This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X260SH, 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 SI100X260SH
The AirTAC SI100 Standard Cylinder SI100X260SH is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 260mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100X260SH, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100X260SH
The AirTAC SI100X260SH is a discontinued double-acting ISO 15552 profile cylinder with a 100mm bore and 260mm stroke. It delivers 3927N push and 3681N pull at 0.5MPa, features a G1/2 port, and includes an S magnet for CS1-B/DS1-B switches. The direct replacement is the SAI100X260SH, matching the interface, force, and port.
This SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and long life. The H option specifies Viton seals, extending the operating range to 0-150C.

Where the Airtac SI100 Standard Cylinder SI100X260SH Is Used
Heavy-Duty Pressing
Applies 3927N of push force at 0.5MPa for seating bearings, stamping light components, or actuating heavy clamps in automated machining lines.
Pallet Handling
Drives robust 260mm stroke lifting arms or transfer gates in packaging conveyors, moving loads safely within the 2356N working limit.
High-Tact Automation
Executes 260mm transfer strokes in hot environments up to 150C using the Viton H seal option, maintaining reliable cycling in demanding foundry conditions.
Replacing the Airtac SI100 Standard Cylinder SI100X260SH with the SAI100X260SH
To replace the SI100X260SH, order the SAI100X260SH. Confirm the ISO 15552 mounting interface, 100mm bore, 260mm stroke, G1/2 port, and your specific mounting accessory. The S magnet enables current AirTAC switches, replacing legacy CS1-B/DS1-B sensors. If sizing up or down, neighboring bores are 80mm and 125mm. Note that a plain cylinder drifts on air loss; the cushion only decelerates. For load holding, use an external rod lock, pilot check valve, or the SAIL/BSAI lock variants. The SAIF variant adds a built-in valve for bores up to 100mm.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100X260SH
- ✓ 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 SI100X260SH FAQ
Yes, the SI100X260SH is discontinued. The direct replacement is the SAI100X260SH. It is dimensionally interchangeable per ISO 15552, retaining the same 100mm bore, 260mm stroke, G1/2 port, and mounting interface.
The 100mm bore uses a G1/2 port. It generates 3927N push and 3681N pull at 0.5MPa, 5497N push at 0.7MPa, 7068N at 0.9MPa, and a theoretical max of 801kgf at 1.0MPa.
