This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X600SH, 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 SI160X600SH
The AirTAC SI160 Standard Cylinder SI160X600SH is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 600mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160X600SH, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X600SH
The AirTAC SI160X600SH is a discontinued double-acting ISO 15552 profile cylinder featuring a 160 mm bore and 600 mm stroke. It delivers a robust 10053 N push force at 0.5 MPa, utilizing a G3/4 air port and M36x2 rod thread. As an end-of-life product, its direct replacement is the SAI160X600SH, sharing identical mounting, force, and port specifications.
The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and extended life. This unit includes the -S magnet for CS1-B/DS1-B sensors and the -H Viton seal, raising the operating temperature range to 0-150 C.

Where the Airtac SI160 Standard Cylinder SI160X600SH Is Used
Heavy Machinery Forming
Drives large press platens and forming dies requiring high thrust over an extended 600 mm travel distance.
Pallet Transfer Systems
Indexes heavy loaded pallets through automated distribution centers using robust 160 mm bore power.
Automotive Assembly Lifts
Elevates engine blocks or chassis components on assembly lines, benefiting from the 0-150 C Viton seal.
Replacing the Airtac SI160 Standard Cylinder SI160X600SH with the SAI160X600SH
To replace the SI160X600SH, order the SAI160X600SH, confirming the ISO 15552 interface, 160 mm bore, 600 mm stroke, G3/4 port, and mounting accessories. The -S magnet and -H high-temp Viton seal must be specified. Neighbouring bores offer alternatives: a 200 mm bore yields 15708 N push at 0.5 MPa, while a 125 mm bore provides 6136 N. For this 600 mm stroke, external guides are recommended to prevent rod-bending and manage side loads. A plain cylinder drifts on air loss; for load holding, use an external rod lock, pilot check valve, or the SAIL/BSAI lock variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X600SH
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
