This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X160SCB, 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 SI100 Standard Cylinder SI100X160SCB
The AirTAC Airtac SI100 Standard Cylinder SI100X160SCB is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 160mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100X160SCB, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100X160SCB
The AirTAC SI100X160SCB is a discontinued double-acting ISO 15552 profile cylinder with a 100mm bore and 160mm stroke. It delivers 3927N push at 0.5MPa through a G1/2 port. AirTAC replaced this legacy unit with the SAI100X160SCB, a direct upgrade retaining the exact CB clevis mount, M20x1.5 rod thread, and 36mm cushions.
The SAI replacement features an upgraded piston seal with two Y-shaped one-way elements for lower start-up pressure and longer life. The SAI family also adds SAIL, SAIF, and BSAI lock variants the SI lacked. Your -S suffix indicates a piston magnet for CS1-B/DS1-B sensors.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |

Where the Airtac SI100 Standard Cylinder SI100X160SCB Is Used
Heavy-Duty Pressing
Applies up to 7068N of force at 0.9MPa for seating bearings, stamping light-gauge metal, or pressing components into housings on an automated line.
Pallet Diversion
Uses the CB clevis mount to pivot a heavy diverter arm, smoothly redirecting loaded pallets with a 160mm stroke and adjustable end cushions.
Material Lift Gate
Actuates a 200kg vertical lift gate in a logistics hub, operating safely within the 2356N working load limit at standard 0.5MPa shop air pressure.
Replacing the Airtac SI100 Standard Cylinder SI100X160SCB with the SAI100X160SCB
To replace the SI100X160SCB, order the SAI100X160SCB. Verify your ISO 15552 interface dimensions, 100mm bore, 160mm stroke, G1/2 port, and CB clevis mounting. The -S magnet allows legacy CS1-B/DS1-B sensors, though the SAI uses current AirTAC switches. If you need more force than the 3927N push at 0.5MPa, step up to a 125mm bore; if less is required, an 80mm bore provides 2513N. Note that a plain cylinder drifts on air loss—the cushion only decelerates. For load holding, use an external pilot check valve or the SAIL/BSAI lock variant. At 160mm stroke, rod bending is low, but always guide external loads to prevent side-load wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100X160SCB
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SI100 Standard Cylinder SI100X160SCB FAQ
Yes, the SI100X160SCB is discontinued. The direct replacement is the AirTAC SAI100X160SCB. It is dimensionally interchangeable per ISO 15552, retaining the same 100mm bore, 160mm stroke, G1/2 port, and CB clevis mounting interface.
The 100mm bore features a G1/2 air port and a 25mm rod. It generates 3927N push and 3681N pull at 0.5MPa, 5497N push at 0.7MPa, 7068N push at 0.9MPa, and a theoretical maximum of 801kgf at 1.0MPa.
