This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160BX10S, 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 SI160BX10S
The AirTAC SI160 Standard Cylinder SI160BX10S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 10mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160BX10S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160BX10S
The AirTAC SI160BX10S is a discontinued double-acting ISO 15552 profile cylinder with a 160mm bore and 10mm stroke. It delivers 10053 N push force at 0.5 MPa via a G3/4 port. This specific unit uses a SUS304 stainless piston rod for corrosion resistance and includes a magnet for legacy CS1-B/DS1-B sensors. AirTAC replaced the SI line with the SAI family.
Order the direct replacement: SAI160BX10S. It shares the same ISO 15552 mounting interface, bore, stroke, force, and port. The SAI upgrades the piston seal to two Y-shaped one-way elements for lower start-up pressure and longer life.

Theoretical Output Force (Ø160mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 10053 N | 9425 N |
| 0.7 MPa | 14074 N | — |

Where the Airtac SI160 Standard Cylinder SI160BX10S Is Used
Heavy Stamping Clamp
Secures large metal blanks in a hydraulic press using the 10053 N push force, with the short 10mm stroke providing rapid high-force clamping.
Mold Locking Pin
Acts as a robust locking pin for heavy injection molds, leveraging the corrosion-resistant SUS304 rod in humid production environments.
Press Platen Stop
Functions as a mechanical stop for a 512 kg vertical press platen, relying on the rigid 40mm rod to absorb sudden impact loads.
Replacing the Airtac SI160 Standard Cylinder SI160BX10S with the SAI160BX10S
To replace the SI160BX10S, order the SAI160BX10S, matching the ISO 15552 interface, 160mm bore, 10mm stroke, G3/4 port, and mounting accessories. Retain the -B SUS304 rod and -S magnet (the SAI uses current AirTAC switches instead of legacy CS1-B/DS1-B). When sizing, a 125mm bore yields 6136 N push at 0.5 MPa, while a 200mm bore yields 15708 N. Because this is a plain cylinder, it will not hold a load without live air; the 50mm adjustable cushion only decelerates. For load holding, use an external rod lock, a pilot check valve, or the SAIL/BSAI lock variants. The rod material options include carbon steel, SUS420J2, or SUS304.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160BX10S
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
