This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80X60CA, 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 SI80X60CA
The AirTAC SI80 Standard Air Cylinder SI80X60CA is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 60mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI80X60CA, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI80 Standard Air Cylinder SI80X60CA
The AirTAC SI80X60CA is a discontinued double-acting ISO 15552 profile cylinder. It delivers 2513 N push force at 0.5 MPa through an 80 mm bore and 60 mm stroke. The direct replacement is the SAI80X60CA, matching the CA clevis mount, G3/8 port, and M20x1.5 rod thread.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. Because this SI SKU lacks the -S magnet, it cannot take a CS1-B/DS1-B sensor. The SAI family also adds SAIL, SAIF, and BSAI lock variants.

Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 N | — |

Where the Airtac SI80 Standard Air Cylinder SI80X60CA Is Used
Clamp Actuation
Provides 2513 N of secure clamping force for heavy machining fixtures, utilizing the CA clevis to accommodate swing alignment during the 60 mm stroke.
Package Diversion
Drives robust routing gates on high-throughput packaging lines, where the 80 mm bore delivers decisive force to redirect heavy cartons without hesitation.
Pallet Stopping
Halts loaded pallets at workflow stations using a 60 mm stroke, relying on the adjustable air cushion to decelerate impacts smoothly at the end of travel.
Replacing the Airtac SI80 Standard Air Cylinder SI80X60CA with the SAI80X60CA
To replace the SI80X60CA, order the SAI80X60CA. It drops into existing fixtures via the ISO 15552 mounting interface with the CA clevis intact. Confirm the G3/8 port and M20x1.5 thread. Since this SKU lacks a magnet, position sensing is impossible; order a -S SAI if you need current AirTAC switches. Sizing both ways: a 63 mm bore yields 1559 N push at 0.5 MPa, while a 100 mm bore yields 3927 N. A plain cylinder drifts on air loss—the cushion only decelerates. For load holding, use an external pilot check valve or the SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI80X60CA
- ✓ 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 SI80X60CA FAQ
Yes, the SI80X60CA is discontinued. The direct replacement is the SAI80X60CA. It is dimensionally interchangeable per ISO 15552, retaining the same 80 mm bore, 60 mm stroke, CA clevis mount, and G3/8 port. You simply order the SAI equivalent.
The 80 mm bore uses a G3/8 air port and a 25 mm piston rod. It generates 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, and 4523 N push at 0.9 MPa. The theoretical maximum force is 513 kgf at 1.0 MPa.
