This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200X1200TCN, 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 SI200X1200TCN
The AirTAC SI200 Standard Cylinder SI200X1200TCN is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 1200mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200X1200TCN, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200X1200TCN
The AirTAC SI200X1200TCN is a discontinued double-acting ISO 15552 profile cylinder with a 200 mm bore and 1200 mm stroke. It delivers 15708 N push force at 0.5 MPa via a G3/4 port. The direct replacement is the SAI200X1200TCN, which shares the exact ISO 15552 mounting interface, TC trunnion mount, stroke and force ratings.
This SAI upgrade features a new piston seal with two Y-shaped one-way elements for low start-up pressure and long life. The SAI family also adds SAIL, SAIF and BSAI lock variants the SI lacked. Note this SKU lacks a magnet, so it cannot accept CS1-B/DS1-B sensors.

Where the Airtac SI200 Standard Cylinder SI200X1200TCN Is Used
Heavy Stamp Pressing
Drives large stamping dies requiring 21991 N push at 0.7 MPa, utilizing the 200 mm bore for massive forming force.
Pallet Lifting Stations
Raises 801 kg loads vertically over 1200 mm, relying on external guides to prevent rod bending during transit.
Bulk Material Diversion
Actuates heavy-duty diverter arms on aggregate lines, benefiting from the 50 mm adjustable air cushions to stop smoothly.
Replacing the Airtac SI200 Standard Cylinder SI200X1200TCN with the SAI200X1200TCN
To replace the SI200X1200TCN, order the SAI200X1200TCN. Verify the ISO 15552 TC trunnion interface, 200 mm bore, 1200 mm stroke, G3/4 port and NBR seals. Sizing down, a 160 mm bore yields 10053 N push at 0.5 MPa; sizing up is not available. At 1200 mm stroke, use external guides to prevent rod bending and side loads. This plain cylinder drifts on air loss; for load holding use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant. The cushion only decelerates. As a no-magnet SKU, it cannot take sensors.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200X1200TCN
- ✓ 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 SI200X1200TCN FAQ
Yes, the SI200X1200TCN is discontinued. The direct replacement is the SAI200X1200TCN. It is dimensionally interchangeable per ISO 15552, retaining the same 200 mm bore, 1200 mm stroke, G3/4 port, TC trunnion mount and force ratings.
It features a G3/4 port and delivers 15708 N push / 15080 N pull at 0.5 MPa, 21991 N push at 0.7 MPa, and a theoretical max of 3204 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa with a 50 mm adjustable cushion.
