This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X1350, 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 SI100X1350
The AirTAC Airtac SI100 Standard Cylinder SI100X1350 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 1350mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100X1350, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100X1350
The AirTAC SI100X1350 is a discontinued double-acting ISO 15552 profile cylinder with a 100mm bore and 1350mm stroke, delivering 3927N push force at 0.5MPa. The direct replacement is the SAI100X1350, retaining the exact G1/2 port, M20x1.5 thread, and mounting interface.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. Note this non-S SKU lacks a magnet and cannot accept a sensor.

Where the Airtac SI100 Standard Cylinder SI100X1350 Is Used
Long-Stroke Material Transfer
Pushes heavy pallets 1350mm between conveyor lines using 3927N of thrust at 0.5MPa.
High-Bay Ejection
Ejects large totes from automated storage racks where a 100mm bore and long reach are required.
Large Part Indexing
Indexes heavy automotive sub-assemblies along a 1.35-meter stroke path with external guides.
Replacing the Airtac SI100 Standard Cylinder SI100X1350 with the SAI100X1350
To replace the SI100X1350, order the SAI100X1350, confirming the ISO 15552 interface, 100mm bore, 1350mm stroke, G1/2 port, and mounting accessory. This non-magnetic SKU cannot take a sensor; if sensing is needed, specify an SAI with -S for CS1-B/DS1-B switches. Neighbouring bores: 80mm yields 2513N push, while 125mm yields 6136N at 0.5MPa. A plain cylinder drifts on air loss; for load holding use the SAIL lock, BSAI clamp-lock, or an external pilot check valve. At 1350mm, prevent rod bending by using an external guide to absorb side loads.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100X1350
- ✓ 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 SI100X1350 FAQ
