This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200X600TC, 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 SI200X600TC
The AirTAC SI200 Standard Cylinder SI200X600TC is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 600mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200X600TC, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200X600TC
The AirTAC SI200X600TC is a discontinued double-acting ISO 15552 profile cylinder with a 200mm bore and 600mm stroke. Delivering 15708 N of push force at 0.5 MPa via a G3/4 port, it is replaced by the SAI200X600TC. This direct successor matches the exact ISO 15552 mounting interface, bore, stroke, force, and TC trunnion mount.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. It also introduces SAIL, SAIF, and BSAI lock variants the SI lacked. Note this non-S SKU lacks a magnet and cannot take a sensor.

Where the Airtac SI200 Standard Cylinder SI200X600TC Is Used
Heavy Press Forming
Drives large stamping presses with 21991 N of push force at 0.7 MPa, utilizing the TC trunnion mount to accommodate articulation.
Automated Assembly Platen
Shifts massive industrial platens across the 600mm travel, relying on external guides to prevent rod bending.
Replacing the Airtac SI200 Standard Cylinder SI200X600TC with the SAI200X600TC
To replace the SI200X600TC, order the SAI200X600TC. Verify the ISO 15552 TC trunnion interface, 200mm bore, 600mm stroke, and G3/4 port. Because this is a non-S model, it cannot accept CS1-B or DS1-B sensors. If sizing down, a 160mm bore yields 10053 N push at 0.5 MPa; sizing up is not available. For this 600mm stroke, use an external guide to prevent rod bending and side-load wear. A plain cylinder drifts on air loss; for load holding, use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200X600TC
- ✓ 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 SI200X600TC FAQ
Yes, the SI200X600TC is discontinued. The direct replacement is the SAI200X600TC. It shares the identical ISO 15552 mounting interface, 200mm bore, 600mm stroke, output force, G3/4 port, and TC trunnion mount, fitting directly into existing fixtures.
This double-acting cylinder features a G3/4 port. It delivers 15708 N push and 15080 N pull at 0.5 MPa, 21991 N push at 0.7 MPa, and 28274 N push at 0.9 MPa. The theoretical maximum force is 3204 kgf at 1.0 MPa. Operating speed is 30-500 mm/s.
