This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X415CB, 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 SI100X415CB
The AirTAC Airtac SI100 Standard Cylinder SI100X415CB is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 415mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100X415CB, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100X415CB
The AirTAC SI100X415CB is a discontinued double-acting ISO 15552 profile cylinder featuring a 100 mm bore, 415 mm stroke, and CB clevis mounting. Delivering 3927 N push force at 0.5 MPa, it is replaced by the SAI100X415CB. This direct upgrade matches the exact bore, stroke, G1/2 port, and ISO 15552 mounting interface.
The SAI replacement features an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and long life. It also adds SAIL, SAIF, and BSAI lock variants absent in the SI line. Note this non-magnet SKU cannot take a sensor.

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 SI100X415CB Is Used
Heavy Stamping Press
Drives heavy stamping actuators, utilizing the 3927 N push force at 0.5 MPa to form thick metal components reliably.
Material Diversion Gate
Actuates large routing gates on high-capacity conveyors, where the CB clevis mount absorbs pivot stress over the 415 mm travel.
Replacing the Airtac SI100 Standard Cylinder SI100X415CB with the SAI100X415CB
To replace the SI100X415CB, order the SAI100X415CB. Confirm the ISO 15552 CB clevis mounting, 415 mm stroke, and G1/2 port (PT/G/NPT). Because this SKU lacks a magnet, it cannot accept CS1-B/DS1-B sensors; if sensing is needed, specify an SAI model with the -S magnet option. The 100 mm bore yields 3927 N push at 0.5 MPa; sizing down, an 80 mm bore provides 2513 N. For load holding, note a plain cylinder drifts on air loss—the cushion only decelerates. Use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant. With a 415 mm stroke, use external guides to prevent rod bending and side loads.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100X415CB
- ✓ 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 SI100X415CB FAQ
Yes, the SI100X415CB is discontinued. The direct replacement is the SAI100X415CB. It shares the identical ISO 15552 mounting interface, 100 mm bore, 415 mm stroke, output force, and G1/2 port, fitting existing fixtures perfectly.
This double-acting cylinder has a 25 mm rod, M20x1.5 thread, G1/2 port, 36 mm cushion, and 30-800 mm/s speed. Force ratings are: push 3927 N and pull 3681 N at 0.5 MPa, push 5497 N at 0.7 MPa, push 7068 N at 0.9 MPa, and a theoretical max of 801 kgf at 1.0 MPa.
