This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X700CA, 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 SI160X700CA
The AirTAC Airtac SI160 Standard Cylinder SI160X700CA 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 SAI160X700CA, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X700CA
The AirTAC SI160X700CA is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 700 mm stroke. Delivering 10053 N push force at 0.5 MPa via a G3/4 port, it is replaced by the SAI160X700CA. This direct upgrade matches the CA clevis mount, M36x2 thread, and 50 mm cushions exactly.
The SAI uses an upgraded piston seal with two Y-shaped elements for low start-up pressure. Note this SKU lacks a magnet, so it cannot take a CS1-B/DS1-B sensor. Viton H seals raise temps to 150 C.

Where the Airtac SI160 Standard Cylinder SI160X700CA Is Used
Heavy Press Forming
Applies the 14074 N push force at 0.7 MPa to form thick metal components, utilizing the 700 mm stroke for deep-draw operations.
Pallet Lift Gates
Drives large vertical lifting gates in automated warehouses, safely moving loads up to the 512 kg vertical lift threshold.
Large Mold Handling
Shifts heavy injection molds along the 700 mm travel path, relying on the 50 mm adjustable cushions to decelerate the mass.
Replacing the Airtac SI160 Standard Cylinder SI160X700CA with the SAI160X700CA
To replace the SI160X700CA, order the SAI160X700CA. Confirm the ISO 15552 CA clevis mounting, 700 mm stroke, G3/4 port, and M36x2 thread. Because this SKU has no -S magnet, it cannot accept position sensors; if sensing is needed, select an SAI model with the magnet option. The 700 mm stroke demands external guides to prevent rod bending under side loads. For sizing, the 125 mm bore offers 6136 N [email protected], while the 200 mm bore provides 15708 N. A plain cylinder drifts on air loss; for load holding, use an external pilot check valve or the SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X700CA
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
