This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B06-SAI32X125S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B06-SAI32X125S in place of this model. 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 B06-SI Battery Dedicated ISO Standard Cylinder B06-SI32X125S
The AirTAC Airtac B06-SI Battery Dedicated ISO Standard Cylinder B06-SI32X125S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 125mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the B06-SAI32X125S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac B06-SI Battery Dedicated ISO Standard Cylinder B06-SI32X125S
The AirTAC B06-SI32X125S is a discontinued double-acting ISO 15552 profile cylinder. The B06- prefix marks it as a battery-manufacturing dedicated variant of the SI32X125S, mechanically identical to the base model. Delivering 402 N push force at 0.5 MPa via a G1/8 port, it is replaced by the drop-in SAI32X125S, which shares the exact same interface, stroke, and mounting.
The SAI32X125S upgrade features an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and long life. It retains the CS1-B/DS1-B legacy sensor compatibility via the -S magnet. For battery line loads, the safe working load is about 241 N (roughly 60% of the 0.5 MPa push force), yielding a vertical lift capacity of 20 kg with a 2:1 margin.

Where the Airtac B06-SI Battery Dedicated ISO Standard Cylinder B06-SI32X125S Is Used
Cell Stacking
Aligns and stacks prismatic battery cells with 241 N safe working force, ensuring gentle contact during module assembly.
Tab Handling
Positions cell tabs for laser welding on the production line, using the 125 mm stroke to feed materials accurately.
Pack Sorting
Diverts and sorts battery packs on conveyors, providing reliable 20 kg vertical lift with a 2:1 safety margin.
Replacing the Airtac B06-SI Battery Dedicated ISO Standard Cylinder B06-SI32X125S with the B06-SAI32X125S
To replace the B06-SI32X125S, order the SAI32X125S. Confirm the ISO 15552 mounting interface, 32 mm bore, 125 mm stroke, G1/8 port (PT/G/NPT thread options), and the -S magnet for CS1-B/DS1-B switches. Sizing both ways: the 402 N push at 0.5 MPa handles light battery cell handling, while stepping up to a 40 mm bore yields 628 N. Note that a plain cylinder drifts on air loss; for load holding, use an external pilot check valve or the SAIL/BSAI lock variants. At 125 mm stroke, guide rods are recommended to prevent side-load bending.
Replacement checklist
- ✓ Same ISO 15552 interface → B06-SAI32X125S
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac B06-SI Battery Dedicated ISO Standard Cylinder B06-SI32X125S FAQ
Yes, the B06-SI32X125S is discontinued. The exact drop-in replacement is the SAI32X125S. It is dimensionally interchangeable per ISO 15552, retaining the same 32 mm bore, 125 mm stroke, G1/8 port, and mounting interface. The B06- prefix simply denotes the battery-manufacturing dedicated variant, and the SAI family matches these physical specs exactly.
The 32 mm bore features a G1/8 air port and M10x1.25 rod thread. Force output is 402 N push and 345 N pull at 0.5 MPa, 563 N push at 0.7 MPa, 724 N push at 0.9 MPa, and a theoretical max of 82 kgf at 1.0 MPa. Operating speed is 30-800 mm/s.
