This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X100LB, 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 SI160X100LB
The AirTAC SI160 Standard Cylinder SI160X100LB is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 100mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160X100LB, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X100LB
The AirTAC SI160X100LB is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 100 mm stroke. Delivering 10053 N push force at 0.5 MPa via a G3/4 port, it is replaced by the SAI160X100LB. This direct successor matches the exact bore, stroke, force, port, and LB foot mounting interface.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. Note this no-S SKU cannot take a sensor.

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 SAI160X100LB 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 SI160X100LB Is Used
Heavy Press Operations
Applies 10053 N of thrust at 0.5 MPa for forming, stamping, and pressing heavy assemblies securely.
Large Clamp Fixtures
Secures oversized workpieces in machining centers using the LB foot mount and 9425 N pull force.
Replacing the Airtac SI160 Standard Cylinder SI160X100LB with the SAI160X100LB
To replace the SI160X100LB, order the SAI160X100LB. Confirm the ISO 15552 interface, 160 mm bore, 100 mm stroke, G3/4 port (PT/G/NPT), and LB foot mounting. This no-magnet SKU cannot accept a CS1-B/DS1-B sensor. Sizing both ways: a 125 mm bore yields 6136 N push at 0.5 MPa, while a 200 mm bore yields 15708 N. For load holding, a plain cylinder drifts without live air as cushions only decelerate; use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X100LB
- ✓ 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 SI160X100LB FAQ
Yes, the SI160X100LB is discontinued. The direct replacement is the SAI160X100LB. It is dimensionally interchangeable per ISO 15552, matching the 160 mm bore, 100 mm stroke, G3/4 port, and LB mounting interface.
It features a G3/4 port and M36x2 rod thread. 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, with a theoretical max of 2050 kgf at 1.0 MPa.
