This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI63X195, 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 SI63X195
The AirTAC Airtac SI63 Standard Cylinder SI63X195 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø63mm bore and 195mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI63X195, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI63 Standard Cylinder SI63X195
The AirTAC SI63X195 is a discontinued double-acting ISO 15552 profile cylinder with a 63 mm bore and 195 mm stroke. It delivers 1559 N push force at 0.5 MPa through a G3/8 port. The direct replacement is the SAI63X195, matching the interface, force and mounting exactly.
The SAI upgrade features two Y-shaped one-way piston seals for low start-up pressure and long life. This non-magnet SKU cannot take a sensor, unlike the CS1-B/DS1-B legacy switches used on -S models.

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 SAI63X195 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 SI63X195 Is Used
Clamp Actuation
Provides 1559 N of push force at 0.5 MPa to secure medium-duty workpieces during machining operations.
Package Diversion
Drives 195 mm stroke diverters to route moderate-weight goods across material handling lines.
Replacing the Airtac SI63 Standard Cylinder SI63X195 with the SAI63X195
To replace the SI63X195, order the SAI63X195 to retain the exact 63 mm bore, 195 mm stroke, M16x1.5 rod thread and G3/8 port. Confirm your ISO 15552 mounting accessory (LB, FA, TC) and thread standard (PT, G, NPT). Since this SKU lacks the -S magnet, it cannot support position sensing; you must add the -S suffix if switches are required. For sizing alternatives, 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 on pressure loss, use an external pilot check valve or explore the SAIL or BSAI lock variants. At 195 mm stroke, side-load risks are minimal, but ensure alignment to prevent rod bending.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI63X195
- ✓ 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 SI63X195 FAQ
Yes, the SI63X195 is discontinued. The direct replacement is the AirTAC SAI63X195. It is dimensionally interchangeable per ISO 15552, retaining the same 63 mm bore, 195 mm stroke, output force, G3/8 port and mounting interface.
The 63 mm bore features 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 force of 318 kgf at 1.0 MPa.
