This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160BX950, 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 SI160 Standard Cylinder SI160BX950
The AirTAC Airtac SI160 Standard Cylinder SI160BX950 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 950mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160BX950, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160BX950
The AirTAC SI160BX950 is a discontinued double-acting ISO 15552 profile cylinder with a 160mm bore and 950mm stroke. Delivering 10053N push force at 0.5MPa, it features a SUS304 stainless piston rod for corrosion resistance. The direct replacement is the SAI160BX950, retaining the same G3/4 port, M36x2 thread, and ISO 15552 mounting interface.
The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and long life. Note this SKU lacks a magnet and cannot take a sensor.

Where the Airtac SI160 Standard Cylinder SI160BX950 Is Used
Heavy Pressing
Drives large stamping and forming presses requiring 10053N push force at 0.5MPa with a robust 160mm bore.
Material Handling
Shifts heavy industrial loads on production lines, relying on the SUS304 stainless rod for harsh environments.
Replacing the Airtac SI160 Standard Cylinder SI160BX950 with the SAI160BX950
To replace this SI160BX950, order the SAI160BX950, confirming the ISO 15552 interface, 160mm bore, 950mm stroke, G3/4 port, and SUS304 rod. Neighbouring bore options are 125mm (6136N @0.5MPa) or 200mm (15708N). Because this is a 950mm stroke, use external guides to prevent rod bending and side-load wear. A plain cylinder drifts on air loss; for load holding use an external pilot check valve or the SAIL/BSAI lock variants. The cushion only decelerates.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160BX950
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SI160 Standard Cylinder SI160BX950 FAQ
Yes, the SI160BX950 is discontinued. The direct replacement is the SAI160BX950. It is dimensionally interchangeable per ISO 15552, keeping the same 160mm bore, 950mm stroke, force, G3/4 port, and mounting.
The G3/4 port bore delivers push 10053N and pull 9425N at 0.5MPa, push 14074N at 0.7MPa, push 18095N at 0.9MPa, and a max force of 2050kgf at 1.0MPa. Speed is 30-500mm/s.
