This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160BX600S, 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 SI160BX600S
The AirTAC SI160 Standard Cylinder SI160BX600S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 600mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160BX600S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160BX600S
The AirTAC SI160BX600S is a discontinued double-acting ISO 15552 profile cylinder featuring a 160 mm bore, 600 mm stroke, and a SUS304 stainless piston rod. Delivering 10053 N push force at 0.5 MPa, it is replaced by the SAI160BX600S. This direct successor matches the G3/4 port, M36x2 thread, and ISO 15552 mounting interface.
The SAI upgrade features two Y-shaped one-way piston seals for low start-up pressure and long life. The SAI family also adds SAIL and BSAI lock variants absent in the SI line. Your -S magnet works with legacy CS1-B/DS1-B sensors.

Where the Airtac SI160 Standard Cylinder SI160BX600S Is Used
Heavy Stamp Presses
Drives large stamping dies requiring 10053 N push force at 0.5 MPa, utilizing the 600 mm stroke to fully clear the tooling area for robotic loading.
Large Clamp Fixtures
Secures heavy weldments during machining, relying on adjustable 50 mm air cushions to decelerate the massive 160 mm piston at stroke ends.
Replacing the Airtac SI160 Standard Cylinder SI160BX600S with the SAI160BX600S
To replace the SI160BX600S, order the SAI160BX600S. Verify the ISO 15552 mounting interface, 600 mm stroke, G3/4 port, and -S magnet. The -B rod denotes SUS304 stainless steel. If downsizing, a 125 mm bore yields 6136 N push at 0.5 MPa; if upsizing, 200 mm provides 15708 N. For the 600 mm stroke, use external guides to prevent rod bending and side-load damage. A plain cylinder drifts on air loss; for load holding, use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160BX600S
- ✓ 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 SI160BX600S FAQ
Yes, the SI160BX600S is discontinued. The direct replacement is the SAI160BX600S. It is dimensionally interchangeable per the ISO 15552 mounting interface, retaining the exact 160 mm bore, 600 mm stroke, force, G3/4 port, and mounting accessories.
The bore is 160 mm with a G3/4 air port. Force output is 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 of 2050 kgf at 1.0 MPa. Operating speed is 30-500 mm/s.
