This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI63AX130S, 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 SI63AX130S
The AirTAC Airtac SI63 Standard Cylinder SI63AX130S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø63mm bore and 130mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI63AX130S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI63 Standard Cylinder SI63AX130S
The AirTAC SI63AX130S is a discontinued double-acting ISO 15552 profile cylinder with a 63 mm bore, 130 mm stroke, and SUS420J2 stainless steel rod. It delivers 1559 N push force at 0.5 MPa through a G3/8 port. AirTAC replaced this unit with the SAI63AX130S, a direct sharing the exact ISO 15552 mounting interface, stroke, output force, and porting.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. The built-in magnet supports legacy CS1-B/DS1-B sensors, while the SAI family adds SAIL lock, SAIF valve, and BSAI clamp variants.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAI63AX130S 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 SAI63AX130S 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 SI63AX130S Is Used
Stainless Rod Clamping
Ideal for machining fixtures requiring corrosion resistance, using the SUS420J2 rod to clamp parts with 1559 N of push force at 0.5 MPa.
Mid-Stroke Diversion
Perfectly suited for diverting packages on a line with its 130 mm stroke, providing positive actuation and smooth adjustable air cushion deceleration.
Replacing the Airtac SI63 Standard Cylinder SI63AX130S with the SAI63AX130S
To replace the SI63AX130S, order the SAI63AX130S. Verify your ISO 15552 mounting accessory (LB, FA, TC, etc.), the G3/8 port thread (PT/G/NPT), and the -S magnet requirement. The -A rod denotes SUS420J2 stainless steel; confirm if you need this corrosion resistance or the default carbon steel. For sizing, a 50 mm bore gives 982 N push @0.5 MPa, while an 80 mm bore yields 2513 N. Note that a plain cylinder drifts on air loss; the cushion only decelerates. For load holding, use an external pilot check valve or explore the SAIL or BSAI lock variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI63AX130S
- ✓ 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 SI63AX130S FAQ
Yes, the AirTAC SI63AX130S is discontinued. The direct replacement is the SAI63AX130S. It shares the identical ISO 15552 mounting interface, 63 mm bore, 130 mm stroke, force, and G3/8 port, fitting directly into existing fixtures.
This double-acting cylinder features a G3/8 air port. 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 maximum force of 318 kgf at 1.0 MPa.
