This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X150TC, 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 SI100X150TC
The AirTAC Airtac SI100 Standard Cylinder SI100X150TC is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 150mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100X150TC, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100X150TC
The AirTAC SI100X150TC is a discontinued double-acting ISO 15552 profile cylinder with a 100mm bore and 150mm stroke. It delivers 3927 N push force at 0.5 MPa via a G1/2 port. AirTAC replaced this legacy unit with the SAI100X150TC, a direct upgrade retaining the exact TC trunnion mount, M20x1.5 rod thread, and 36mm cushions.
The SAI replacement features an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and extended life. Note this non-magnet SKU cannot accept a CS1-B/DS1-B sensor.

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 SI100X150TC Is Used
Heavy Press Clamping
Secures large automotive castings during machining operations, utilizing the 3927 N push force at 0.5 MPa to prevent workpiece shifting under high spindle loads.
Pallet Diverting
Actuates heavy-duty routing gates on 150mm strokes to redirect loaded pallets, relying on the TC trunnion mount to absorb angular side-stresses during transit.
Replacing the Airtac SI100 Standard Cylinder SI100X150TC with the SAI100X150TC
To replace the SI100X150TC, order the SAI100X150TC. Verify the ISO 15552 TC trunnion interface, 150mm stroke, G1/2 port (PT/G/NPT thread options), and M20x1.5 rod. Since this SKU lacks the -S magnet, it cannot hold a position sensor; order an -S variant if switch tracking is needed. Sizing both ways: the neighbouring 80mm bore yields 2513 N push @0.5 MPa, while the 125mm bore offers 6136 N. This plain cylinder does not hold load without live air; the cushions only decelerate. For load holding on air loss, use an external pilot check valve or explore the SAIL (air-released lock) or BSAI (clamp-lock) variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100X150TC
- ✓ 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 SI100X150TC FAQ
Yes, the AirTAC SI100X150TC is discontinued. The direct replacement is the SAI100X150TC. It is dimensionally interchangeable per ISO 15552, retaining the same 100mm bore, 150mm stroke, G1/2 port, TC trunnion mount, and output force for existing fixtures.
This double-acting cylinder uses a G1/2 air port. The thrust ratings are: 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.
