This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200X310CB, 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 SI200 Standard Cylinder SI200X310CB
The AirTAC Airtac SI200 Standard Cylinder SI200X310CB is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 310mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200X310CB, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200X310CB
The AirTAC SI200X310CB is a discontinued double-acting ISO 15552 profile cylinder with a 200mm bore and 310mm stroke. Delivering 15708 N push and 15080 N pull at 0.5 MPa, it is replaced direct by the SAI200X310CB. This successor shares the exact CB clevis mount, G3/4 port, and M36x2 rod thread, fitting existing fixtures perfectly.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. For load holding, note that air cushions only decelerate; use an external rod lock or SAIL/BSAI variant to prevent drift. Without a -S magnet, this SKU cannot take a sensor.

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 SAI200X310CB produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac SI200 Standard Cylinder SI200X310CB Is Used
Heavy Press Forming
Applies up to 21991 N at 0.7 MPa for stamping and forming dense materials, utilizing the 310mm stroke to clear large workpieces.
Pallet Lift Stations
Drives heavy vertical lifting platforms.
Automated Clamp Systems
Secures large fabricated components during machining using the robust CB clevis mount to handle high reaction forces.
Replacing the Airtac SI200 Standard Cylinder SI200X310CB with the SAI200X310CB
To replace the SI200X310CB, order the SAI200X310CB. Verify the ISO 15552 CB clevis mount, 310mm stroke, G3/4 port, and M36x2 thread. Since this SKU lacks the -S magnet, it cannot accept CS1-B/DS1-B sensors; order a magnet-equipped SAI if position detection is needed. Sizing both ways: the 160mm bore neighbor yields 10053 N [email protected], while this 200mm bore hits 21991 N at 0.7 MPa. For the 310mm stroke, use external guides to prevent rod bending under side loads. Because cushions only decelerate, add a pilot check valve or SAIL lock to hold loads safely.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200X310CB
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SI200 Standard Cylinder SI200X310CB FAQ
Yes, the SI200X310CB is discontinued. The direct replacement is the SAI200X310CB. It is dimensionally interchangeable per ISO 15552, retaining the same 200mm bore, 310mm stroke, CB clevis mount, and G3/4 port. The SAI features an upgraded piston seal for longer life.
The 200mm bore uses a G3/4 port. Force output is 15708 N push and 15080 N pull at 0.5 MPa, 21991 N push at 0.7 MPa, 28274 N at 0.9 MPa, and a theoretical max of 3204 kgf at 1.0 MPa. Speed is 30-500 mm/s.
