This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI63X230CA, 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 SI63X230CA
The AirTAC Airtac SI63 Standard Cylinder SI63X230CA is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø63mm bore and 230mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI63X230CA, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI63 Standard Cylinder SI63X230CA
The AirTAC SI63X230CA is a discontinued double-acting ISO 15552 profile cylinder with a 63 mm bore and 230 mm stroke. It delivers 1559 N push force at 0.5 MPa through a G3/8 port. The direct replacement is the SAI63X230CA, featuring the exact same CA clevis mounting interface and dimensions. Because this specific SKU lacks a magnet (-S), it cannot accept a position sensor.
The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and long life. The SAI family also adds SAIL and BSAI lock variants the SI lacked.

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 SAI63X230CA 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 SI63X230CA Is Used
Clamp Actuation
Provides 1559 N of push force at 0.5 MPa to secure heavy workpieces in CNC machining fixtures.
Package Diversion
Drives a 230 mm stroke diverting arm to route medium-weight goods across material handling lines.
Pallet Stopping
Acts as a robust end-stop for inbound pallets, absorbing kinetic energy using its adjustable cushions.
Replacing the Airtac SI63 Standard Cylinder SI63X230CA with the SAI63X230CA
To replace the SI63X230CA, order the SAI63X230CA. Confirm the ISO 15552 CA clevis mount, 230 mm stroke, G3/8 port, and M16x1.5 rod thread. Since this SKU has no magnet, it cannot support CS1-B/DS1-B sensors; if sensing is needed, specify an SAI with an S suffix. Sizing both ways: a 50 mm bore yields 982 N push at 0.5 MPa, while an 80 mm bore yields 2513 N. Note that 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. At 230 mm stroke, guide external rods to prevent side-load bending.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI63X230CA
- ✓ 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 SI63X230CA FAQ
Yes, the SI63X230CA is discontinued. The direct replacement is the SAI63X230CA. It shares the identical ISO 15552 CA clevis mounting interface, 63 mm bore, 230 mm stroke, and G3/8 port, fitting existing fixtures perfectly.
The G3/8 port bore delivers push 1559 N and pull 1402 N at 0.5 MPa, push 2182 N at 0.7 MPa, push 2805 N at 0.9 MPa, and a theoretical max of 318 kgf at 1.0 MPa. The speed range is 30-800 mm/s.
