This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X150CB, 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 SI160X150CB
The AirTAC SI160 Standard Cylinder SI160X150CB is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 150mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160X150CB, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X150CB
The AirTAC SI160X150CB is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 150 mm stroke, delivering 10053 N push force at 0.5 MPa through a G3/4 port. AirTAC replaced it with the SAI160X150CB, a direct upgrade retaining the exact CB clevis mounting, M36x2 rod thread, and 50 mm cushions.
The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and extended life. For sensing, this specific SKU lacks a magnet and cannot accept a switch. For high heat, Viton H seals raise the limit to 150 C.

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 SI160X150CB Is Used
Heavy Press Forming
Drives large stamping dies with 10053 N thrust at 0.5 MPa, utilizing the 50 mm adjustable cushions to halt the 150 mm stroke smoothly.
Automated Welding Clamp
Holds heavy structural beams in place via the ISO 15552 CB clevis mount, delivering robust 9425 N pull force for fixturing.
Replacing the Airtac SI160 Standard Cylinder SI160X150CB with the SAI160X150CB
To replace the SI160X150CB, order the SAI160X150CB. Verify the ISO 15552 CB clevis interface, 150 mm stroke, G3/4 port, and M36x2 thread. Because this SKU lacks a magnet, no sensor can be fitted. Sizing both ways: the 125 mm bore yields 6136 N push at 0.5 MPa, while the 200 mm bore yields 15708 N. Note that a plain cylinder drifts on air loss—the cushion only decelerates. For held loads, use an external rod lock, pilot check valve, or the SAIL/BSAI lock variants. Operating speed is 30-500 mm/s.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X150CB
- ✓ 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 SI160X150CB FAQ
Yes, the SI160X150CB is discontinued. The direct replacement is the SAI160X150CB. It features the same ISO 15552 CB mounting interface, 160 mm bore, 150 mm stroke, output force, and G3/4 port, fitting existing fixtures perfectly.
The G3/4 port supplies a 160 mm bore yielding 10053 N push and 9425 N pull at 0.5 MPa. At 0.7 MPa push is 14074 N, and 18095 N at 0.9 MPa. The theoretical maximum force is 2050 kgf at 1.0 MPa.
