This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X600CB, 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 SI160X600CB
The AirTAC Airtac SI160 Standard Cylinder SI160X600CB 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 SAI160X600CB, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X600CB
The AirTAC SI160X600CB is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 600 mm stroke. It delivers 10053 N push force at 0.5 MPa via a G3/4 port. The direct replacement is the SAI160X600CB, matching the interface, force, and CB clevis mount.
The SAI upgrade features two Y-shaped one-way piston seals for low start-up pressure and long life. This no-magnet SKU cannot take a sensor, and Viton H seals raise heat to 150 C.

Where the Airtac SI160 Standard Cylinder SI160X600CB Is Used
Heavy Machinery Forming
Drives large presses and forming fixtures requiring 10053 N thrust at 0.5 MPa, utilizing the 600 mm stroke for deep draw operations.
Bulk Goods Diversion
Actuates heavy-duty diverters on high-capacity conveyors, relying on the 50 mm adjustable air cushions to decelerate the 160 mm bore at stroke ends.
Replacing the Airtac SI160 Standard Cylinder SI160X600CB with the SAI160X600CB
To replace this SI with the SAI160X600CB, verify the 160 mm bore, 600 mm stroke, G3/4 port, and CB clevis mounting interface. Because this lacks the -S magnet, it cannot accept CS1-B/DS1-B sensors; order a magnet-equipped SAI if position sensing is needed. Sizing context: a 200 mm bore offers 15708 N push @0.5 MPa, while a 125 mm bore provides 6136 N. For the 600 mm stroke, use external guides to prevent rod bending and side-load damage. The air cushion only decelerates; it does not hold load 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 → SAI160X600CB
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SI160 Standard Cylinder SI160X600CB FAQ
Yes, the AirTAC SI160X600CB is discontinued. The direct replacement is the SAI160X600CB. It is dimensionally interchangeable per ISO 15552, retaining the same 160 mm bore, 600 mm stroke, G3/4 port, and CB clevis mounting interface.
At 0.5 MPa it pushes 10053 N and pulls 9425 N. Push force is 14074 N at 0.7 MPa, 18095 N at 0.9 MPa, and the theoretical max is 2050 kgf at 1.0 MPa. Operating speed is 30-500 mm/s. The rod thread is M36x2.
