This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI63X60CA, 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 SI63X60CA
The AirTAC Airtac SI63 Standard Cylinder SI63X60CA is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø63mm bore and 60mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI63X60CA, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI63 Standard Cylinder SI63X60CA
The AirTAC SI63X60CA is a discontinued double-acting ISO 15552 profile cylinder with a 63 mm bore and 60 mm stroke, delivering 1559 N push force at 0.5 MPa via a G3/8 port. It is replaced by the SAI63X60CA, a direct upgrade retaining the exact ISO 15552 mounting interface, CA clevis, and M16x1.5 rod thread.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. This SKU lacks a magnet, so it cannot accept CS1-B/DS1-B sensors. For load holding, note the air cushion only decelerates; use SAIL or BSAI lock variants.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAI63X60CA carries the same ISO 15552 ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
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 SAI63X60CA 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 SI63X60CA Is Used
Clamp Actuation
Provides 1559 N of push force at 0.5 MPa to secure heavy workpieces in machining fixtures.
Package Diverting
Drives a 60 mm stroke diverter arm to route medium-weight goods across handling lines.
Gate Pushing
Operates short-stroke discharge gates on hoppers, moving bulk materials reliably.
Replacing the Airtac SI63 Standard Cylinder SI63X60CA with the SAI63X60CA
To replace the SI63X60CA, order the SAI63X60CA, confirming the ISO 15552 interface, 63 mm bore, 60 mm stroke, G3/8 port, and CA clevis mount. This non-magnet SKU cannot take sensors. For sizing, neighbouring bores offer different forces: a 50 mm bore provides 982 N push @0.5 MPa, while an 80 mm bore yields 2513 N. At 0.7 MPa this 63 mm cylinder outputs 2182 N. A plain cylinder drifts on air loss; for held loads use an external pilot check valve or the SAIL/BSAI lock variants. The 60 mm stroke avoids rod-bending side-load issues seen in longer strokes.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI63X60CA
- ✓ 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 SI63X60CA FAQ
Yes, the SI63X60CA is discontinued. The direct replacement is the SAI63X60CA. It shares the identical ISO 15552 mounting interface, 63 mm bore, 60 mm stroke, output force, G3/8 port, and CA clevis, fitting existing fixtures perfectly.
The 63 mm bore features a G3/8 port and M16x1.5 rod thread. It delivers 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 theoretical max force of 318 kgf at 1.0 MPa.
