About the Airtac SAID200 Double Rod Cylinder SAID200X450
The AirTAC SAID200X450 is a double-acting, double-rod ISO 15552 profile cylinder engineered for heavy-duty symmetric actuation. Because a 40 mm carbon steel rod exits both end covers, the effective piston area is identical on extend and retract. This means you get exactly 15079 N of force in both directions at 0.5 MPa, eliminating speed and force mismatch. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic switches.
Designed with a 450 mm stroke and a G3/4 PT tapered port, this massive unit operates at speeds of 30-500 mm/s. The twin-rod architecture provides superior anti-rotation guidance and allows you to drive a primary workpiece from one end while mounting a cam or position flag on the rear rod. Adjustable air cushions at both ends absorb kinetic energy, but note this cylinder is not a locking device and will drift if air pressure is lost.

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 SAID200X450 Is Used
Symmetric Press Drive
Provides 15079 N of equal force on both extend and retract strokes, ideal for heavy presses that require balanced clamping and release forces without speed variation.
Twin-Station Transfer
Uses the through-rod design to actuate a primary workpiece on the front stroke while driving a secondary cam or limit flag on the rear, synchronizing dual mechanisms.
Anti-Rotation Guide
Leverages the double-ended 40 mm rod architecture to maintain strict linear guidance and prevent torsional rotation on heavy lifting slides.
Is the Airtac SAID200 Double Rod Cylinder SAID200X450 the Right Cylinder?
Selecting the SAID200X450 is ideal when an application demands immense bidirectional force and high torsional stability. If you need slightly less thrust, stepping down to the 160 mm bore yields 9425 N both ways at 0.5 MPa. Conversely, if you require even higher forces, there is no larger standard SAID bore. You would choose this double-rod variant over a single-rod SAI when you need equal extend/retract speeds, dual-side guidance to prevent load rotation, or rear-rod actuation for a secondary mechanism.
As a genuine ISO 15552 profile cylinder, it is dimensionally interchangeable with other ISO 15552 double-rod cylinders, utilizing a standard 200 mm bore and 450 mm stroke. It supports a mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). Because this model lacks the -S magnet, it cannot host internal sensors. At 450 mm stroke, the long 40 mm rod can generate significant bending moments under side loads—always use an external guide rail to protect the rod bearing. For applications needing true load holding without live pressure, consider the SAIL or BSAID series instead.

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 SAID200X450 FAQ
Because the double-rod design creates equal annulus areas on both sides, the output force is identical in both directions. It delivers 15079 N at 0.5 MPa, 21110 N at 0.7 MPa, and 27141 N at 0.9 MPa.
Yes. It is a true ISO 15552 profile cylinder, making its mounting interface dimensionally interchangeable with other ISO 15552 double-rod cylinders. It uses a G3/4 PT port and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts.
