This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160BX175S, 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 SI160BX175S
The AirTAC SI160 Standard Cylinder SI160BX175S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 175mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160BX175S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160BX175S
The AirTAC SI160BX175S is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 175 mm stroke. Built for heavy-duty thrust, it delivers 10053 N push force at 0.5 MPa. The direct replacement is the SAI160BX175S, matching the ISO 15552 mounting interface, bore, stroke, output force, G3/4 port and accessories. The SAI upgrades the piston seal to two Y-shaped one-way elements for lower start-up pressure and longer life.
This -S SKU includes a piston magnet for legacy CS1-B/DS1-B sensors, while the -B rod denotes SUS304 stainless steel for corrosion resistance. Note that a plain cylinder drifts without live air; for load holding, specify the SAIL lock or BSAI clamp-lock variant.

Where the Airtac SI160 Standard Cylinder SI160BX175S Is Used
Heavy Stamping Press
Drives large dies and forming tools where the 10053 N push force at 0.5 MPa is required to shape thick metal plates.
Automated Assembly Line
Provides the robust linear motion needed to push heavy machinery components into precise alignment within large-scale manufacturing fixtures.
Pallet Handling Gate
Actuates heavy-duty diverter gates and lifting mechanisms for industrial pallets, utilizing the SUS304 stainless rod for environmental resilience.
Replacing the Airtac SI160 Standard Cylinder SI160BX175S with the SAI160BX175S
To replace the discontinued SI160BX175S, order the SAI160BX175S. Confirm the ISO 15552 mounting interface, the 175 mm stroke, the G3/4 port, and your mounting accessory (LB, FA, CA, TC, etc.). The -S magnet and -B SUS304 rod must be specified on the new order. Sizing both ways: this 160 mm bore yields 10053 N push at 0.5 MPa; if lower force is acceptable, a 125 mm bore provides 6136 N. Because this stroke is under 300 mm, severe rod-bending side loads are less critical than on longer units, but always guide the load to prevent seal wear. A standard cylinder does not hold load on air loss—the cushion only decelerates. For static holding, use an external pilot check valve or explore the SAIL air-released lock and BSAI clamp-lock variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160BX175S
- ✓ 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 SI160BX175S FAQ
Yes, the SI160BX175S is discontinued. The direct replacement is the SAI160BX175S. It is dimensionally interchangeable per ISO 15552, retaining the same 160 mm bore, 175 mm stroke, output force, G3/4 port and mounting interface. The SAI simply upgrades the piston seal to two Y-shaped one-way elements for longer life and lower start-up pressure.
This double-acting cylinder has a G3/4 port. The thrust ratings are: 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 maximum force of 2050 kgf at 1.0 MPa. It operates at 30-500 mm/s with a 50 mm adjustable air cushion at each end.
