This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X750, 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 SI100X750
The AirTAC Airtac SI100 Standard Cylinder SI100X750 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 750mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100X750, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100X750
The AirTAC SI100X750 is a discontinued double-acting ISO 15552 profile cylinder with a 100 mm bore and 750 mm stroke. It delivers 3927 N push force at 0.5 MPa through a G1/2 port. The direct replacement is the SAI100X750, sharing the exact interface, force, and mounting.
The SAI upgrade features two Y-shaped one-way piston seals for low start-up pressure. This non-magnet SKU cannot take a sensor, unlike CS1-B equipped versions.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |
| Max (@1.0 MPa) | 801 kgf | |
The SAI100X750 produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac SI100 Standard Cylinder SI100X750 Is Used
Pallet Transfer
Indexes heavy pallets along a 750 mm stroke, utilizing the 3927 N push force at 0.5 MPa to overcome carton friction.
Packaging Divert
Actuates a large lane diverter arm over 750 mm, moving bulky boxed goods between parallel conveyor lines.
Replacing the Airtac SI100 Standard Cylinder SI100X750 with the SAI100X750
To replace the SI100X750, order the SAI100X750 keeping the identical ISO 15552 mounting interface, 750 mm stroke, and G1/2 port. Confirm your thread choice (PT/G/NPT) and mounting accessory (LB, FA, TC, etc.). This SKU lacks a magnet, so it cannot accept CS1-B/DS1-B sensors; order an -S variant if position detection is needed. For sizing, the 80 mm bore yields 2513 N push at 0.5 MPa, while the 125 mm bore offers 6136 N. At 750 mm stroke, use external guides to prevent rod bending and side-load damage. The air cushion only decelerates; for load holding on air loss, use an external pilot check valve or the SAIL/BSAI lock variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100X750
- ✓ 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 SI100X750 FAQ
Yes, the SI100X750 is discontinued. The direct replacement is the SAI100X750, which is dimensionally interchangeable per ISO 15552 with the same bore, stroke, force, G1/2 port, and mounting.
The G1/2 port bore delivers 3927 N push and 3681 N pull at 0.5 MPa, 5497 N push at 0.7 MPa, 7068 N push at 0.9 MPa, and a maximum theoretical force of 801 kgf at 1.0 MPa.
