This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X1500SLB, 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 SI100X1500SLB
The AirTAC SI100 Standard Cylinder SI100X1500SLB is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 1500mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100X1500SLB, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100X1500SLB
The AirTAC SI100X1500SLB is a discontinued double-acting ISO 15552 profile cylinder with a 100mm bore and 1500mm stroke. Delivering 3927N push force at 0.5MPa, it is replaced by the SAI100X1500SLB. This direct upgrade keeps the same G1/2 port, M20x1.5 thread, and LB foot mount interface.
The SAI replacement features an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure. The original -S magnet supports CS1-B/DS1-B sensors, while the SAI family adds SAIL lock and BSAI clamp-lock variants.

Where the Airtac SI100 Standard Cylinder SI100X1500SLB Is Used
Long-Stroke Material Pusher
Drives heavy workpieces across a 1.5m conveyor transfer station, utilizing the 3927N thrust at 0.5MPa to shift pallets without stalling.
High-Level Storage Actuator
Extends 1500mm to reach top-tier automated storage racks, relying on the LB foot mount and external guides to handle the extended rod length safely.
Pallet Diversion Gate
Cycles continuously to redirect heavy packaging lines, with the adjustable 36mm air cushions decelerating the load at both ends of the long stroke.
Replacing the Airtac SI100 Standard Cylinder SI100X1500SLB with the SAI100X1500SLB
To replace the SI100X1500SLB, order the SAI100X1500SLB. Confirm the ISO 15552 LB foot mount, 100mm bore, 1500mm stroke, G1/2 port, and -S magnet for current AirTAC switches. Sizing both ways: a neighboring 80mm bore yields 2513N push at 0.5MPa, while a 125mm bore yields 6136N. For load holding, note a plain cylinder drifts on air loss as cushions only decelerate; use an external rod lock, pilot check valve, or SAIL/BSAI variant. At 1500mm stroke, use external guides to prevent rod bending from side loads. Rod options include carbon steel, SUS420J2, or SUS304.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100X1500SLB
- ✓ 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 SI100X1500SLB FAQ
Yes, the SI100X1500SLB is discontinued. The direct replacement is the SAI100X1500SLB. It is dimensionally interchangeable per ISO 15552, retaining the same 100mm bore, 1500mm stroke, G1/2 port, LB foot mount, and force ratings.
The 100mm bore features a G1/2 port and M20x1.5 rod thread. Force output is 3927N push and 3681N pull at 0.5MPa, 5497N push at 0.7MPa, 7068N push at 0.9MPa, and a theoretical max of 801kgf at 1.0MPa.
