This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160BX200S, 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 SI160BX200S
The AirTAC SI160 Standard Cylinder SI160BX200S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 200mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160BX200S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160BX200S
The AirTAC SI160BX200S is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 200 mm stroke. It delivers 10053 N push force at 0.5 MPa and features a SUS304 stainless piston rod, G3/4 port, and a piston magnet for position sensing. The direct replacement is the SAI160BX200S, matching the bore, stroke, force, port, 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. The SAI family also adds SAIL and BSAI lock variants absent from the SI line.

Where the Airtac SI160 Standard Cylinder SI160BX200S Is Used
Heavy Stamping Press
Drives large heavy-duty stamping dies requiring high thrust, utilizing the 10053 N push force at 0.5 MPa with robust ISO 15552 mounting.
Large Clamp Assembly
Secures heavy fabricated steel components during welding or machining using the SUS304 stainless rod for corrosion resistance.
Replacing the Airtac SI160 Standard Cylinder SI160BX200S with the SAI160BX200S
To replace the SI160BX200S, order the SAI160BX200S and confirm the ISO 15552 mounting interface, 200 mm stroke, G3/4 port, and mounting accessory. The -B rod is SUS304 stainless steel and the -S magnet works with legacy CS1-B/DS1-B sensors (the SAI uses current AirTAC switches). Sizing both ways: the neighboring 125 mm bore yields 6136 N push at 0.5 MPa, while this 160 mm bore yields 14074 N at 0.7 MPa. A plain cylinder drifts on air loss as the cushion only decelerates; for load holding use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant. For any stroke over 300 mm, add a guide to prevent rod bending and side-load damage.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160BX200S
- ✓ 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 SI160BX200S FAQ
Yes, the SI160BX200S is discontinued. The direct replacement is the SAI160BX200S. It is dimensionally interchangeable per ISO 15552, keeping the same 160 mm bore, 200 mm stroke, G3/4 port, and mounting interface.
This double-acting cylinder has a G3/4 port. It delivers 10053 N push and 9425 N pull at 0.5 MPa, 14074 N push at 0.7 MPa, 18095 N push at 0.9 MPa, and a theoretical max force of 2050 kgf at 1.0 MPa.
