This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X880S, 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 SI100X880S
The AirTAC Airtac SI100 Standard Cylinder SI100X880S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 880mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100X880S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100X880S
The AirTAC SI100X880S is a discontinued double-acting ISO 15552 profile cylinder featuring a 100mm bore, 880mm stroke, and a G1/2 air port. Delivering 3927 N of push force at 0.5 MPa, it is replaced by the SAI100X880S. This direct successor shares the exact ISO 15552 mounting interface, bore, stroke, and output force, fitting existing fixtures perfectly.
The SAI upgrade introduces a refined piston seal with two Y-shaped one-way elements for low start-up pressure and extended life. For load-holding, note that a standard cylinder drifts on air loss since cushions only decelerate; explore the SAIL lock or BSAI clamp-lock variants the SI lacked. The -S suffix provides a piston magnet for CS1-B/DS1-B switches, while Viton H seals raise operating temps to 150 C.

Where the Airtac SI100 Standard Cylinder SI100X880S Is Used
Heavy Material Transfer
Drives large pallets and heavy workpieces along assembly lines, utilizing the 3927 N push force at 0.5 MPa to move loads reliably over the 880mm extension.
Automated Storage Retrieval
Executes long-reach extraction and insertion of heavy totes in automated warehousing, where the 880mm stroke and robust 100mm bore profile barrel provide stable actuation.
Large Press Feed
Pushes substantial billets or sheet metal into forming presses, benefiting from adjustable end cushions to decelerate the heavy mass smoothly before the end of travel.
Replacing the Airtac SI100 Standard Cylinder SI100X880S with the SAI100X880S
To replace the SI100X880S, order the SAI100X880S, confirming the ISO 15552 interface, 100mm bore, 880mm stroke, G1/2 port (PT/G/NPT), and mounting accessory. The -S magnet enables CS1-B/DS1-B sensors. For sizing both ways: a neighbouring 80mm bore yields 2513 N [email protected], while a 125mm bore offers 6136 N. At 0.7 MPa this 100mm bore pushes 5497 N. Because the 880mm stroke exceeds 300mm, use external guides to prevent rod-bending and side-load damage. Remember, a plain cylinder does not hold load without live air; for secure holding, use an external rod lock, pilot check valve, or the SAIL/BSAI lock variants. The SAIF variant integrates a 4M valve for bores 32-100.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100X880S
- ✓ 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 SI100X880S FAQ
Yes, the SI100X880S is discontinued. The direct replacement is the SAI100X880S. It is a true ISO 15552 dimensionally interchangeable cylinder, maintaining the same 100mm bore, 880mm stroke, G1/2 port, and mounting interface, so it drops directly into existing fixtures.
The 100mm bore features a G1/2 air port. It 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 theoretical maximum force of 801 kgf at 1.0 MPa.
