This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X600SLB, 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 SI100X600SLB
The AirTAC Airtac SI100 Standard Cylinder SI100X600SLB 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 SAI100X600SLB, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100X600SLB
The AirTAC SI100X600SLB is a discontinued double-acting ISO 15552 profile cylinder with a 100mm bore and 600mm stroke. It delivers 3927N push force at 0.5MPa via a G1/2 port. AirTAC replaced this legacy unit with the SAI100X600SLB, a direct sharing the exact ISO 15552 mounting interface, bore, stroke, output force, and LB foot mount.
The SAI upgrade features a modernized piston seal with two Y-shaped one-way elements for low start-up pressure and extended life. The SAI family also introduces SAIL, SAIF, and BSAI lock variants absent in the SI line.

Where the Airtac SI100 Standard Cylinder SI100X600SLB Is Used
Heavy Material Transfer
Drives robust pallet stops and heavy workpiece diverters on high-throughput conveyor lines requiring substantial 3927N push force.
Automated Warehousing
Actuates large lifting gates and heavy-load positioning carriages in automated storage and retrieval systems over a 600mm travel.
Industrial Pressing
Provides steady clamping and pressing pressure for heavy-duty assembly jigs and large component machining fixtures.
Replacing the Airtac SI100 Standard Cylinder SI100X600SLB with the SAI100X600SLB
To replace the SI100X600SLB, order the SAI100X600SLB. Verify the ISO 15552 interface, 100mm bore, 600mm stroke, G1/2 port, and LB foot mounting accessory. The -S suffix indicates a piston magnet for legacy CS1-B/DS1-B sensors; the SAI replacement uses current AirTAC switches. If sizing up or down, neighboring bores (80mm or 125mm) alter the 0.5MPa push force (2513N or 6136N). Because this is a 600mm stroke, use an external guide to prevent rod bending and side-load wear. A plain cylinder drifts without air; for load holding, use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100X600SLB
- ✓ 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 SI100X600SLB FAQ
Yes, the AirTAC SI100X600SLB is discontinued. The direct replacement is the SAI100X600SLB. It is dimensionally interchangeable per ISO 15552, retaining the same 100mm bore, 600mm stroke, G1/2 port, and LB foot mount.
At 0.5MPa it provides 3927N push and 3681N pull force. At 0.7MPa push is 5497N, and at 0.9MPa it is 7068N. The theoretical max force is 801kgf at 1.0MPa. Operating pressure is 0.15-1.0MPa, speed is 30-800mm/s, and it uses a G1/2 port.
