This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X100SCA, 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 SI100X100SCA
The AirTAC Airtac SI100 Standard Cylinder SI100X100SCA is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 100mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100X100SCA, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100X100SCA
The AirTAC SI100X100SCA is a discontinued double-acting ISO 15552 profile cylinder with a 100mm bore and 100mm stroke. It delivers 3927 N push force at 0.5 MPa through a G1/2 port. AirTAC replaced this legacy unit with the SAI100X100SCA, a direct sharing the exact same ISO 15552 mounting interface, CA clevis mount, output force and stroke.
The SAI upgrade features a revised piston seal using two Y-shaped one-way elements for lower start-up pressure and longer life. The SAI family also introduces SAIL, SAIF and BSAI lock variants absent in the SI line. This -S unit supports CS1-B/DS1-B sensors.

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 SI100X100SCA Is Used
Heavy Press Clamping
Secures large metal castings in machining centers, utilizing the 3927 N push force to hold components firmly against cutting loads.
Pallet Diverting
Actuates heavy-duty routing gates on high-throughput packaging lines, easily handling pallet weights up to the 200 kg vertical lift capacity.
Automated Guided Vehicle Lifting
Drives the main vertical mast elevation on AGVs, moving goods between floor level and conveyor heights with stable CA clevis articulation.
Replacing the Airtac SI100 Standard Cylinder SI100X100SCA with the SAI100X100SCA
To replace the SI100X100SCA, order the SAI100X100SCA. Verify your ISO 15552 interface, 100mm bore, 100mm stroke, G1/2 port threads (PT/G/NPT) and the CA clevis mounting accessory. Because the -S magnet is present, plan to upgrade your legacy CS1-B/DS1-B switches to current AirTAC sensors. Sizing both ways: a neighbouring 80mm bore yields 2513 N push at 0.5 MPa, while a 125mm bore yields 6136 N. Note that a plain cylinder drifts without live air; the cushion only decelerates. For load holding, specify the SAIL lock, BSAI clamp-lock, or an external pilot check valve. Rod material options include carbon steel, SUS420J2 (A) or SUS304 (B).
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100X100SCA
- ✓ 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 SI100X100SCA FAQ
Yes, the SI100X100SCA is discontinued. The direct replacement is the SAI100X100SCA. It is dimensionally interchangeable per ISO 15552, matching the 100mm bore, 100mm stroke, G1/2 port, CA mount and output force, so it fits existing fixtures directly.
This 100mm bore cylinder uses a G1/2 port. It generates 3927 N push and 3681 N pull at 0.5 MPa, 5497 N push at 0.7 MPa, 7068 N push at 0.9 MPa, and a theoretical maximum force of 801 kgf at 1.0 MPa. Operating speed is 30-800 mm/s.
