This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100BX160, 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 SI100BX160
The AirTAC Airtac SI100 Standard Cylinder SI100BX160 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 160mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100BX160, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100BX160
The AirTAC SI100BX160 is a discontinued double-acting ISO 15552 profile cylinder with a 100 mm bore and 160 mm stroke. Delivering 3927 N push and 3681 N pull at 0.5 MPa via a G1/2 port, it is superseded by the direct replacement SAI100BX160. This SUS304 stainless-rod (-B) variant resists corrosion, and because it lacks a -S magnet, it cannot accept a sensor. The SAI upgrade features two Y-shaped one-way piston seals for low start-up pressure.
The SAI family adds SAIL, SAIF and BSAI lock variants the SI lacked. If you need Viton H seals for 0-150 C heat, or legacy CS1-B sensors for a different magnetized SKU, confirm those attributes during replacement.

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 SAI100BX160 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 SI100BX160 Is Used
Heavy-Duty Pressing
Drives robust pressing and stamping operations, utilizing the 3927 N thrust at 0.5 MPa to seat bearings and form components reliably.
High-Force Diversion
Actuates heavy structural diverters and gates on high-throughput packaging lines, where the 25 mm rod handles substantial side-loading.
Replacing the Airtac SI100 Standard Cylinder SI100BX160 with the SAI100BX160
To replace the SI100BX160, order the SAI100BX160. It drops into existing fixtures using the same ISO 15552 mounting interface, 100 mm bore, 160 mm stroke, G1/2 port, and M20x1.5 rod thread. Because this specific SKU lacks a magnet (-S), it cannot support position sensing; if you require switches, select a magnetized SAI model and use current AirTAC sensors rather than the legacy CS1-B/DS1-B set. Sizing both ways: stepping down to an 80 mm bore lowers force to 2513 N push, while pushing pressure to 0.7 MPa on this 100 mm bore yields 5497 N. Note that a plain cylinder drifts without live air—the cushions only decelerate. For load holding on air loss, specify an external pilot check valve or the SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100BX160
- ✓ 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 SI100BX160 FAQ
Yes, the SI100BX160 is discontinued. The direct replacement is the AirTAC SAI100BX160. It shares the identical ISO 15552 mounting interface, 100 mm bore, 160 mm stroke, output force, and G1/2 port, fitting existing fixtures perfectly while upgrading the piston seal.
This double-acting cylinder features a G1/2 port and generates 3927 N push and 3681 N pull at 0.5 MPa. At 0.7 MPa push is 5497 N, at 0.9 MPa it is 7068 N, and the theoretical max is 801 kgf at 1.0 MPa. The SUS304 rod provides corrosion resistance.
