This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAID200X900S, with the same bore, stroke, output force, port and mounting, so it fits the same application. The SAI replacement keeps the same ISO 15552 mounting interface, bore, stroke, output force and accessories, so it drops straight into existing fixtures. It is the current-production version of this cylinder with an upgraded piston seal.
Airtac SID Series Double-Rod Cylinder SID200X900S
The AirTAC Airtac SID Series Double-Rod Cylinder SID200X900S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 900mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAID200X900S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SID Series Double-Rod Cylinder SID200X900S
The AirTAC SID200X900S is a discontinued double-acting double-rod ISO 15552 cylinder where a rod exits both ends on one piston, ensuring push and pull force are equal at 15080 N @0.5 MPa, 21110 N @0.7 MPa, and 27141 N @0.9 MPa. The direct replacement is the SAID200X900S, matching the 200mm bore, 900mm stroke, G3/4 port, and mounting interface. The SAI family upgrades the piston seal to two Y-shaped one-way elements for lower start-up pressure and longer life.
With a 40mm rod, M36x2 thread, and 50mm adjustable cushions at each end, this 900mm stroke model requires external guides to prevent rod bending under side loads. The -S suffix denotes a built-in piston magnet for legacy CS1-B/DS1-B switches. A plain cylinder drifts on air loss; cushions only decelerate near stroke end, so use an external rod lock or SAIL/BSAI variant for held loads.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAID200X900S carries the same ISO 15552 ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø200mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 15708 N | 15080 N |
| 0.7 MPa | 21991 N | — |
| Max (@1.0 MPa) | 3204 kgf | |
The SAID200X900S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac SID Series Double-Rod Cylinder SID200X900S Is Used
Equal-Force Transfer Pusher
Drives a conveyor diverter with identical push and pull force of 21110 N @0.7 MPa in both directions, ensuring consistent actuation regardless of travel direction.
Dual-Tool Machining Slide
Uses the rod exiting both ends to drive two separate tools simultaneously from one piston, maintaining equal 15080 N @0.5 MPa force on both strokes.
Replacing the Airtac SID Series Double-Rod Cylinder SID200X900S with the SAID200X900S
To replace the discontinued SID200X900S, specify the SAID200X900S, which provides a direct swap retaining the ISO 15552 mounting interface and G3/4 port. Size both directions by verifying the equal both ways force (15080 N @0.5 MPa) meets your requirement; if lower, the SAID160X900S neighbour bore drops force, while custom larger bores are unavailable in this ISO range. A double rod is right when you need equal force both ways, anti-rotation stability, or a back rod to carry a sensor cam. Mounting options include Basic, FA, LB, and TC (no FB/CA/CB/CR). The -S magnet supports legacy CS1-B/DS1-B sensors. For this 900mm stroke, external guides are mandatory to manage side-load and rod-bending.
Replacement checklist
- ✓ Same ISO 15552 interface → SAID200X900S
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SID Series Double-Rod Cylinder SID200X900S FAQ
Yes, the SID200X900S is discontinued. The direct replacement is the SAID200X900S, which matches the 200mm bore, 900mm stroke, G3/4 port, and ISO 15552 mounting interface, while adding an upgraded piston seal.
Force is equal both ways at 15080 N @0.5 MPa, 21110 N @0.7 MPa, and 27141 N @0.9 MPa. Speed is 30-500 mm/s. It features a 40mm rod, M36x2 thread, and 50mm adjustable cushions.
