This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160BX1155SH, 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 SI160BX1155SH
The AirTAC SI160 Standard Cylinder SI160BX1155SH is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 1155mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160BX1155SH, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160BX1155SH
The AirTAC SI160BX1155SH is a discontinued double-acting ISO 15552 profile cylinder featuring a 160 mm bore and 1155 mm stroke. It delivers 10053 N push force at 0.5 MPa through a G3/4 port. The direct replacement is the SAI160BX1155SH, retaining the exact ISO 15552 mounting interface, bore, stroke, force, and port size for seamless fixture integration.
This unit includes a SUS304 stainless rod (-B) and Viton H high-temperature seals (0-150 C). The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure. The -S magnet supports legacy CS1-B/DS1-B sensors.

Where the Airtac SI160 Standard Cylinder SI160BX1155SH Is Used
Heavy Stamp Press Feed
Drives heavy metal blanks into large stamping presses, utilizing the 10053 N push force and 1155 mm travel to reach deep into the tooling area.
Pallet Lift Ejection
Ejects loaded pallets from vertical lift stations, where the 512 kg vertical lift capacity and long stroke provide reliable heavy-goods discharge.
Large Mold Actuation
Actuates oversized industrial molding gates or core pulls, relying on the SUS304 stainless rod for corrosion resistance in humid foundry environments.
Replacing the Airtac SI160 Standard Cylinder SI160BX1155SH with the SAI160BX1155SH
To replace the SI160BX1155SH, order the SAI160BX1155SH. Confirm the ISO 15552 mounting interface, 1155 mm stroke, G3/4 port, and your specific mounting accessory (LB, FA, TC, etc.). The -S magnet enables CS1-B/DS1-B sensors, while the SAI uses current AirTAC switches. If you need load holding on air loss, note that a plain cylinder drifts; the cushion only decelerates. Use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant. At 1155 mm, prevent rod bending by using an external guide to manage side loads. For higher force, the 200 mm bore offers 15708 N [email protected]; for less, the 125 mm bore provides 6136 N.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160BX1155SH
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
