About the Airtac SAID200 Double Rod Cylinder SAID200BX950
The AirTAC SAID200X950 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 950 mm stroke. Because a SUS304 stainless steel rod exits both end covers, the annulus area is identical on extend and retract. This yields perfectly symmetric thrust, delivering 15079 N each way at 0.5 MPa and 21110 N at 0.7 MPa.
This through-rod design lets you mount the primary workpiece on one end while attaching a position flag, cam, or secondary mechanism to the rear. The extruded aluminum barrel includes sensor grooves on both sides. Note that this 950 mm stroke is a non-standard made-to-order length exceeding the 1500 mm standard maximum, requiring extra rear-rod clearance.

Where the Airtac SAID200 Double Rod Cylinder SAID200BX950 Is Used
Symmetric Press Drive
Drives a heavy stamping press where equal 15079 N extend and retract forces at 0.5 MPa prevent directional drift during high-tonnage forming operations.
Dual-Station Transfer
Moves parts across two parallel machining stations simultaneously, using the through-rod to actuate a secondary mechanism on the rear side.
Anti-Rotation Guiding
Handles large structural components by utilizing the twin rods to resist twist and maintain precise angular orientation over the 950 mm travel.
Is the Airtac SAID200 Double Rod Cylinder SAID200BX950 the Right Cylinder?
Choose this 200 mm bore when you need massive bidirectional force that a single-rod SAI cannot symmetrically provide. If your application requires less force, stepping down to the 160 mm bore yields 9425 N each way at 0.5 MPa. Because the 950 mm stroke is non-standard, expect a longer overall length and ensure your layout accommodates the rear rod protruding from the back cover.
At 950 mm, the unsupported stroke length is highly susceptible to rod-bearing bending and side loads; always use an external guide to prevent premature wear. This cylinder uses PT tapered ports sized G3/4 and supports mountings Basic, FA, LB, TC, FTC, TCM1, TCM2 (omitting FB/CA/CB/CR). It is dimensionally interchangeable with other ISO 15552 double-rod cylinders. Without a magnet, it cannot host CMSE or DMSE sensors; for position holding without live pressure, consider SAIL or BSAID variants.

- ✓ 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 SAID200BX950 FAQ
Because the double-rod design equalizes the piston area on both sides, the output 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 SAID200X950 shares the ISO 15552 mounting interface and is dimensionally interchangeable with other ISO 15552 double-rod profile cylinders, making it a drop-in replacement for matching footprints.
