This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100BX700, 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 SI100BX700
The AirTAC Airtac SI100 Standard Cylinder SI100BX700 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 700mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100BX700, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100BX700
The AirTAC SI100BX700 is a discontinued double-acting ISO 15552 profile cylinder with a 100mm bore and 700mm stroke. It delivers 3927N push and 3681N pull at 0.5MPa via a G1/2 port. The direct replacement is the SAI100BX700, retaining identical mounting, force, and stroke.
The SAI upgrade features two Y-shaped one-way piston seals for low start-up pressure and long life. This SKU has a SUS304 stainless rod (-B) but no magnet, so it cannot take CS1-B/DS1-B sensors.

Where the Airtac SI100 Standard Cylinder SI100BX700 Is Used
Heavy Material Transfer
Drives large pallets or heavy fixtures over 700mm on assembly lines, using the 3927N push force at 0.5MPa to shift substantial masses smoothly.
Automated Warehousing
Executes 700mm lifting and pushing motions in high-bay storage systems, where the SUS304 rod resists environmental moisture and corrosion.
Large Press Feeding
Feeds heavy blanks into forming presses, relying on adjustable end cushions to decelerate the 100mm bore payload over the extended stroke.
Replacing the Airtac SI100 Standard Cylinder SI100BX700 with the SAI100BX700
To replace the SI100BX700, order the SAI100BX700. Verify the ISO 15552 interface, 700mm stroke, G1/2 port, and M20x1.5 rod thread. Neighbouring bores: 80mm yields 2513N [email protected], 125mm yields 6136N. This SKU lacks a magnet (-S), so it cannot accept position sensors. For load holding, note the cushion only decelerates; use an external pilot check valve or SAIL/BSAI lock variant. At 700mm, prevent rod bending by guiding the load externally.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100BX700
- ✓ 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 SI100BX700 FAQ
Yes, the SI100BX700 is discontinued. The direct replacement is the SAI100BX700. It is dimensionally interchangeable per ISO 15552, matching the 100mm bore, 700mm stroke, G1/2 port, and mounting interface. The SAI simply upgrades the piston seal to two Y-shaped elements for lower start-up pressure.
The G1/2 port is fixed by the 100mm bore. It produces 3927N push and 3681N pull at 0.5MPa, 5497N push at 0.7MPa, 7068N at 0.9MPa, and a theoretical max of 801kgf at 1.0MPa. Speed is 30-800mm/s.
