This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X210TC, 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 SI160X210TC
The AirTAC SI160 Standard Cylinder SI160X210TC is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 210mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160X210TC, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X210TC
The AirTAC SI160X210TC is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 210 mm stroke, delivering 10053 N push force at 0.5 MPa. The direct replacement is the SAI160X210TC, sharing the identical TC trunnion mount, G3/4 port, and M36x2 rod thread.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. Note this non-magnetic SKU cannot take a sensor; legacy CS1-B/DS1-B switches only fit the -S version.

Theoretical Output Force (Ø160mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 10053 N | 9425 N |
| 0.7 MPa | 14074 N | — |
| Max (@1.0 MPa) | 2050 kgf | |
The SAI160X210TC produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac SI160 Standard Cylinder SI160X210TC Is Used
Heavy Press Clamping
Generates 14074 N at 0.7 MPa to secure large steel fabrications during heavy-duty machining and robotic welding operations.
Injection Mould Ejection
Provides the robust 10053 N push force required to eject dense plastic automotive panels from large injection moulding tools.
Replacing the Airtac SI160 Standard Cylinder SI160X210TC with the SAI160X210TC
To replace the SI160X210TC, order the SAI160X210TC and verify the ISO 15552 TC trunnion interface, 210 mm stroke, and G3/4 port. The SAI family adds SAIL, SAIF, and BSAI lock variants the SI lacked. Since this is a non-magnetic SKU, it cannot accept a position switch. A plain cylinder drifts on air loss; for load holding, use an external rod lock or pilot check valve. At 210 mm stroke, rod bending is minimal, but always guide the load to prevent side-load wear. Neighbouring bores: 125 mm yields 6136 N push, while 200 mm yields 15708 N at 0.5 MPa.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X210TC
- ✓ 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 SI160X210TC FAQ
Yes, the SI160X210TC is discontinued. The direct replacement is the SAI160X210TC. It is dimensionally interchangeable per ISO 15552, retaining the exact 160 mm bore, 210 mm stroke, TC trunnion mount, and G3/4 port for a seamless fixture swap.
This double-acting cylinder features a G3/4 port and M36x2 rod thread. 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.
