This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X1600, 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 SI100X1600
The AirTAC Airtac SI100 Standard Cylinder SI100X1600 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 1600mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100X1600, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100X1600
The AirTAC SI100X1600 is a discontinued double-acting ISO 15552 profile cylinder with a 100 mm bore and 1600 mm stroke. Because 1600 mm exceeds the 1500 mm standard maximum for this bore, it is a non-standard, made-to-order length. It features a G1/2 port, M20x1.5 rod thread, and delivers 3927 N push and 3681 N pull at 0.5 MPa. The direct replacement is the SAI100X1600, which shares the exact ISO 15552 mounting interface, output force, and porting to fit existing fixtures.
The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and long life. For applications needing load holding, the SAI line adds SAIL and BSAI lock variants the SI lacked. This specific SKU lacks a magnet and cannot accept a CS1-B/DS1-B sensor.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |

Where the Airtac SI100 Standard Cylinder SI100X1600 Is Used
Long-Stroke Transfer
Pushes heavy pallets between automated machining cells using the 3927 N force at 0.5 MPa over the full 1600 mm travel.
High-Bay Extraction
Extracts deep-rack totes, requiring external guides to manage the side-load risks inherent to this 1600 mm stroke.
Large Part Ejection
Ejects molded assemblies from heavy presses, utilizing the 100 mm bore's 801 kgf maximum theoretical output at 1.0 MPa.
Replacing the Airtac SI100 Standard Cylinder SI100X1600 with the SAI100X1600
To replace the SI100X1600, order the SAI100X1600, verifying your ISO 15552 mounting accessory (LB, FA, TC, etc.), G1/2 port threads (PT, G, or NPT), and the M20x1.5 rod end. This is a non-standard 1600 mm stroke exceeding the 1500 mm maximum, so expect made-to-order lead times. At 0.5 MPa it yields 3927 N push; if you need less force, the 80 mm bore provides 2513 N. Because this is a 1600 mm long stroke, you must use external guides to prevent rod bending and side-load damage. A plain cylinder drifts without live air; for load holding, use the SAIL lock variant or an external pilot check valve. Note this no-magnet SKU cannot support position sensing.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100X1600
- ✓ 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 SI100X1600 FAQ
Yes, the SI100X1600 is discontinued. The direct replacement is the SAI100X1600. It is dimensionally interchangeable per the ISO 15552 mounting interface, retaining the same 100 mm bore, 1600 mm stroke, G1/2 port, and output force to fit your existing fixtures.
This 100 mm bore cylinder uses a G1/2 port and provides 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 maximum theoretical force of 801 kgf at 1.0 MPa. Operating speed is 30-800 mm/s.
