This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI63X60TC, 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 SI63X60TC
The AirTAC Airtac SI63 Standard Cylinder SI63X60TC 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 SAI63X60TC, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI63 Standard Cylinder SI63X60TC
The AirTAC SI63X60TC is a discontinued double-acting ISO 15552 profile cylinder with a 63mm bore and 60mm stroke. Delivering 1559N push force at 0.5MPa via a G3/8 port, it is replaced by the SAI63X60TC. This direct successor matches the TC trunnion mount, stroke, and output force exactly, fitting existing fixtures seamlessly.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. It also introduces SAIL, SAIF, and BSAI lock variants absent in the SI line. Note this SKU lacks a magnet and cannot accept a sensor.

Theoretical Output Force (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1402 N |
| 0.7 MPa | 2182 N | — |

Where the Airtac SI63 Standard Cylinder SI63X60TC Is Used
Mid-Tonnage Clamping
Secures heavy workpieces during machining operations, utilizing the 1559N push force at 0.5MPa to maintain rigid positioning against cutting loads.
Pallet Diversion
Actuates TC trunnion-mounted diverter arms on packaging lines, providing reliable 60mm stroke actuation to redirect heavy goods between conveyors.
Replacing the Airtac SI63 Standard Cylinder SI63X60TC with the SAI63X60TC
To replace the SI63X60TC, order the SAI63X60TC. Verify the ISO 15552 TC trunnion mounting dimensions, 63mm bore, 60mm stroke, and G3/8 port (PT/G/NPT thread options). Because this specific SKU lacks a magnet, it cannot support legacy CS1-B/DS1-B sensors; order an SAI with the S suffix if position sensing is required. Sizing both ways: a neighboring 50mm bore yields 982N push at 0.5MPa, while a 80mm bore yields 2513N. Remember that a plain cylinder drifts on air loss—the cushion only decelerates near stroke end. For load holding, specify an external pilot check valve or the SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI63X60TC
- ✓ 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 SI63X60TC FAQ
Yes, the SI63X60TC is discontinued. The direct replacement is the SAI63X60TC. It is dimensionally interchangeable per ISO 15552, retaining the exact 63mm bore, 60mm stroke, G3/8 port, TC trunnion mount, and output force to fit existing fixtures.
The 63mm bore features a G3/8 port, a 20mm rod, and M16x1.5 rod thread. Forces are 1559N push and 1402N pull at 0.5MPa, 2182N push at 0.7MPa, 2805N push at 0.9MPa, and a theoretical max of 318kgf at 1.0MPa. Operating speed is 30-800mm/s.
