This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X700TC, 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 SI160X700TC
The AirTAC SI160 Standard Cylinder SI160X700TC is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 700mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160X700TC, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X700TC
The AirTAC SI160X700TC is a discontinued double-acting ISO 15552 profile cylinder featuring a 160 mm bore, 700 mm stroke, and a TC trunnion mount. Delivering a push force of 10053 N at 0.5 MPa, it utilizes a G3/4 air port and a 50 mm adjustable air cushion at each end. As this legacy series has ended production, the direct replacement is the SAI160X700TC, which matches the original ISO 15552 mounting interface, bore, output force, and port size.
The SAI upgrade introduces an improved piston seal with two Y-shaped one-way elements for low start-up pressure and extended life. Note that this specific SKU lacks a magnet and cannot support position sensing. If higher temperatures are required, a Viton H seal option extends the operating range up to 150 C.

Where the Airtac SI160 Standard Cylinder SI160X700TC Is Used
Heavy Stamping Press
Drives large platens in metal forming operations where the 10053 N push force at 0.5 MPa is required to shape thick steel components.
Pallet Shuttle System
Moves loaded pallets along 700 mm conveyance tracks, utilizing the TC trunnion mount to accommodate structural articulation during transit.
Replacing the Airtac SI160 Standard Cylinder SI160X700TC with the SAI160X700TC
To replace the discontinued SI160X700TC, order the SAI160X700TC. Confirm the ISO 15552 TC trunnion mounting interface, 160 mm bore, 700 mm stroke, and G3/4 port (available in PT, G, or NPT threads). When sizing, consider the neighboring 125 mm bore for lower force needs or the 200 mm bore for higher demands; at 0.5 MPa, this 160 mm bore provides 10053 N push and 9425 N pull force. Because this SKU has no magnet, it cannot accept legacy CS1-B or DS1-B sensors. For load holding on air loss, note that a standard cylinder drifts and the cushion only decelerates; use an external rod lock, pilot check valve, or the SAIL/BSAI lock variants. Finally, for the 700 mm stroke, use external guides to prevent rod bending and manage side loads.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X700TC
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
