This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X1500SH, 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 SI100X1500SH
The AirTAC SI100 Standard Cylinder SI100X1500SH is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 1500mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100X1500SH, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100X1500SH
The AirTAC SI100X1500SH is a discontinued double-acting ISO 15552 profile cylinder with a 100mm bore and 1500mm stroke. Generating 3927N push force at 0.5MPa, it features a G1/2 port and M20x1.5 rod thread. The direct replacement is the SAI100X1500SH, matching the exact bore, stroke, force, port, and mounting interface.
This SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and longevity. The -H suffix denotes Viton seals for 0-150C high-temp environments, while the -S magnet supports CS1-B/DS1-B switches. For load holding, note the cushion only decelerates; use SAIL or BSAI lock variants.

Where the Airtac SI100 Standard Cylinder SI100X1500SH Is Used
Long-Stroke Material Push
Drives heavy workpieces across 1500mm transfer lines, relying on 3927N thrust at 0.5MPa to shift large assemblies between machining stations.
High-Temp Pressing
Performs clamping and pressing tasks in heated zones up to 150C, utilizing the Viton H seal to maintain integrity under thermal stress.
Automated Diversion
Actuates 1.5-meter routing gates on heavy-duty conveyors, using the integrated magnet for end-of-stroke position confirmation.
Replacing the Airtac SI100 Standard Cylinder SI100X1500SH with the SAI100X1500SH
To replace the SI100X1500SH, order the SAI100X1500SH. Verify the ISO 15552 mounting interface, G1/2 port, and 1500mm stroke. The SAI family adds SAIL, SAIF, and BSAI variants. At 0.5MPa, the 100mm bore yields 3927N push; the 80mm bore yields 2513N, and the 125mm yields 6136N. Because the cushion only decelerates, use an external rod lock or pilot check valve for load holding. At 1500mm, prevent rod bending by using an external guide to manage side loads.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100X1500SH
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
