This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160BX175, 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 SI160BX175
The AirTAC SI160 Standard Cylinder SI160BX175 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 SAI160BX175, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160BX175
The AirTAC SI160BX175 is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 175 mm stroke. Delivering 10053 N push force at 0.5 MPa via a G3/4 port, this legacy unit is replaced by the SAI160BX175. The SUS304 stainless rod (-B) offers corrosion resistance, but lacking a -S suffix, this SKU cannot accept magnetic switches.
The SAI160BX175 is a direct replacement, matching the ISO 15552 mounting interface, M36x2 thread, and 50 mm cushions. The upgrade uses two Y-shaped one-way piston seals for low start-up pressure.

Where the Airtac SI160 Standard Cylinder SI160BX175 Is Used
Heavy Stamping
Drives large presses and stamping dies requiring 10053 N of push force at 0.5 MPa, utilizing the 175 mm stroke to form thick materials.
Pallet Handling
Indexes heavy pallets in automated distribution centers, where the SUS304 stainless rod resists environmental moisture and debris.
Automated Assembly
Actuates massive industrial fixtures and clamps, relying on the 50 mm adjustable air cushions to decelerate substantial moving masses.
Replacing the Airtac SI160 Standard Cylinder SI160BX175 with the SAI160BX175
To replace the SI160BX175, order the SAI160BX175. Verify the ISO 15552 mounting interface, 160 mm bore, 175 mm stroke, G3/4 port, and M36x2 thread. Because this SKU lacks a magnet, it cannot take sensors; if position feedback is needed, select an SAI160BX175S and use current AirTAC switches. The stainless -B rod suits corrosive environments. For load holding, note that a plain cylinder drifts on air loss—the cushion only decelerates. Use an external rod lock or pilot check valve, or specify the SAIL or BSAI lock variant. If downsizing, the 125 mm bore yields 6136 N push at 0.5 MPa; if upsizing, the 200 mm bore provides 15708 N.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160BX175
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
