This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160BX95, 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 SI160BX95
The AirTAC Airtac SI160 Standard Cylinder SI160BX95 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 95mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160BX95, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160BX95
The AirTAC SI160BX95 is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 95 mm stroke. Delivering 10053 N push force at 0.5 MPa via a G3/4 port, it is directly replaced by the SAI160BX95 direct upgrade, which shares the exact same mounting interface, output, and dimensions.
The SAI successor features an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and long life. This specific SKU uses a SUS304 stainless steel rod (-B) for corrosion resistance, but lacks a magnet (-S) so it cannot accept position switches. For load holding, note that a standard cylinder drifts on air loss; use an external pilot check valve or the SAIL/BSAI lock variants.

Where the Airtac SI160 Standard Cylinder SI160BX95 Is Used
Heavy Stamping Press
Drives large heavy-duty stamping and forming dies requiring high thrust, utilizing the 10053 N push force at 0.5 MPa with robust ISO 15552 mounting.
Pallet Lift Gate
Actuates industrial pallet lift gates and heavy material elevators; note that an external pilot check valve is required to prevent load drift on air loss.
Injection Molding Clamp
Provides reliable clamping pressure for large injection molding fixtures, taking advantage of the SUS304 stainless rod for corrosive plant environments.
Replacing the Airtac SI160 Standard Cylinder SI160BX95 with the SAI160BX95
To replace this SI160BX95 with the SAI160BX95, verify the ISO 15552 mounting interface, 160 mm bore, 95 mm stroke, G3/4 port, and specific mounting accessory. This unit has a SUS304 stainless rod (-B) and no magnet, meaning it cannot support CS1-B/DS1-B sensors; if sensing is needed, order an SAI with the -S option. For sizing, neighbouring bores offer different capacities: a 125 mm bore provides 6136 N push at 0.5 MPa, while a 200 mm bore yields 15708 N. If your stroke was 300 mm or longer, ensure adequate guide support to prevent rod bending under side loads. Because a plain cylinder does not hold load without live air, consider the SAIL air-released lock or BSAI clamp-lock variants for safety-critical vertical lifts.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160BX95
- ✓ 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 SI160BX95 FAQ
Yes, the AirTAC SI160BX95 is discontinued. The direct replacement is the SAI160BX95. It is dimensionally interchangeable per ISO 15552, retaining the same 160 mm bore, 95 mm stroke, force, G3/4 port, and mounting interface.
