This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200AX190, 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 SI200AX190
The AirTAC Airtac SI200 Standard Cylinder SI200AX190 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 190mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200AX190, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200AX190
The AirTAC SI200AX190 is a discontinued double-acting ISO 15552 profile cylinder with a 200 mm bore and 190 mm stroke. Built with an extruded aluminum barrel and a SUS420J2 stainless piston rod, it delivers 15708 N push force at 0.5 MPa through a G3/4 port. AirTAC replaced this legacy unit with the SAI200AX190, a direct replacement retaining the exact ISO 15552 mounting interface, bore, stroke, output force, and port size.
The SAI upgrade features a modernized piston seal using two Y-shaped one-way elements for low start-up pressure and extended life. Note this specific SKU lacks a magnet and cannot support position sensing.

Where the Airtac SI200 Standard Cylinder SI200AX190 Is Used
Heavy Stamping Press
Drives large heavy-duty stamping dies requiring high thrust, utilizing the 15708 N push force at 0.5 MPa to form thick metal plates.
Industrial Automation Clamp
Secures massive fabricated components during welding or machining, relying on the SUS420J2 stainless rod for corrosion resistance.
Palletizer Actuator
Moves heavy loaded pallets in packaging lines, benefiting from the 50 mm adjustable air cushions to decelerate the 200 mm bore safely.
Replacing the Airtac SI200 Standard Cylinder SI200AX190 with the SAI200AX190
To replace the discontinued SI200AX190, order the SAI200AX190. Verify your existing fixture matches the ISO 15552 mounting interface dimensions, the 190 mm stroke, and the G3/4 port. Because this SKU lacks the -S magnet, it cannot accept legacy CS1-B/DS1-B sensors; if sensing is required, switch to a magnet-equipped SAI variant. When sizing, note the 200 mm bore yields 15708 N push at 0.5 MPa; if you need less force, step down to a 160 mm bore (10053 N push). For load holding, remember a standard cylinder drifts on air loss—the cushion only decelerates. Use an external pilot check valve or explore SAIL/BSAI lock variants for secure holding.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200AX190
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
