This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X100, 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 SI160X100
The AirTAC Airtac SI160 Standard Cylinder SI160X100 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 100mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160X100, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X100
The AirTAC SI160X100 is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 100 mm stroke. It delivers 10053 N push force at 0.5 MPa through a G3/4 port. As this legacy unit is end-of-life, the direct replacement is the SAI160X100, matching the exact bore, stroke, force, port, and ISO 15552 mounting interface for seamless fixture integration.
The SAI upgrade features a modernized piston seal with two Y-shaped one-way elements for low start-up pressure and extended life. Note that this specific SKU lacks a magnet (-S) and cannot accept position sensors. For high-temperature environments up to 150 C, a Viton H seal option is available.

Where the Airtac SI160 Standard Cylinder SI160X100 Is Used
Heavy Press Operations
Generates 14074 N at 0.7 MPa for forming, stamping, and pressing dense materials in automated fabrication lines.
Pallet Handling
Provides the robust push force required to index heavy loaded pallets along transfer conveyors in distribution hubs.
Industrial Clamp Systems
Secures large workpieces during machining, utilizing the 100 mm stroke to cycle quickly within heavy-duty fixtures.
Replacing the Airtac SI160 Standard Cylinder SI160X100 with the SAI160X100
To replace the discontinued SI160X100, order the SAI160X100. Verify your ISO 15552 mounting accessory (LB, FA, CA, TC) and thread type (PT, G, or NPT) match. Because this SKU has no magnet, it cannot support legacy CS1-B/DS1-B sensors; if position detection is needed, select an SAI160X100S. Sizing checks: the 160 mm bore yields 10053 N push at 0.5 MPa, while the neighboring 125 mm bore offers 6136 N. If your application requires load holding on air loss, note that the standard cushion only decelerates; you must use an external rod lock, a pilot check valve, or the SAIL/BSAI lock variants. The 40 mm rod and M36x2 thread handle high side loads, but for any stroke over 300 mm, add guide rails to prevent rod bending.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X100
- ✓ 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 SI160X100 FAQ
Yes, the AirTAC SI160X100 is discontinued. The direct replacement is the SAI160X100. It is dimensionally interchangeable per ISO 15552, retaining the same 160 mm bore, 100 mm stroke, output force, G3/4 port, and mounting interface.
This double-acting cylinder features a G3/4 port. It delivers a push force of 10053 N and a pull force of 9425 N at 0.5 MPa. At 0.7 MPa the push force is 14074 N, and 18095 N at 0.9 MPa. The theoretical maximum force is 2050 kgf at 1.0 MPa.
