This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160BX200, 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 SI160BX200
The AirTAC SI160 Standard Cylinder SI160BX200 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 200mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160BX200, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160BX200
The AirTAC SI160BX200 is a discontinued double-acting ISO 15552 profile cylinder featuring a 160 mm bore and a 200 mm stroke. Built with an extruded aluminum barrel, it delivers 10053 N push force at 0.5 MPa and uses a G3/4 air port with a 50 mm adjustable air cushion at each end. This specific SKU has a SUS304 stainless piston rod (B option) for corrosion resistance but lacks a magnet, meaning it cannot accept position sensors.
You must replace it with the direct replacement SAI160BX200. It shares the exact ISO 15552 mounting interface, 200 mm stroke, force, and porting. The SAI upgrade features two Y-shaped one-way piston seals for low start-up pressure and long life. Note that a plain cylinder drifts without live air; use the SAIL or BSAI lock variants for load holding.

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 SI160BX200 Is Used
Heavy Press Clamping
Generates 14074 N of push force at 0.7 MPa to secure large metal workpieces in machining and stamping fixtures, utilizing the SUS304 rod in corrosive coolant environments.
Mold Actuation
Drives heavy industrial molds and tooling platforms, where the ISO 15552 mounting interface ensures rigid attachment to existing machine frames without redesign.
Replacing the Airtac SI160 Standard Cylinder SI160BX200 with the SAI160BX200
To replace the discontinued SI160BX200, order the SAI160BX200. Confirm the ISO 15552 mounting interface, the 160 mm bore, the 200 mm stroke, and the G3/4 port (available in PT, G, or NPT threads). Because this SKU lacks the -S magnet, it cannot support legacy CS1-B/DS1-B sensors; if sensing is needed, specify an SAI with a magnet. Sizing both ways: this bore yields 10053 N push at 0.5 MPa (14074 N at 0.7 MPa), while the neighboring 125 mm bore offers 6136 N push at 0.5 MPa. If your application requires load holding on air loss, a standard cylinder drifts—select the SAIL air-released lock or BSAI clamp-lock variant, or add an external pilot check valve. For this 200 mm stroke, side-load and rod-bending stresses are low, but ensure proper guide alignment to prevent premature seal wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160BX200
- ✓ 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 SI160BX200 FAQ
Yes, the SI160BX200 is discontinued. The direct replacement is the SAI160BX200. It is dimensionally interchangeable per ISO 15552, retaining the same 160 mm bore, 200 mm stroke, G3/4 port, and mounting interface, so it drops directly into existing fixtures.
This double-acting cylinder has a G3/4 air port. The force output is 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. It operates at 30-500 mm/s.
