This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X330TC, 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 SI100X330TC
The AirTAC Airtac SI100 Standard Cylinder SI100X330TC is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 330mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100X330TC, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100X330TC
The AirTAC SI100X330TC is a discontinued double-acting ISO 15552 profile cylinder with a 100 mm bore and 330 mm stroke. It delivers 3927 N push force at 0.5 MPa. AirTAC replaced this legacy unit with the SAI100X330TC, a direct upgrade retaining the exact ISO 15552 mounting interface, G1/2 port, and TC trunnion mount.
The SAI upgrade features a modernized piston seal with two Y-shaped one-way elements for low start-up pressure and extended life. For applications needing load holding, the SAI family introduces SAIL and BSAI lock variants absent in the SI line. Note this SKU lacks a magnet, so it cannot accept a 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 SI100X330TC Is Used
Heavy Material Transfer
Drives robust pallet stops and heavy workpiece diverters on high-capacity conveyor lines using its 3927 N push force at 0.5 MPa.
Pallet Positioning
Indexes loaded pallets via the TC trunnion mount, accommodating the 330 mm stroke while managing side loads with external guides.
Press Ejection
Actuates large ejection gates in stamping presses, relying on the adjustable 36 mm air cushions to decelerate the 25 mm rod at stroke ends.
Replacing the Airtac SI100 Standard Cylinder SI100X330TC with the SAI100X330TC
To replace the SI100X330TC, order the SAI100X330TC. Verify your ISO 15552 TC trunnion mounting hardware, the G1/2 air port, and the M20x1.5 rod thread. Because this unit lacks a magnet (-S), it cannot support position sensing; if switches are needed, select an SAI model with the S suffix for current AirTAC sensors. At 0.5 MPa it yields 3927 N push and 3681 N pull; neighboring bores offer 2513 N (Ø80) or 6136 N (Ø125). With a 330 mm stroke, use external guides to prevent rod bending and side-load wear. A plain cylinder drifts on air loss; for load holding, specify the SAIL lock variant or an external pilot check valve.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100X330TC
- ✓ 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 SI100X330TC FAQ
Yes, the AirTAC SI100X330TC is discontinued. The direct replacement is the SAI100X330TC. It shares the same ISO 15552 mounting interface, 100 mm bore, 330 mm stroke, output force, G1/2 port, and TC trunnion mount, fitting directly into existing fixtures.
The 100 mm bore cylinder features a G1/2 air port and a 25 mm piston rod. It generates 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, with a theoretical maximum of 801 kgf at 1.0 MPa.
