This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100BX80SH, 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 SI100BX80SH
The AirTAC Airtac SI100 Standard Cylinder SI100BX80SH is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 80mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100BX80SH, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100BX80SH
The AirTAC SI100BX80SH is a discontinued double-acting ISO 15552 profile cylinder with an 80 mm stroke and a SUS304 stainless steel rod. It delivers 3927 N push force at 0.5 MPa through its G1/2 port. The direct replacement is the SAI100BX80SH, which shares the exact ISO 15552 mounting interface, bore, stroke, and force.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. It also adds SAIL, SAIF, and BSAI variants the SI lacked. The Viton H seal option extends temperature range to 0-150 C.

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 SAI100BX80SH 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 SI100BX80SH Is Used
Stainless Rod Clamping
Leverages the SUS304 rod and 3927 N force to secure heavy metal parts in humid machining environments without surface corrosion.
High-Force Pallet Stops
Uses the 80 mm stroke and 5497 N push at 0.7 MPa to halt heavy loaded pallets reliably on conveyor lines.
High-Temperature Actuation
Takes advantage of the Viton H seal option (0-150 C) to operate heavy doors near ovens or thermal processing equipment.
Replacing the Airtac SI100 Standard Cylinder SI100BX80SH with the SAI100BX80SH
To replace this SI100BX80SH, order the SAI100BX80SH. Confirm the ISO 15552 mounting interface, the 80 mm stroke, the G1/2 port, and the SUS304 stainless rod. The built-in magnet works with legacy CS1-B/DS1-B switches, though the SAI uses current AirTAC sensors. For sizing, a 100 mm bore yields 3927 N push at 0.5 MPa; dropping to an 80 mm bore gives 2513 N, while a 125 mm bore provides 6136 N. Note that a plain cylinder drifts on air loss—the cushion only decelerates. For load holding, use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100BX80SH
- ✓ 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 SI100BX80SH FAQ
Yes, the SI100BX80SH is discontinued. The direct replacement is the SAI100BX80SH. It shares the same ISO 15552 mounting interface, 100 mm bore, 80 mm stroke, G1/2 port, and output force, fitting existing fixtures perfectly.
The G1/2 port bore delivers 3927 N push and 3681 N pull at 0.5 MPa, 5497 N push at 0.7 MPa, and 7068 N push at 0.9 MPa. The theoretical maximum force is 801 kgf at 1.0 MPa.
