This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X330N, 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 SI100X330N
The AirTAC Airtac SI100 Standard Cylinder SI100X330N is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 330mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100X330N, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100X330N
The AirTAC SI100X330N is a discontinued double-acting ISO 15552 profile cylinder with a 100 mm bore and 330 mm stroke. It delivers 3927 N push and 3681 N pull at 0.5 MPa through a G1/2 port. The direct replacement is the SAI100X330N, which shares identical mounting, force, and interface dimensions. This specific SKU uses an NBR seal (operating -20 to +70 C) and lacks a magnet, meaning it cannot accept position sensors.
The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and extended life. If you need load holding on air loss, the standard cushion only decelerates; you must use an external pilot check valve or the SAIL/BSAI lock variants.

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 SI100X330N Is Used
Heavy-Duty Pressing
Applies the 3927 N push force at 0.5 MPa to seat bearings or assemble heavy mechanical components securely.
Material Diversion
Actuates large diverters or stops on high-capacity conveyors, utilizing the G1/2 port for rapid cycling.
Replacing the Airtac SI100 Standard Cylinder SI100X330N with the SAI100X330N
To replace the SI100X330N, order the SAI100X330N and verify your ISO 15552 mounting interface, G1/2 port, and M20x1.5 rod thread. Because this SKU lacks a magnet (-S), it cannot support legacy CS1-B/DS1-B sensors; order a magnet-equipped SAI if sensing is required. Sizing both ways: the neighboring 80 mm bore yields 2513 N push at 0.5 MPa, while the 125 mm bore yields 6136 N. At 0.7 MPa, this 100 mm bore reaches 5497 N. With a 330 mm stroke, prevent rod bending by using external guides to manage side loads. Remember that a plain cylinder drifts without live air; for secure holding, explore the SAIL or BSAI lock variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100X330N
- ✓ 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 SI100X330N FAQ
Yes, the SI100X330N is discontinued. The direct replacement is the SAI100X330N. It is dimensionally interchangeable per ISO 15552, retaining the same 100 mm bore, 330 mm stroke, 3927 N force, G1/2 port, and mounting interface.
It features a G1/2 port and delivers a push force of 3927 N and pull of 3681 N at 0.5 MPa. At 0.7 MPa push is 5497 N, and 7068 N at 0.9 MPa. The theoretical maximum force is 801 kgf at 1.0 MPa.
