Airtac SAID200 Double Rod Cylinder SAID200BX900
The AirTAC Airtac SAID200 Double Rod Cylinder SAID200BX900 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 900mm stroke, G3/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAID200 Double Rod Cylinder SAID200BX900
The AirTAC SAID200X900 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 900 mm stroke and a 200 mm bore. Because a stainless SUS304 rod exits both end covers, the annulus area is identical on extend and retract. This yields perfectly balanced thrust, generating 15079 N of force in both directions at 0.5 MPa and up to 27141 N at 0.9 MPa.
The twin-rod architecture allows you to mount the primary workpiece on one end while attaching a position flag, cam, or secondary mechanism on the opposite rear rod. An extruded aluminum barrel incorporates sensor grooves on both sides for flexible mounting. Note that the through-rod design requires extra rear clearance and, lacking a lock, the piston will drift if air pressure is lost.

Where the Airtac SAID200 Double Rod Cylinder SAID200BX900 Is Used
Symmetric Force Pressing
Ideal for heavy-duty pressing operations requiring identical 15079 N push and pull forces at 0.5 MPa to maintain balanced load distribution.
Anti-Rotation Slides
The dual SUS304 rods provide exceptional resistance to torsional twisting, guiding heavy industrial slides and lifting platforms without rotational drift.
Twin-Station Actuation
Drive a primary workpiece on the front rod while simultaneously operating a secondary mechanism or position flag from the rear rod end.
Is the Airtac SAID200 Double Rod Cylinder SAID200BX900 the Right Cylinder?
Select this 200 mm bore model when an application demands substantial equal bidirectional force, as opposed to the 160 mm neighbor which provides 9425 N each way at 0.5 MPa. The double-rod design is chosen over a single-rod SAI when superior anti-rotation guidance or dual-side actuation is required. At a 900 mm stroke, the unsupported rod length is highly susceptible to bending under side loads; utilizing an external guide rail is strongly recommended to prevent premature rod-bearing wear.
This cylinder is dimensionally interchangeable per ISO 15552 and uses a PT G3/4 port. It supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). Operating speed is 30-500 mm/s. Remember that standard adjustable air cushions only decelerate the piston near stroke end; to hold a load without live pressure, consider an SAIL or BSAID variant.
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 SAID200BX900 FAQ
Because the double-rod design subtracts rod area from both sides, it delivers equal force in both directions. It outputs 15079 N at 0.5 MPa, 21110 N at 0.7 MPa, and 27141 N at 0.9 MPa.
Yes, the SAID200X900 is dimensionally interchangeable with other ISO 15552 profile cylinders. It uses standard mounting dimensions and a PT G3/4 port, though it requires additional rear clearance for the protruding rod.
