This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200AX175S, 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 SI200AX175S
The AirTAC SI200 Standard Cylinder SI200AX175S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 175mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200AX175S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200AX175S
The AirTAC SI200AX175S is a discontinued double-acting ISO 15552 profile cylinder with a 200mm bore and 175mm stroke. Built for heavy thrust, it delivers 15708 N push and 15080 N pull at 0.5 MPa through a G3/4 port. The direct replacement is the SAI200AX175S, which retains the identical ISO 15552 mounting interface, stroke, force, and porting for seamless fixture integration.
This specific unit features a SUS420J2 stainless piston rod and a built-in magnet for CS1-B/DS1-B sensors. The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and long life. Note that standard cylinders drift without live air; for load holding, explore the SAIL or BSAI lock variants.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAI200AX175S 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 SAI200AX175S 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 SI200AX175S Is Used
Heavy Press Operations
Drives large stamping and forming presses requiring up to 21991 N of thrust at 0.7 MPa, utilizing the 175mm stroke for deep draw operations.
Industrial Clamp Systems
Secures massive fabricated steel components during welding or machining, providing 15080 N of pull force to hold heavy jigs firmly in place.
Replacing the Airtac SI200 Standard Cylinder SI200AX175S with the SAI200AX175S
To replace the SI200AX175S, order the SAI200AX175S. Confirm the ISO 15552 mounting interface, the 175mm stroke, the G3/4 port, and the -S magnet for legacy CS1-B/DS1-B switches (the SAI uses current AirTAC switches). The -A rod denotes SUS420J2 stainless steel. Sizing both ways: this 200mm bore yields 15708 N at 0.5 MPa; if you need less force, a 160mm bore offers 10053 N. For load holding on air loss, a plain cylinder drifts because the cushion only decelerates—use an external pilot check valve or the SAIL/BSAI lock variants. Since 175mm is under 300mm, side-load rod bending is minimal, but always verify guide alignment.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200AX175S
- ✓ 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 SI200AX175S FAQ
Yes, the SI200AX175S is discontinued. The direct replacement is the SAI200AX175S. It is dimensionally interchangeable per ISO 15552, maintaining the same 200mm bore, 175mm stroke, force, G3/4 port, and mounting interface, but features an upgraded two Y-shaped one-way piston seal.
This 200mm bore cylinder has a G3/4 air port. The thrust ratings are 15708 N push and 15080 N pull at 0.5 MPa, 21991 N push at 0.7 MPa, 28274 N push at 0.9 MPa, and a theoretical maximum force of 3204 kgf at 1.0 MPa.
