This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X536CB, 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 SI160X536CB
The AirTAC SI160 Standard Cylinder SI160X536CB is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 536mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160X536CB, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X536CB
The AirTAC SI160X536CB is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 536 mm stroke. It delivers 10053 N push force at 0.5 MPa via a G3/4 port. The direct replacement is the SAI160X536CB, which shares identical ISO 15552 mounting interface dimensions, bore, stroke, force, port and CB clevis mounting.
The SAI upgrade features an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and long life. Because this SKU lacks the -S magnet, it cannot take a CS1-B or DS1-B sensor.

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 SI160X536CB Is Used
Heavy Machinery Forming
Drives large press dies and heavy forming platens requiring up to 10053 N of push force at 0.5 MPa.
Automated Assembly Presses
Provides steady clamping pressure for large component assembly, relying on the 50 mm adjustable air cushions to decelerate.
Replacing the Airtac SI160 Standard Cylinder SI160X536CB with the SAI160X536CB
To replace the SI160X536CB, order the SAI160X536CB. Verify the ISO 15552 interface, 160 mm bore, 536 mm stroke, G3/4 port, M36x2 rod thread and CB clevis mounting. This non-magnetic SKU cannot accept a sensor; if sensing is needed, order the -S variant. For sizing, neighbouring bores are 125 mm and 200 mm. At 0.5 MPa, the 125 mm bore pushes 6136 N, while the 200 mm bore pushes 15708 N. Because the 536 mm stroke exceeds 300 mm, use an external guide to prevent rod bending and side-load damage. A plain cylinder does not hold load without live air; for load holding on air loss, use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X536CB
- ✓ 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 SI160X536CB FAQ
Yes, the SI160X536CB is discontinued. The direct replacement is the SAI160X536CB. It shares the same ISO 15552 mounting interface, 160 mm bore, 536 mm stroke, output force, G3/4 port and CB clevis mounting, fitting existing fixtures perfectly.
The 160 mm bore delivers 10053 N push and 9425 N pull at 0.5 MPa, 14074 N push at 0.7 MPa, and a theoretical max of 2050 kgf at 1.0 MPa. Operating speed is 30-500 mm/s. It uses a G3/4 port and M36x2 rod thread.
