This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X1400, 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 SI160X1400
The AirTAC SI160 Standard Cylinder SI160X1400 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 1400mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160X1400, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X1400
The AirTAC SI160X1400 is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 1400 mm stroke. Delivering 10053 N push force at 0.5 MPa, it is replaced by the SAI160X1400. This direct successor shares the exact ISO 15552 mounting interface, G3/4 port, and M36x2 rod thread.
The SAI upgrade features two Y-shaped one-way piston seals for low start-up pressure. Note this non-magnet SKU cannot take sensors; legacy CS1-B/DS1-B switches are incompatible. For high heat, Viton H seals raise the limit to 150 C.

Where the Airtac SI160 Standard Cylinder SI160X1400 Is Used
Heavy Machinery Forming
Drives large presses and forming tools where the 10053 N push force at 0.5 MPa handles substantial metalworking resistance.
Automated Pallet Transfer
Shifts heavy loaded pallets along extended assembly lines, utilizing the 1400 mm stroke for long linear indexing movements.
Replacing the Airtac SI160 Standard Cylinder SI160X1400 with the SAI160X1400
To replace the SI160X1400, order the SAI160X1400, confirming the ISO 15552 interface, 1400 mm stroke, G3/4 port, and mounting accessory. This non-S SKU lacks a magnet and cannot accept position sensors. Sizing down, a 125 mm bore yields 6136 N at 0.5 MPa; sizing up to 200 mm provides 15708 N. At 1400 mm, use external guides to prevent rod bending and side loads. The air cushion only decelerates; for load holding on air loss, use an external rod lock, pilot check valve, or the SAIL/BSAI lock variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X1400
- ✓ 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 SI160X1400 FAQ
Yes, the SI160X1400 is discontinued. The direct replacement is the SAI160X1400. It is dimensionally interchangeable per ISO 15552, matching the 160 mm bore, 1400 mm stroke, force, G3/4 port, and mounting fixtures.
The G3/4 port bore delivers a push of 10053 N and pull of 9425 N at 0.5 MPa. At 0.7 MPa push is 14074 N, at 0.9 MPa it is 18095 N, and the theoretical max is 2050 kgf at 1.0 MPa. Speed is 30-500 mm/s.
