This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100AX10S, 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 SI100AX10S
The AirTAC Airtac SI100 Standard Cylinder SI100AX10S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 10mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100AX10S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100AX10S
The AirTAC SI100AX10S is a discontinued double-acting ISO 15552 profile cylinder featuring a 100mm bore and 10mm stroke. It delivers 3927 N push force at 0.5 MPa through a G1/2 port. The direct replacement is the SAI100AX10S, matching the exact ISO 15552 mounting interface, bore, stroke, output force, and port size for seamless fixture integration.
The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and extended life. This specific unit includes the SUS420J2 stainless steel rod (-A) and a piston magnet (-S) for legacy CS1-B/DS1-B sensors. Note that plain cylinders drift without live air; use the SAIL or BSAI lock variants for holding.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |

Where the Airtac SI100 Standard Cylinder SI100AX10S Is Used
Short-Stroke Clamping
Ideal for high-force clamping jigs requiring minimal travel to secure heavy steel plates during machining operations.
Press Fit Ejection
Provides robust 3927 N push force for ejecting dense components from tight press-fit dies over a 10mm displacement.
Heavy Duty Gating
Actuates heavy industrial bulkhead gates or diverter valves where a compact 10mm stroke and high thrust are mandatory.
Replacing the Airtac SI100 Standard Cylinder SI100AX10S with the SAI100AX10S
To replace the SI100AX10S, order the SAI100AX10S and verify the ISO 15552 mounting interface, G1/2 port, and M20x1.5 rod thread. Retain your existing mounting accessories and confirm the -S magnet for current AirTAC switches, plus the -A SUS420J2 rod. For sizing down, an 80mm bore yields 2513 N at 0.5 MPa; sizing up to 125mm provides 6136 N. Remember the air cushion only decelerates; it does not hold loads. If you need braking, explore the SAIL air-released lock or BSAI clamp-lock, or use an external pilot check valve. The 10mm stroke is very short, so side-load risks are minimal, but always ensure rigid guidance.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100AX10S
- ✓ 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 SI100AX10S FAQ
Yes, the SI100AX10S is discontinued. The direct replacement is the SAI100AX10S. It is dimensionally interchangeable per ISO 15552, matching the 100mm bore, 10mm stroke, G1/2 port, and mounting interface exactly.
At 0.5 MPa it pushes 3927 N and pulls 3681 N. At 0.7 MPa push is 5497 N, and at 0.9 MPa it is 7068 N. The theoretical max force is 801 kgf at 1.0 MPa. Operating speed ranges from 30-800 mm/s.
