This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI63BX60SH, 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 SI63BX60SH
The AirTAC Airtac SI63 Standard Cylinder SI63BX60SH 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 SAI63BX60SH, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI63 Standard Cylinder SI63BX60SH
The AirTAC SI63BX60SH is a discontinued double-acting ISO 15552 profile cylinder with a 63 mm bore and 60 mm stroke. It delivers 1559 N push force at 0.5 MPa through a G3/8 port. This specific SKU includes a SUS304 stainless steel rod (-B), a piston magnet (-S) for CS1-B/DS1-B switches, and a Viton H high-temperature seal rated for 0 to 150 C.
AirTAC replaced the SI family with the SAI series. The SAI63BX60SH is the direct replacement, matching the ISO 15552 mounting interface, stroke, force, and port size. The SAI features an upgraded piston seal with two Y-shaped one-way elements for lower start-up pressure and longer life.

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 SAI63BX60SH 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 SI63BX60SH Is Used
Stainless Rod Clamping
Ideal for packaging machinery requiring corrosion resistance, using the SUS304 rod to clamp components cleanly at 1559 N force.
High-Temperature Forming
The Viton H seal allows operation up to 150 C, making the 60 mm stroke suitable for positioning parts near thermal processing stations.
Transfer Diverting
Provides robust 79 kg vertical lift capability for diverting heavier product loads on manufacturing conveyor lines without fixture changes.
Replacing the Airtac SI63 Standard Cylinder SI63BX60SH with the SAI63BX60SH
To replace this discontinued SI63BX60SH, order the SAI63BX60SH. It drops directly into existing fixtures via the ISO 15552 mounting dimensions. Confirm you retain the B (SUS304 rod), S (magnet for current AirTAC switches), and H (Viton 0-150 C seal) options. The G3/8 port and M16x1.5 rod thread remain unchanged. If you need to scale, a 50 mm bore yields 982 N push at 0.5 MPa, while an 80 mm bore provides 2513 N. Remember that a standard cylinder drifts without live air; for load-holding, use an external pilot check valve or explore the SAIL (air-released lock) and BSAI (clamp-lock) variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI63BX60SH
- ✓ 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 SI63BX60SH FAQ
Yes, the SI63BX60SH is discontinued. The direct replacement is the SAI63BX60SH. It shares the exact same ISO 15552 mounting interface, 63 mm bore, 60 mm stroke, G3/8 port, and output force, fitting existing fixtures perfectly.
This 63 mm bore cylinder uses a G3/8 air port. It generates 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 maximum of 318 kgf at 1.0 MPa.
