About the Airtac SAID200 Double Rod Cylinder SAID200X175S
The AirTAC SAID200X175-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 200 mm bore and 175 mm stroke. Because the twin rods occupy both sides of the piston, the annulus area is identical in each direction, yielding an equal push and pull force of 15079 N at 0.5 MPa (up to 27141 N at 0.9 MPa). The extruded aluminum barrel includes sensor grooves on both sides, and the included -S magnet enables precise end-of-stroke detection with CMSE reed or DMSE electronic switches.
This through-rod design allows a workpiece to mount on one end while a cam, position flag, or secondary mechanism drives from the rear rod, providing superior anti-rotation guidance for heavy loads. Equipped with standard carbon steel rods, PT tapered G3/4 ports, and adjustable air cushions at both ends (50 mm cushion stroke), it offers a dimensionally interchangeable direct replacement for other ISO 15552 double-rod cylinders.

Theoretical Output Force (Ø200mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 15080 N | 15080 N |
| 0.7 MPa | 21111 N | — |

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 SAID200X175S Is Used
Heavy-Duty Symmetric Pressing
Utilizes the equal 15079 N both-way force to drive heavy stamping or forming tools with consistent pressure on both extend and retract strokes.
Dual-Side Transfer Mechanism
Mounts the primary workpiece on the front rod and a synchronized secondary cam or linkage on the rear rod to operate twin stations simultaneously.
Anti-Rotation Guiding
Leverages the twin through-rod structure to prevent torsional deflection when moving heavy, off-center loads in large material handling systems.
Is the Airtac SAID200 Double Rod Cylinder SAID200X175S the Right Cylinder?
Select this 200 mm bore model when an application demands massive bidirectional force (15079 N at 0.5 MPa) alongside strict rotational stability. If the full 27141 N both-way output at 0.9 MPa exceeds your requirement, stepping down to the 160 mm bore yields 9425 N at 0.5 MPa. Choose the SAID twin-rod architecture over a single-rod SAI when you need to drive a secondary mechanism from the rear or require equal speed and force on extend and retract. Note that the SAID mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR variants found on single-rod counterparts.
Although the 175 mm stroke is under the 300 mm threshold, the substantial 40 mm rod diameter and heavy mass of the 200 bore mean external guidance is recommended for optimal bearing life. Remember that a plain SAID does not hold its load if air pressure drops; the air cushions only decelerate the piston near stroke end and do not act as a lock. For position holding without live pressure, consider an external pilot-operated check valve, the SAIL lock variant, or the BSAID clamp-lock 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 SAID200X175S FAQ
Because it is a double-rod cylinder, the force is identical in both directions. It provides 15079 N at 0.5 MPa, 21110 N at 0.7 MPa, and 27141 N at 0.9 MPa.
Yes, the SAID200X175-S is dimensionally interchangeable per ISO 15552 profile cylinder standards, serving as a direct replacement for equivalent double-rod cylinders, featuring a G3/4 PT port and a 40 mm rod.
