This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI63X160CA, 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 SI63X160CA
The AirTAC Airtac SI63 Standard Cylinder SI63X160CA is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø63mm bore and 160mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI63X160CA, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI63 Standard Cylinder SI63X160CA
The AirTAC SI63X160CA is a discontinued double-acting ISO 15552 profile cylinder with a 63mm bore and 160mm stroke. It delivers 1559N push force at 0.5MPa via a G3/8 port. The direct replacement is the SAI63X160CA, matching the CA clevis mount, M16x1.5 rod, and output exactly.
The SAI upgrade features two Y-shaped one-way piston seals for low start-up pressure. This no-S SKU lacks a magnet and cannot take a sensor. For locked loads, explore the SAIL or BSAI variants, as cushions only decelerate.

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 SAI63X160CA 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 SI63X160CA Is Used
Clamp Actuation
Secures heavy workpieces during machining using the 1559N push force, pivoting smoothly via the CA clevis mount.
Package Diversion
Drives mechanical gates or pushers on assembly lines, moving loads safely under the 935N working limit.
Pallet Lift Stops
Acts as a robust physical stop or positioning index in material handling, decelerating moving pallets effectively.
Replacing the Airtac SI63 Standard Cylinder SI63X160CA with the SAI63X160CA
To replace this SI63X160CA, order the SAI63X160CA. It drops into existing fixtures via the ISO 15552 interface, retaining the 63mm bore, 160mm stroke, G3/8 port, and CA clevis mounting. When sizing, neighboring bores offer alternatives: a 50mm yields 982N [email protected], while an 80mm provides 2513N. This non-magnetic SKU cannot support switches. Note that standard cushions only decelerate; they do not hold loads on air loss. For that, use an external pilot check valve or the SAIL lock variant. The 160mm stroke is well within limits, but always guide rods to prevent side-load bending.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI63X160CA
- ✓ 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 SI63X160CA FAQ
Yes, the SI series is end-of-life. The direct replacement is the AirTAC SAI63X160CA. It is dimensionally interchangeable per ISO 15552, keeping the same 63mm bore, 160mm stroke, CA mount, and G3/8 port.
It features a G3/8 air port. Force output is 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.
