This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X163SN, 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 SI100 Standard Cylinder SI100X163SN
The AirTAC SI100 Standard Cylinder SI100X163SN is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 163mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100X163SN, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100X163SN
The AirTAC SI100X163SN is a discontinued double-acting ISO 15552 profile cylinder featuring a 100mm bore and 163mm stroke, delivering a push force of 3927 N at 0.5 MPa. It is directly replaced by the SAI100X163SN, a direct upgrade retaining the exact same ISO 15552 mounting interface, G1/2 port, and 801 kgf maximum force. The SAI family introduces an upgraded piston seal with two Y-shaped one-way elements for lower start-up pressure and longer life.
This legacy unit includes a piston magnet for CS1-B/DS1-B switches and an NBR seal (-N) rated for -20 to +70 C (a Viton H option extends this to 150 C). Note that a standard cylinder drifts without live air; for held loads, explore the SAIL or BSAI lock variants.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAI100X163SN carries the same ISO 15552 ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |
| Max (@1.0 MPa) | 801 kgf | |
The SAI100X163SN produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac SI100 Standard Cylinder SI100X163SN Is Used
Heavy-Duty Pressing
Applies the 5497 N push force at 0.7 MPa to seat bearings and assemble heavy mechanical components securely.
Material Diversion
Actuates large diverter arms on high-throughput packaging lines using the 163mm stroke and robust 25mm rod.
Replacing the Airtac SI100 Standard Cylinder SI100X163SN with the SAI100X163SN
To replace the discontinued SI100X163SN, order the SAI100X163SN direct equivalent, verifying the ISO 15552 mounting interface, 100mm bore, 163mm stroke, G1/2 port, and your specific mounting accessory. The -S magnet enables legacy CS1-B/DS1-B sensors, while the SAI uses current AirTAC switches. If downsizing, the 80mm bore yields 2513 N push at 0.5 MPa; if upsizing, the 125mm bore provides 6136 N. Remember that air cushions only decelerate the load near stroke end and do not hold position on air loss—use an external pilot check valve or the SAIL/BSAI lock variants for secure holding. The standard 30-800 mm/s speed range and M20x1.5 rod thread apply.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100X163SN
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SI100 Standard Cylinder SI100X163SN FAQ
Yes, the SI100X163SN is discontinued. The direct replacement is the SAI100X163SN, which shares the identical ISO 15552 mounting interface, 100mm bore, 163mm stroke, force, and G1/2 port for a seamless fixture swap.
This 100mm bore cylinder features a G1/2 air port and delivers 3927 N push / 3681 N pull at 0.5 MPa, 5497 N push at 0.7 MPa, and a theoretical maximum of 801 kgf at 1.0 MPa.
