This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X850TC, 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 SI160X850TC
The AirTAC SI160 Standard Cylinder SI160X850TC is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 850mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160X850TC, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X850TC
The AirTAC SI160X850TC is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 850 mm stroke. It delivers 10053 N push force at 0.5 MPa and uses a G3/4 port. As a legacy unit, it must be replaced by the current-production SAI160X850TC, which is a direct upgrade retaining the exact ISO 15552 mounting interface, TC trunnion mount, and output force.
The SAI replacement features an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and long life. Because this specific SI SKU lacks a magnet (-S), it cannot accept position sensors. For load holding, note that the air cushion only decelerates; you need an external rod lock or the SAIL/BSAI variant.

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 SAI160X850TC 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 SI160X850TC Is Used
Heavy Press Staging
Ideal for positioning heavy metal blanks into stamping presses, utilizing the 10053 N push force at 0.5 MPa to move substantial masses reliably.
Pallet Lift Stations
Drives large pallet lifts in automated storage systems, where the 850 mm stroke provides the extended travel needed for tiered access.
Bulk Material Diversion
Actuates heavy-duty diverter arms on conveyor lines, using the TC trunnion mount to handle the rotational moment of long-stroke operation.
Replacing the Airtac SI160 Standard Cylinder SI160X850TC with the SAI160X850TC
To replace the discontinued SI160X850TC, order the SAI160X850TC. Verify the ISO 15552 TC trunnion interface, 160 mm bore, 850 mm stroke, and G3/4 port. Because this SKU has no magnet, it cannot support legacy CS1-B/DS1-B sensors; if sensing is needed, specify an SAI with the S magnet option. Sizing both ways: a 125 mm bore yields 6136 N push at 0.5 MPa, while a 200 mm bore yields 15708 N. At 0.7 MPa this 160 mm bore reaches 14074 N. For the 850 mm stroke, use external guides to prevent rod bending and side loads. The standard cylinder does not hold load without air; use a pilot check valve or the SAIL lock variant for vertical holding.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X850TC
- ✓ 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 SI160X850TC FAQ
Yes, the SI160X850TC is discontinued. The direct replacement is the SAI160X850TC. It shares the same ISO 15552 mounting interface, 160 mm bore, 850 mm stroke, output force, G3/4 port, and TC trunnion mount, fitting existing fixtures perfectly.
This double-acting cylinder has a G3/4 port. The force ratings are: 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 maximum of 2050 kgf at 1.0 MPa.
