This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200AX5, 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 SI200AX5
The AirTAC Airtac SI200 Standard Cylinder SI200AX5 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 5mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200AX5, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200AX5
The AirTAC SI200AX5 is a discontinued double-acting ISO 15552 profile cylinder with a 200 mm bore and 5 mm stroke. It delivers 15708 N push force at 0.5 MPa and uses a G3/4 port. The direct replacement is the SAI200AX5, matching the exact interface, force, and mounting. This specific SKU features a SUS420J2 stainless steel rod (A suffix) but lacks a magnet, meaning it cannot accept position sensors.
The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and long life. The SAI family also adds SAIL and BSAI lock variants absent in the SI line.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAI200AX5 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 |

Where the Airtac SI200 Standard Cylinder SI200AX5 Is Used
Heavy-Duty Pressing
Applies 15708 N at 0.5 MPa for short-stroke stamping, riveting, and seating heavy industrial components.
High-Force Clamping
Generates massive holding power for securing large steel fabrications during machining or welding processes.
Replacing the Airtac SI200 Standard Cylinder SI200AX5 with the SAI200AX5
To replace the SI200AX5, order the SAI200AX5. Confirm the ISO 15552 mounting interface, 200 mm bore, 5 mm stroke, G3/4 port, and SUS420J2 rod. Because this SKU lacks the -S magnet, it cannot support CS1-B/DS1-B sensors; order a magnet-equipped SAI if sensing is needed. Sizing downward, a 160 mm bore offers 10053 N push at 0.5 MPa; sizing upward is not available. A plain cylinder drifts on air loss, so for load holding use an external pilot check valve or the SAIL/BSAI lock variant. Even at 5 mm stroke, verify guide alignment to prevent rod bending.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200AX5
- ✓ 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 SI200AX5 FAQ
Yes, the SI200AX5 is discontinued. The direct replacement is the SAI200AX5. It is dimensionally interchangeable per ISO 15552, retaining the same 200 mm bore, 5 mm stroke, force, G3/4 port, and mounting interface.
It features a G3/4 port. The force 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 max of 3204 kgf at 1.0 MPa.
