
As a dimensionally interchangeable ISO 15552 profile cylinder, it serves as a drop-in replacement for other standard double-rod units. Specify the PT port thread, your preferred mounting accessory (Basic, FA, LB, TC, FTC, TCM1, or TCM2), and note that this unit lacks a magnet. If the machine must hold position without live air pressure, a plain SAID will drift; you must add an external rod lock or explore the BSAID clamp-lock series instead.

- ✓ 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 SAID200AX105 FAQ
Because the double-rod design equalizes the piston area on both sides, it outputs 15079 N in both extend and retract directions at 0.5 MPa, and 21110 N at 0.7 MPa.
Yes, it is dimensionally interchangeable per ISO 15552. You can use it as a drop-in replacement for other standard profile double-rod cylinders, utilizing the standard Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounting interfaces.
