This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100BX200, 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 SI100 Standard Cylinder SI100BX200
The AirTAC Airtac SI100 Standard Cylinder SI100BX200 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 200mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100BX200, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100BX200
The AirTAC SI100BX200 is a discontinued double-acting ISO 15552 profile cylinder with a 100mm bore and 200mm stroke. It delivers 3927N push force at 0.5MPa and features a SUS304 stainless steel rod, a G1/2 port, and 36mm adjustable cushions. The direct replacement is the SAI100BX200, which shares identical ISO 15552 mounting dimensions, force, and porting.
The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and long life. Note that this no-magnet SKU cannot accept a sensor, and plain cylinders drift without air; explore SAIL or BSAI lock variants if load holding is required.

Where the Airtac SI100 Standard Cylinder SI100BX200 Is Used
Heavy-Duty Pressing
Drives robust pressing and stamping tasks requiring up to 5497N of thrust at 0.7MPa, utilizing the durable SUS304 rod for corrosion resistance.
Material Lift Stations
Raises and lowers bulky fixtures in automated warehouses, relying on the 36mm adjustable cushions to smoothly decelerate 100mm bore loads.
Replacing the Airtac SI100 Standard Cylinder SI100BX200 with the SAI100BX200
To replace the SI100BX200, order the SAI100BX200. Confirm the ISO 15552 mounting interface, the 100mm bore, 200mm stroke, G1/2 port (PT/G/NPT thread options), and your specific mounting accessory. Because this SKU lacks an -S magnet, it cannot support legacy CS1-B/DS1-B sensors; order a magnet-equipped version if position sensing is needed. Sizing both ways: a neighbouring 80mm bore yields 2513N push at 0.5MPa, while a 125mm bore yields 6136N. The SAI family also adds SAIF (integrated valve) and SAIL/BSAI lock variants. For any load holding, note the air cushion only decelerates; add an external rod lock or pilot check valve. At 200mm stroke, rod bending is minimal, but always guide the load to prevent side-load wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100BX200
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SI100 Standard Cylinder SI100BX200 FAQ
Yes, the SI100BX200 is discontinued. The direct replacement is the SAI100BX200. It is dimensionally interchangeable per ISO 15552, retaining the same 100mm bore, 200mm stroke, G1/2 port, and mounting interface, but features an upgraded two Y-shaped one-way piston seal for lower start-up pressure.
The 100mm bore features a G1/2 air port and a 25mm rod. It delivers 3927N push and 3681N pull at 0.5MPa, 5497N push at 0.7MPa, 7068N push at 0.9MPa, and a theoretical maximum of 801kgf at 1.0MPa.
