This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI63X60SH, 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 SI63X60SH
The AirTAC Airtac SI63 Standard Cylinder SI63X60SH 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 SAI63X60SH, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI63 Standard Cylinder SI63X60SH
The AirTAC SI63X60SH is a discontinued double-acting ISO 15552 profile cylinder with a 63mm bore and 60mm stroke. It delivers 1559 N push force at 0.5 MPa via a G3/8 port. The direct replacement is the SAI63X60SH, matching the exact bore, stroke, force, and ISO 15552 mounting interface.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. This unit includes the -S magnet for CS1-B/DS1-B sensors and the -H Viton seal for 0-150 C high-temp environments.

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 SAI63X60SH 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 SI63X60SH Is Used
Hot-End Clamping
Ideal for securing parts near thermal processes using the Viton H high-temperature seal rated for 0-150 C environments.
Mid-Range Diverting
Provides robust 1559 N push force at 0.5 MPa to deflect heavy packages on automated material handling lines.
Replacing the Airtac SI63 Standard Cylinder SI63X60SH with the SAI63X60SH
To replace the SI63X60SH, order the SAI63X60SH and confirm the ISO 15552 interface, 63mm bore, 60mm stroke, G3/8 port, and your mounting accessory. The -S magnet enables CS1-B/DS1-B legacy sensors, while the SAI uses current AirTAC switches. The -H Viton seal handles 0-150 C heat. For sizing, a 50mm bore gives 982 N push at 0.5 MPa, while an 80mm bore yields 2513 N. Note that a plain cylinder drifts without live air; for load holding, use an external pilot check valve or the SAIL/BSAI lock variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI63X60SH
- ✓ 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 SI63X60SH FAQ
Yes, the SI63X60SH is discontinued. The direct replacement is the SAI63X60SH. It is dimensionally interchangeable per ISO 15552, retaining the same 63mm bore, 60mm stroke, G3/8 port, and mounting interface.
The 63mm bore features a G3/8 port and delivers 1559 N push / 1402 N pull at 0.5 MPa, 2182 N push at 0.7 MPa, and a theoretical max of 318 kgf at 1.0 MPa. It uses a 20mm rod with an M16x1.5 thread.
