This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X160TC, 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 SI100X160TC
The AirTAC SI100 Standard Cylinder SI100X160TC is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 160mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100X160TC, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100X160TC
The AirTAC SI100X160TC is a discontinued double-acting ISO 15552 profile cylinder with a 100mm bore and 160mm stroke. Delivering 3927N push force at 0.5MPa through a G1/2 port, it is replaced by the SAI100X160TC. This direct successor matches the TC trunnion mount, M20x1.5 rod thread and 36mm cushions.
The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and long life. The original SI line lacked the SAIL lock, SAIF valve and BSAI clamp variants now available. Since this no-S SKU lacks a magnet, it cannot take a 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 SI100X160TC Is Used
Heavy Press Clamping
Secures large metal castings during machining operations using its 3927N push force at 0.5MPa.
Pallet Diversion
Handles robust TC trunnion-mounted routing of heavy unit goods along high-capacity assembly lines.
Replacing the Airtac SI100 Standard Cylinder SI100X160TC with the SAI100X160TC
To replace the SI100X160TC, order the SAI100X160TC to retain the exact ISO 15552 TC trunnion interface, 100mm bore, 160mm stroke and G1/2 port. Because this specific SKU has no magnet, it cannot accept a CS1-B or DS1-B switch; add the S suffix if position sensing is required. For sizing, a neighbouring 80mm bore yields 2513N push at 0.5MPa, while a 125mm bore offers 6136N. Note that a plain cylinder drifts on air loss; the cushions only decelerate. For load holding, specify the SAIL lock, BSAI clamp-lock variant, or an external pilot check valve.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100X160TC
- ✓ 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 SI100X160TC FAQ
Yes, the SI100X160TC is discontinued. The direct replacement is the SAI100X160TC. It provides a true ISO 15552 dimensional match, keeping the same 100mm bore, 160mm stroke, G1/2 port and TC mounting interface.
This double-acting cylinder uses a G1/2 port. It delivers 3927N push and 3681N pull at 0.5MPa, 5497N push at 0.7MPa, 7068N push at 0.9MPa, and a theoretical maximum force of 801kgf at 1.0MPa.
