This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200X200SLB, 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 SI200X200SLB
The AirTAC SI200 Standard Cylinder SI200X200SLB is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 200mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200X200SLB, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200X200SLB
The AirTAC SI200X200SLB is a discontinued double-acting ISO 15552 profile cylinder with a 200mm bore and 200mm stroke, delivering 15708 N push force at 0.5 MPa through its G3/4 port. It is replaced by the direct replacement SAI200X200SLB, which shares the exact same ISO 15552 mounting interface, M36x2 rod thread, and LB foot mount dimensions.
The SAI upgrade features an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and long life. The SAI family also adds SAIL and BSAI lock variants the SI lacked. Your -S magnet works with legacy CS1-B/DS1-B sensors.

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 SAI200X200SLB 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 SI200X200SLB Is Used
Heavy Press Stamping
Drives large press dies requiring 15708 N at 0.5 MPa, utilizing the 200mm stroke for deep metal forming operations.
Mold Clamping Fixtures
Secures heavy industrial molds via the G3/4 port delivering high volume, with CS1-B sensors confirming clamp position.
Replacing the Airtac SI200 Standard Cylinder SI200X200SLB with the SAI200X200SLB
To replace this SI200X200SLB with the SAI200X200SLB, verify the ISO 15552 LB foot mount, 200mm stroke, G3/4 port, and -S magnet for CS1-B/DS1-B switches. Sizing both ways: this 200mm bore gives 15708 N push at 0.5 MPa; dropping to a 160mm bore yields 10053 N. For higher force, 1.0 MPa provides 3204 kgf max. Note that a plain cylinder drifts on air loss—the cushion only decelerates. For load holding, use an external pilot check valve or the SAIL/BSAI lock variant. At 200mm stroke side-load is minimal, but always guide the rod to prevent bending.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200X200SLB
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
