This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160BX35, 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 SI160BX35
The AirTAC Airtac SI160 Standard Cylinder SI160BX35 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 35mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160BX35, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160BX35
The AirTAC SI160BX35 is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 35 mm stroke. It delivers 10053 N push and 9425 N pull at 0.5 MPa, peaking at 2050 kgf. The direct is the SAI160BX35, sharing the exact G3/4 port, M36x2 thread, and ISO 15552 mounting interface.
The SAI160BX35 upgrades the piston seal to two Y-shaped one-way elements for low start-up pressure and long life. This specific SKU uses a SUS304 stainless steel rod (option B) and lacks a magnet, so it cannot accept CS1-B/DS1-B sensors.

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

Heavy Press Operations
Drives high-tonnage forming and stamping presses using 14074 N of push force at 0.7 MPa with a robust SUS304 rod.
Replacing the Airtac SI160 Standard Cylinder SI160BX35 with the SAI160BX35
To replace the SI160BX35, order the SAI160BX35. Verify the ISO 15552 mounting interface, 160 mm bore, 35 mm stroke, G3/4 port, and SUS304 rod. Since this SKU lacks a magnet (-S), it cannot support position sensing; add the S suffix if switches are needed. For sizing, neighboring bores are 125 mm (6136 N [email protected]) and 200 mm (15708 N). Note that a plain cylinder drifts on air loss; for load holding, use an external pilot check valve or the SAIL/BSAI lock variants. The 50 mm adjustable cushion decelerates loads at stroke ends.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160BX35
- ✓ 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 SI160BX35 FAQ
Yes, the SI160BX35 is discontinued. The direct replacement is the SAI160BX35. It shares the identical ISO 15552 mounting interface, 160 mm bore, 35 mm stroke, output force, and G3/4 port, fitting existing fixtures perfectly while upgrading the piston seal.
The 160 mm bore uses a G3/4 port. It generates 10053 N push and 9425 N pull at 0.5 MPa, 14074 N push at 0.7 MPa, and a theoretical maximum of 2050 kgf at 1.0 MPa. Operating speed is 30-500 mm/s.
