This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200AX100, 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 SI200AX100
The AirTAC Airtac SI200 Standard Cylinder SI200AX100 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 100mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200AX100, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200AX100
The AirTAC SI200AX200 is a discontinued double-acting ISO 15552 profile cylinder with a 200mm bore and 100mm stroke. Built to deliver 15708 N push force at 0.5 MPa, it features a SUS420J2 stainless piston rod and a G3/4 air port. AirTAC replaced this legacy unit with the SAI200AX100, a direct replacement sharing the exact ISO 15552 mounting interface, bore, stroke, output force, port and mounting fixtures.
The SAI200AX100 upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and extended life. Note this no-magnet SKU cannot take a sensor, and plain cylinders drift without air; for load holding explore the SAIL lock or BSAI clamp-lock variants the SI line lacked.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAI200AX100 carries the same ISO 15552 ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
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 SAI200AX100 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 SI200AX100 Is Used
Heavy Pressing
Drives 15708 N at 0.5 MPa for seating large bearings or forming heavy plate metal in automated lines.
Clamp Fixtures
Secures oversized castings during machining, using the SUS420J2 stainless rod for corrosion resistance.
Replacing the Airtac SI200 Standard Cylinder SI200AX100 with the SAI200AX100
To replace the SI200AX100, order the SAI200AX100. Confirm the ISO 15552 mounting interface, 200mm bore, 100mm stroke, G3/4 port (PT/G/NPT) and mounting accessory match your fixture. This SKU lacks a magnet (-S), so it cannot accept a CS1-B/DS1-B sensor; if position detection is needed, select a magnet-equipped SAI. For sizing, a 160mm bore neighbor offers 10053 N push at 0.5 MPa, while stepping up to the 200mm bore here provides 15708 N. Remember the air cushion only decelerates; it does not hold load. For static holding on air loss, specify an external rod lock, pilot check valve, or the SAIL/BSAI lock variants. Stroke is under 300mm so rod-bending side-load risks are minimal, but always guide the load.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200AX100
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
