This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI63X190CA, 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 SI63 Standard Cylinder SI63X190CA
The AirTAC Airtac SI63 Standard Cylinder SI63X190CA is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø63mm bore and 190mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI63X190CA, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI63 Standard Cylinder SI63X190CA
The AirTAC SI63X190CA is a discontinued double-acting ISO 15552 profile cylinder with a 63 mm bore, 190 mm stroke and CA clevis mounting. It delivers 1559 N push force at 0.5 MPa through a G3/8 port. AirTAC replaced this legacy unit with the SAI63X190CA, a direct upgrade retaining the exact interface, stroke and force.
The SAI upgrade features a new piston seal with two Y-shaped one-way elements for low start-up pressure and long life. It also introduces SAIL, SAIF and BSAI variants absent from the SI line. Note this specific SKU lacks a magnet, so it cannot accept CS1-B or DS1-B sensors.

Theoretical Output Force (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1402 N |
| 0.7 MPa | 2182 N | — |
| Max (@1.0 MPa) | 318 kgf | |
The SAI63X190CA produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac SI63 Standard Cylinder SI63X190CA Is Used
Clamp Actuation
Provides 1559 N of clamping force at 0.5 MPa for securing mid-weight steel components during machining operations.
Package Diversion
Drives a 190 mm stroke diverter arm to route heavy pallets on a production line without requiring external guides.
Material Lift Gates
Operates safety gates or mid-sized loading bay chutes where a 79 kg vertical lift capacity is sufficient.
Replacing the Airtac SI63 Standard Cylinder SI63X190CA with the SAI63X190CA
To replace the SI63X190CA, order the SAI63X190CA. Verify the ISO 15552 CA clevis mount, 190 mm stroke, G3/8 port and M16x1.5 rod thread. This SKU has no magnet (-S), meaning no position sensing is possible; order an SAI with S if you need CS1-B/DS1-B switches. Sizing both ways: a 50 mm bore yields 982 N push at 0.5 MPa, while an 80 mm bore yields 2513 N. If you need load holding on air loss, note the cushion only decelerates; use an external pilot check valve, rod lock, or the SAIL/BSAI lock variants. At 190 mm stroke, rod bending is minimal, but always guide the load to prevent side-load wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI63X190CA
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SI63 Standard Cylinder SI63X190CA FAQ
Yes, the SI63X190CA is discontinued. The direct replacement is the SAI63X190CA. It shares the identical ISO 15552 CA mounting interface, 63 mm bore, 190 mm stroke, output force and G3/8 port, fitting existing fixtures perfectly.
It features a G3/8 air port. Force output is 1559 N push and 1402 N pull at 0.5 MPa, 2182 N push at 0.7 MPa, 2805 N push at 0.9 MPa, and a maximum theoretical force of 318 kgf at 1.0 MPa.
