This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X500SH, 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 SI100X500SH
The AirTAC Airtac SI100 Standard Cylinder SI100X500SH is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 500mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100X500SH, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100X500SH
The AirTAC SI100X500SH is a discontinued double-acting ISO 15552 profile cylinder with a 100mm bore and 500mm stroke. Delivering 3927N push force at 0.5MPa through a G1/2 port, it is replaced by the SAI100X500SH. This direct successor matches the exact mounting interface, stroke, and output force.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure. The -H suffix specifies a Viton seal for 0-150C high temps, while the -S magnet works with CS1-B/DS1-B switches. The SAI family also adds SAIL, SAIF, and BSAI lock variants.

Where the Airtac SI100 Standard Cylinder SI100X500SH Is Used
Heavy Press Clamping
Secures large steel plates in machining centers, utilizing the 3927N push force at 0.5MPa to prevent workpiece shifting during heavy milling.
Pallet Diversion
Extends 500mm to push heavy pallets off a main conveyor line onto a secondary packaging spur, requiring external guides to prevent rod bending.
High-Tact Forming
Operates a small forming die in elevated ambient temperatures up to 150C, relying on the Viton H seal to maintain structural integrity under thermal stress.
Replacing the Airtac SI100 Standard Cylinder SI100X500SH with the SAI100X500SH
To replace the SI100X500SH, order the SAI100X500SH. Verify the ISO 15552 interface, 100mm bore, 500mm stroke, G1/2 port, M20x1.5 rod thread, and your mounting accessory. The -S magnet enables CS1-B/DS1-B sensors, while the -H Viton seal handles 0-150C. If sizing down, an 80mm bore yields 2513N push at 0.5MPa; if sizing up, a 125mm bore yields 6136N. A 500mm stroke risks rod bending under side-load, so use external guides. A plain cylinder drifts on air loss; for load holding use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100X500SH
- ✓ 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 SI100X500SH FAQ
Yes, the SI100X500SH is discontinued. The direct replacement is the SAI100X500SH. It is dimensionally interchangeable per ISO 15552, matching the 100mm bore, 500mm stroke, G1/2 port, and mounting fixtures perfectly.
The 100mm bore features a G1/2 port and M20x1.5 rod thread. Force output is 3927N push and 3681N pull at 0.5MPa, 5497N push at 0.7MPa, 7068N push at 0.9MPa, and a theoretical max of 801kgf at 1.0MPa.
