This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X600TC, 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 SI100X600TC
The AirTAC Airtac SI100 Standard Cylinder SI100X600TC is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 600mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100X600TC, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100X600TC
The AirTAC SI100X600TC is a discontinued double-acting ISO 15552 profile cylinder with a 100 mm bore and 600 mm stroke. It delivers 3927 N push force at 0.5 MPa via a G1/2 port. Because this legacy unit lacks a magnet (-S), it cannot accept position sensors.
You must replace it with the SAI100X600TC. This direct retains the exact TC trunnion mount, M20x1.5 rod thread, and 36 mm cushions. The SAI upgrades the piston seal to two Y-shaped one-way elements for lower start-up pressure.

Where the Airtac SI100 Standard Cylinder SI100X600TC Is Used
Heavy Material Transfer
Drives large pallets or heavy workpieces along extended conveyor sections, utilizing the 3927 N push force to overcome high sliding friction over the 600 mm travel.
Automated Warehousing
Actuates large-scale lifting or routing gates in distribution centers where the TC trunnion mount absorbs pivotal stresses during long-stroke package diversion.
Large Assembly Press
Provides the steady clamping pressure required to seat heavy automotive or industrial components, relying on the 36 mm adjustable cushions to stop the 100 mm bore smoothly.
Replacing the Airtac SI100 Standard Cylinder SI100X600TC with the SAI100X600TC
To replace the SI100X600TC, order the SAI100X600TC to keep the identical ISO 15552 TC trunnion mounting interface, 100 mm bore, 600 mm stroke, and G1/2 port. Verify your thread option (PT, G, or NPT). Since this specific SKU has no magnet, it cannot support sensing; if you need switches, select an SAI equivalent with the S suffix for current AirTAC sensors. When sizing, note the 801 kgf maximum at 1.0 MPa, or step down to an 80 mm bore (513 kgf max) if lower force is acceptable. For the 600 mm stroke, use an external guide to prevent rod bending and side-load damage. Remember that standard cushions only decelerate the load; they do not hold it. For static holding on air loss, use an external pilot check valve or the SAIL/BSAI lock variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100X600TC
- ✓ 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 SI100X600TC FAQ
Yes, the AirTAC SI100X600TC is discontinued. The direct replacement is the SAI100X600TC. It is dimensionally interchangeable per ISO 15552, matching the exact bore, stroke, TC mounting, G1/2 port, and force ratings, so it fits existing fixtures directly.
This 100 mm bore cylinder uses a G1/2 air port. The thrust is 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 of 801 kgf at 1.0 MPa.
