This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X485H, 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 SI160X485H
The AirTAC SI160 Standard Cylinder SI160X485H is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 485mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160X485H, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X485H
The AirTAC SI160X485H is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 485 mm stroke. Delivering 10053 N push force at 0.5 MPa, it features a G3/4 port, M36x2 rod thread, and a high-temperature Viton H seal rated for 0 to 150 C. Because this SKU lacks a magnet, it cannot accept a position sensor.
Order the direct replacement SAI160X485H, which matches the ISO 15552 mounting interface, bore, stroke, force, and port. The SAI upgrades the piston seal to two Y-shaped one-way elements for low start-up pressure.

Where the Airtac SI160 Standard Cylinder SI160X485H Is Used
Heavy Pressing
Drives large stamping and forming presses requiring up to 14074 N of thrust at 0.7 MPa in high-temperature environments.
Pallet Handling
Shifts heavy loaded pallets on conveyors where the 9425 N pull force at 0.5 MPa easily overcomes friction.
Mold Clamping
Secures large injection molds, utilizing the 2050 kgf maximum theoretical force at 1.0 MPa for rigid holding.
Replacing the Airtac SI160 Standard Cylinder SI160X485H with the SAI160X485H
To replace the SI160X485H, order the SAI160X485H, confirming the ISO 15552 interface, 160 mm bore, 485 mm stroke, G3/4 port, and Viton H seal. Since this non-magnet SKU cannot take a sensor, add external physical stops if needed. For sizing, neighboring bores offer different forces: the 125 mm bore yields 6136 N push at 0.5 MPa, while the 200 mm bore yields 15708 N. A plain cylinder drifts on air loss—the cushion only decelerates—so use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant to hold loads. With a 485 mm stroke, use external guides to prevent rod bending and side loads. Speed is 30-500 mm/s.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X485H
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
