This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X800TC, 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 SI160 Standard Cylinder SI160X800TC
The AirTAC SI160 Standard Cylinder SI160X800TC is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 800mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160X800TC, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X800TC
The AirTAC SI160X800TC is a discontinued double-acting ISO 15552 profile cylinder featuring a 160 mm bore and 800 mm stroke. It delivers 10053 N push and 9425 N pull at 0.5 MPa, operating at 30-500 mm/s with a G3/4 port and M36x2 rod thread. This legacy unit is replaced by the SAI160X800TC.
The SAI160X800TC is a direct replacement retaining the exact ISO 15552 mounting interface, TC trunnion mount, bore, stroke, force and port. It upgrades the piston seal to two Y-shaped one-way elements for low start-up pressure. Note this non-S SKU cannot take a sensor.

Theoretical Output Force (Ø160mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 10053 N | 9425 N |
| 0.7 MPa | 14074 N | — |
| Max (@1.0 MPa) | 2050 kgf | |
The SAI160X800TC produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac SI160 Standard Cylinder SI160X800TC Is Used
Heavy Machinery Erection
Lifts and positions large machinery frames requiring 10053 N push force over an 800 mm extension.
Bulk Material Diversion
Actuates heavy-duty diverter gates on high-capacity lines using the TC trunnion mount for pivot.
Palletizer Transfer
Shifts loaded pallets horizontally where the 9425 N pull force and long 800 mm stroke are essential.
Replacing the Airtac SI160 Standard Cylinder SI160X800TC with the SAI160X800TC
To replace the SI160X800TC, order the SAI160X800TC to keep the exact ISO 15552 TC trunnion interface, 160 mm bore, 800 mm stroke, G3/4 port and 10053 N output. Because this is a non-S model, it lacks a magnet and cannot accept CS1-B/DS1-B sensors; order an -S variant if position sensing is required. For sizing, the neighbouring 200 mm bore yields 15708 N push at 0.5 MPa, while dropping to 125 mm gives 6136 N. At 800 mm, provide an external guide to prevent rod bending and side-load wear. The cushion only decelerates; for load holding on air loss, use an external pilot check valve or the SAIL/BSAI lock variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X800TC
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SI160 Standard Cylinder SI160X800TC FAQ
Yes, the SI160X800TC is discontinued. The direct replacement is the SAI160X800TC. It is dimensionally interchangeable per ISO 15552, matching the 160 mm bore, 800 mm stroke, G3/4 port, TC mount and output force, so it fits existing fixtures directly.
This double-acting cylinder uses a G3/4 air port. The thrust is 10053 N push and 9425 N pull at 0.5 MPa, 14074 N push at 0.7 MPa, 18095 N push at 0.9 MPa, and a theoretical max of 2050 kgf at 1.0 MPa.
