This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80X192, 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 SI80 Standard Air Cylinder SI80X192
The AirTAC SI80 Standard Air Cylinder SI80X192 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 192mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI80X192, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI80 Standard Air Cylinder SI80X192
The AirTAC SI80X192 is a discontinued double-acting ISO 15552 profile cylinder with an extruded aluminum barrel and adjustable air cushions at both ends. Delivering a push force of 2513 N at 0.5 MPa, it is replaced by the SAI80X192. This direct upgrade shares the exact same 80 mm bore, 192 mm stroke, G3/8 port, and ISO 15552 mounting interface.
The SAI replacement features an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and long life. This specific SKU lacks a magnet and cannot accept a sensor. Note that a plain cylinder drifts without live air; use the SAIL or BSAI lock variants for load holding.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAI80X192 carries the same ISO 15552 ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 N | — |
| Max (@1.0 MPa) | 513 kgf | |
The SAI80X192 produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac SI80 Standard Air Cylinder SI80X192 Is Used
Press Fit Assembly
Drives medium-tonnage press operations for seating bearings, delivering 2513 N of thrust at 0.5 MPa to seat components reliably.
Pallet Diverting
Actuates heavy diverters on packaging lines, using the 192 mm stroke to push standard pallets onto secondary routing tracks.
Material Lift Gates
Raises and lowers loaded lift gates, where the 80 mm bore provides enough push force to elevate goods without external hydraulics.
Replacing the Airtac SI80 Standard Air Cylinder SI80X192 with the SAI80X192
To replace the SI80X192, order the SAI80X192 and confirm your ISO 15552 mounting interface, 80 mm bore, 192 mm stroke, G3/8 port (PT/G/NPT), and mounting accessory. Because this SKU lacks a -S magnet, it cannot take a CS1-B/DS1-B sensor; if sensing is required, order the -S version. For sizing both ways, a 63 mm bore yields 1559 N push at 0.5 MPa, while a 100 mm bore yields 3927 N. The cushion only decelerates the piston; it does not hold load on air loss. For that, use an external rod lock, a pilot check valve, or the SAIL/BSAI lock variants. The SAIF self-valve variant is also available for bores up to 100 mm.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI80X192
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SI80 Standard Air Cylinder SI80X192 FAQ
Yes, the SI80X192 is discontinued. The direct replacement is the SAI80X192. It is dimensionally interchangeable per the ISO 15552 mounting interface, retaining the same 80 mm bore, 192 mm stroke, output force, G3/8 port, and mounting accessories.
This double-acting cylinder uses a G3/8 air port. At 0.5 MPa it provides 2513 N push and 2268 N pull force. At 0.7 MPa push is 3518 N, and at 0.9 MPa it is 4523 N. The theoretical maximum force is 513 kgf at 1.0 MPa.
