This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200AX105, 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 SI200AX105
The AirTAC SI200 Standard Cylinder SI200AX105 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 105mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200AX105, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200AX105
The AirTAC SI200AX105 is a discontinued double-acting ISO 15552 profile cylinder featuring a 200mm bore and 105mm stroke. Built with an extruded aluminum barrel and a SUS420J2 stainless piston rod, it delivers 15708 N of push force at 0.5 MPa. AirTAC replaced this legacy unit with the SAI200AX105. This current-production direct maintains the exact ISO 15552 mounting interface, bore, stroke, output force, G3/4 port, and M36x2 rod thread, fitting existing fixtures seamlessly.
The SAI upgrade introduces an upgraded piston seal utilizing two Y-shaped one-way elements for low start-up pressure and extended life. Because this specific SI SKU lacks a magnet (-S), it cannot accept position sensors. Note that a plain cylinder drifts without live air; the 50 mm adjustable cushions only decelerate near stroke end.

Where the Airtac SI200 Standard Cylinder SI200AX105 Is Used
Heavy Press Forming
Drives large stamping and forming presses requiring up to 3204 kgf theoretical max force at 1.0 MPa, utilizing the SUS420J2 rod for resilience in harsh environments.
Large Gate Actuation
Actuates massive industrial gates or diverter valves where the 50mm adjustable air cushions absorb kinetic energy at the 105mm stroke endpoints.
Replacing the Airtac SI200 Standard Cylinder SI200AX105 with the SAI200AX105
To replace the discontinued SI200AX105, order the SAI200AX105. Confirm the ISO 15552 mounting interface, 200mm bore, 105mm stroke, G3/4 port, and your specific mounting accessory (LB, FA, TC, etc.). This SKU has no magnet, so it cannot support legacy CS1-B/DS1-B sensors; if sensing is required, switch to an SAI variant with the -S suffix. When sizing, a neighboring 160mm bore yields 10053 N push at 0.5 MPa, while the 200mm bore hits 21991 N at 0.7 MPa. Since this plain cylinder does not hold load on air loss, use an external rod lock, pilot check valve, or the SAIL/BSAI lock variants for suspended loads. The SUS420J2 rod offers corrosion resistance over standard carbon steel.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200AX105
- ✓ 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 SI200AX105 FAQ
Yes, the AirTAC SI200AX105 is discontinued. The direct replacement is the SAI200AX105. It features the same ISO 15552 mounting interface, 200mm bore, 105mm stroke, force, and G3/4 port, but adds an upgraded two Y-shaped element piston seal for longer life.
The 200mm bore features a G3/4 air port. At 0.5 MPa it provides 15708 N push and 15080 N pull force. At 0.7 MPa push is 21991 N, at 0.9 MPa it is 28274 N, and the theoretical max is 3204 kgf at 1.0 MPa. Speed range is 30-500 mm/s.
