About the Airtac SAID200 Double Rod Cylinder SAID200BX950S
The AirTAC SAID200X950-S is a double-acting, double-rod ISO 15552 profile cylinder engineered for heavy-duty symmetrical actuation. By routing a SUS304 stainless steel rod through both end covers, it provides an equal effective area on both sides of the piston. This yields a consistent push and pull force of 15079 N at 0.5 MPa, preventing the speed and force disparity found in single-rod units.
Equipped with a -S magnet, this model supports CMSE reed and DMSE electronic sensors via dual-side grooves on the extruded aluminum barrel. The 950 mm stroke is a non-standard made-to-order length exceeding the 1500 mm standard maximum, requiring extra rear-rod clearance. It features PT tapered ports (G3/4) and adjustable air cushions at both ends to decelerate the massive load smoothly.

Where the Airtac SAID200 Double Rod Cylinder SAID200BX950S Is Used
Anti-Rotation Slides
The dual SUS304 rods provide rigid guidance against torsion, keeping heavy workpieces perfectly aligned without twisting during transfer.
Symmetric Force Transfer
Ideal for pressing and forming tasks requiring identical 15079 N force in both directions, eliminating the need for pressure compensation.
Through-Rod Sensing
Mount a position flag or cam on the rear rod end to trigger CMSE or DMSE sensors, tracking the opposite side of the mechanism.
Is the Airtac SAID200 Double Rod Cylinder SAID200BX950S the Right Cylinder?
Choose this 200 mm bore cylinder when an application demands immense bidirectional force and strict anti-rotation guidance. If you need less force, stepping down to a 160 mm bore yields 9425 N at 0.5 MPa. The twin SUS304 rods supply superior side-load resistance compared to a single-rod SAI, but at 950 mm of travel, an external guide is still required to prevent rod-bearing bending. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, CR). This unit is dimensionally interchangeable per ISO 15552. Remember that the air cushion only decelerates the piston; it does not hold the load when air is lost. For position holding, use a SAIL lock, BSAID clamp-lock, or external rod lock.
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 SAID200BX950S FAQ
Because the rod occupies both sides of the piston, the effective area is identical in both directions. It delivers 15079 N of force at 0.5 MPa, 21110 N at 0.7 MPa, and 27141 N at 0.9 MPa for both extension and retraction.
Yes, the SAID200X950-S is dimensionally interchangeable per ISO 15552. You can use it as a drop-in replacement for other ISO 15552 double-rod profile cylinders, maintaining the same mounting footprint and G3/4 PT port locations.
