About the Airtac SAID200 Double Rod Cylinder SAID200X175
The AirTAC SAID200X175 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 200mm bore and 175mm stroke. Because a carbon steel rod extends from both end covers, the effective annulus area is identical on both sides, yielding exactly 15079 N of thrust and pull force at 0.5 MPa in either direction.
This through-rod architecture allows mounting a primary workpiece on one end while utilizing the rear extension for a cam, position flag, or secondary mechanism. The extruded aluminum barrel includes sensor grooves on both sides, and the adjustable air cushions at both ends provide 50 mm of deceleration travel to absorb heavy kinetic energy.

Theoretical Output Force (Ø200mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 15080 N | 15080 N |
| 0.7 MPa | 21111 N | — |
| Max (@1.0 MPa) | 3075 kgf | |
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 SAID200X175 Is Used
Anti-Rotation Slides
The twin through-rods provide superior torsional resistance, keeping heavy 200mm bore loads perfectly aligned without rotational drift during transfer.
Symmetric-Force Transfer
Delivers an identical 15079 N push and pull force at 0.5 MPa, ensuring perfectly balanced kinetic energy for heavy pressing and forming operations.
Rear-Mounted Cams
The protruding rear rod end acts as a stable mounting platform for mechanical cams or position flags to trigger external sequence valves.
Is the Airtac SAID200 Double Rod Cylinder SAID200X175 the Right Cylinder?
Select this 200mm bore model when an application demands massive bidirectional force matching exactly 21110 N at 0.7 MPa, stepping up from the 160mm bore which provides 13194 N at the same pressure. The twin-rod design is chosen over a single-rod SAI when strict anti-rotation guidance or dual-side actuation is required. Note that a plain SAID cylinder does not hold its load if air pressure is lost; for fail-safe holding, consider an external rod lock or the BSAID clamp-lock variant.
As a dimensionally interchangeable ISO 15552 cylinder, it supports PT threaded G3/4 ports and a reduced mounting accessory set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting the FB, CA, CB, and CR brackets found on single-rod variants. Although 175mm is a standard stroke, the heavy 40mm rod and large piston mass mean external guides are recommended to manage side-load bending on the rod bearing.
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 SAID200X175 FAQ
Because the double-rod design creates equal annulus areas on both sides, the SAID200X175 outputs 15079 N at 0.5 MPa, 21110 N at 0.7 MPa, and 27141 N at 0.9 MPa in both the extend and retract directions.
Yes, it is dimensionally interchangeable per ISO 15552, but the double-rod design uses a reduced mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2. It omits the FB, CA, CB, and CR brackets used on single-rod cylinders.
