This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X513S, 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 SI100X513S
The AirTAC SI100 Standard Cylinder SI100X513S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 513mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100X513S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100X513S
The AirTAC SI100X513S is a discontinued double-acting ISO 15552 profile cylinder with a 100mm bore and 513mm stroke. It delivers 3927N push force at 0.5MPa through a G1/2 port. The direct replacement is the SAI100X513S, matching the exact ISO 15552 mounting interface, stroke, force and accessories.
The SAI upgrade features two Y-shaped one-way piston seals for low start-up pressure and long life. The SAI family adds SAIL, SAIF and BSAI lock variants the SI lacked. Your -S magnet works with legacy CS1-B/DS1-B sensors.

Where the Airtac SI100 Standard Cylinder SI100X513S Is Used
Heavy Press Ejection
Provides the 3927N push at 0.5MPa needed to eject formed metal parts from heavy stamping dies, utilizing the full 513mm stroke to clear the press bed.
Pallet Diversion
Actuates large diverter arms on high-capacity roller conveyors, where the G1/2 port and 100mm bore deliver rapid 30-800mm/s cycling to route heavy pallets.
Vertical Lift Gates
Raises and lowers substantial mezzanine safety gates. The 513mm stroke accommodates high clearance, while the dual air cushions decelerate the load smoothly.
Replacing the Airtac SI100 Standard Cylinder SI100X513S with the SAI100X513S
To replace this SI100X513S, order the SAI100X513S. Confirm the ISO 15552 mounting accessory (LB, FA, CA, TC), the G1/2 port thread (PT/G/NPT) and the -S magnet. The SAI uses an upgraded dual Y-shaped piston seal. For sizing, a 100mm bore yields 3927N push at 0.5MPa; a neighbouring 80mm bore yields 2513N, while a 125mm bore yields 6136N. At 513mm stroke, use external guides to prevent rod bending and side-load wear. A plain cylinder drifts on air loss; for load holding, use an external pilot check valve or the SAIL/BSAI lock variant. The -S magnet supports CS1-B/DS1-B switches.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100X513S
- ✓ 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 SI100X513S FAQ
Yes, the SI100X513S is discontinued. The direct replacement is the AirTAC SAI100X513S. It is dimensionally interchangeable per ISO 15552, keeping the same 100mm bore, 513mm stroke, G1/2 port, 3927N force and mounting interface.
The 100mm bore uses a G1/2 air port and a 25mm piston rod. Force output is 3927N push and 3681N pull at 0.5MPa, 5497N push at 0.7MPa, 7068N push at 0.9MPa, and a theoretical maximum of 801kgf at 1.0MPa. Speed is 30-800mm/s.
