This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X800SCB, 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 SI100X800SCB
The AirTAC Airtac SI100 Standard Cylinder SI100X800SCB is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 800mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100X800SCB, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100X800SCB
The AirTAC SI100X800SCB is a discontinued double-acting ISO 15552 profile cylinder with an 800 mm stroke, delivering 3927 N push and 3681 N pull at 0.5 MPa. It features a G1/2 port, M20x1.5 rod thread, and a built-in magnet for CS1-B/DS1-B sensors. You must order the direct replacement SAI100X800SCB, which shares the exact CB clevis mounting, 100 mm bore, and output force.
The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and long life. The SAI family also adds SAIL, SAIF, and BSAI lock variants the SI lacked. If high heat is a factor, specify the Viton H seal for 0-150 C operation.

Where the Airtac SI100 Standard Cylinder SI100X800SCB Is Used
Heavy Material Transfer
Drives large pallets or heavy assemblies over 800 mm on packaging lines, utilizing the 3927 N push force at 0.5 MPa to move loads reliably without stalling.
Automated Warehousing
Actuates long-travel lifting or pusher arms in storage retrieval systems, where the CB clevis mount absorbs pivot stress during lateral load shifts.
Large Press Feeding
Feeds heavy sheet metal or blanks into stamping presses, relying on the 36 mm adjustable air cushions to decelerate the 25 mm rod smoothly at stroke ends.
Replacing the Airtac SI100 Standard Cylinder SI100X800SCB with the SAI100X800SCB
To replace this SI100X800SCB, order the SAI100X800SCB. Confirm the ISO 15552 interface, 100 mm bore, 800 mm stroke, G1/2 port, CB clevis mount, and the -S magnet for current AirTAC switches. A plain cylinder drifts on air loss—the cushion only decelerates—so use an external rod lock or pilot check valve for load holding, or step up to the SAIL/BSAI lock variant. At 800 mm, prevent rod bending by adding external guides to handle side loads. For higher force, the 125 mm bore gives 6136 N push at 0.5 MPa; for less, the 80 mm bore provides 2513 N.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100X800SCB
- ✓ 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 SI100X800SCB FAQ
Yes, the AirTAC SI100X800SCB is discontinued. The direct replacement is the SAI100X800SCB. It is dimensionally interchangeable per ISO 15552, matching the 100 mm bore, 800 mm stroke, G1/2 port, CB clevis mount, and output force for existing fixtures.
The G1/2 port bore delivers a push force of 3927 N and a pull force of 3681 N at 0.5 MPa. At 0.7 MPa the push is 5497 N, and at 0.9 MPa it is 7068 N. The theoretical maximum force is 801 kgf at 1.0 MPa, with an operating speed of 30-800 mm/s.
