This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160BX15, 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 SI160BX15
The AirTAC SI160 Standard Cylinder SI160BX15 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 15mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160BX15, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160BX15
The AirTAC SI160BX15 is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 15 mm stroke. It delivers 10053 N push and 9425 N pull at 0.5 MPa via a G3/4 port. As an end-of-life unit, it is replaced by the SAI160BX15, a direct upgrade retaining the exact interface, force, and mounting.
The SAI160BX15 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) and lacks a magnet, so it cannot accept position switches.

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 SI160BX15 Is Used
High-Force Short-Stroke Clamping
Generates 10053 N of clamping force at 0.5 MPa for securing heavy fabrications during machining or welding operations.
Heavy-Duty Forming Press
Provides the robust 18095 N output at 0.9 MPa needed for short-travel stamping, bending, or riveting in metalworking lines.
Industrial Door Blocking
Acts as a high-capacity physical stop or short-throw blocker in large material handling systems, safely resisting 6032 N loads.
Replacing the Airtac SI160 Standard Cylinder SI160BX15 with the SAI160BX15
To replace the SI160BX15, order the SAI160BX15. It drops into existing fixtures via the same ISO 15552 mounting dimensions, 160 mm bore, 15 mm stroke, G3/4 port, and M36x2 rod thread. Because this 15 mm stroke is nonstandard, verify lead times. This SKU lacks a magnet (-S), so it cannot support legacy CS1-B/DS1-B sensors; order a magnet-equipped version if sensing is required. The SUS304 (-B) rod offers corrosion resistance versus standard carbon steel. For sizing, a 125 mm bore yields 6136 N push at 0.5 MPa, while a 200 mm bore provides 15708 N. Note that a plain cylinder drifts without live air; use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant for load holding.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160BX15
- ✓ 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 SI160BX15 FAQ
Yes, the AirTAC SI160BX15 is discontinued. The direct replacement is the SAI160BX15. It is a true ISO 15552 dimensionally interchangeable profile cylinder, retaining the same 160 mm bore, 15 mm stroke, G3/4 port, and mounting interface, but adds an upgraded two Y-shaped element piston seal.
This double-acting cylinder features a G3/4 air port and a 40 mm piston rod. It delivers 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 of 2050 kgf at 1.0 MPa.
