This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B06-SAI32X250S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B06-SAI32X250S 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-SI32X250S
The AirTAC Airtac B06-SI Battery Dedicated ISO Standard Cylinder B06-SI32X250S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 250mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the B06-SAI32X250S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac B06-SI Battery Dedicated ISO Standard Cylinder B06-SI32X250S
The AirTAC B06-SI32X250S is a discontinued double-acting ISO 15552 profile cylinder. The B06- prefix marks it as a battery-manufacturing dedicated variant of the base SI32X250S, mechanically identical with a 32mm bore, 250mm stroke, G1/8 port, and 402N push force at 0.5MPa. AirTAC replaced this EOL unit with the SAI32X250S, a true drop-in sharing the same ISO 15552 mounting interface, output force, and accessories.
The SAI upgrade features a modernized piston seal with two Y-shaped one-way elements for low start-up pressure and extended life. For battery line upgrades, the SAI family introduces SAIL (air-released lock), SAIF (built-in 4M valve), and BSAI (clamp-lock) variants the SI lacked. The original -S magnet supports CS1-B/DS1-B switches, while the SAI uses current AirTAC sensors. Computed insight: safe working load is roughly 241N (60% of 402N), yielding a 20kg vertical lift capacity with a 2:1 margin.

Where the Airtac B06-SI Battery Dedicated ISO Standard Cylinder B06-SI32X250S Is Used
Cell Stacking Press
Applies the 402N push force at 0.5MPa for aligning and pressing lithium-ion prismatic cells during module stacking, utilizing the 250mm stroke for clearance.
Tab Feeding & Handling
Indexing battery tabs or separators along the production line, where the 30-800mm/s speed range and CS1-B/DS1-B magnet sensing ensure rapid, confirmable cycles.
Pack Transfer
Shifts battery packs between conveyors; the safe working load of 241N easily handles lighter sub-modules, while the ISO 15552 interface allows direct fixture swap to SAI.
Replacing the Airtac B06-SI Battery Dedicated ISO Standard Cylinder B06-SI32X250S with the B06-SAI32X250S
To replace the B06-SI32X250S, order the SAI32X250S. Verify the ISO 15552 mounting interface, 32mm bore, 250mm stroke, G1/8 port (PT/G/NPT thread options), and the -S magnet. Sizing context: the 32mm bore yields 402N push at 0.5MPa; stepping up to a 40mm bore provides 628N. At 250mm stroke, use guide rails to prevent rod bending and side-load damage. A plain cylinder drifts on air loss—the cushion only decelerates. For battery cell stacking or handling that must hold position, use the SAIL lock, BSAI clamp-lock, or an external pilot check valve. Rod material options include carbon steel, SUS420J2 (A), and SUS304 (B); Viton H seals raise the temperature range to 0-150C.
Replacement checklist
- ✓ Same ISO 15552 interface → B06-SAI32X250S
- ✓ 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-SI32X250S FAQ
Yes, the B06-SI32X250S (the battery-manufacturing dedicated variant of the SI32X250S) is discontinued. The exact drop-in replacement is the SAI32X250S. It is dimensionally interchangeable per ISO 15552, retaining the same 32mm bore, 250mm stroke, 402N force, G1/8 port, and mounting interface.
The 32mm bore features a G1/8 air port and M10x1.25 rod thread. Forces are: push 402N and pull 345N at 0.5MPa; push 563N at 0.7MPa; push 724N at 0.9MPa; with a theoretical max of 82kgf at 1.0MPa. Operating pressure is 0.15-1.0MPa, speed is 30-800mm/s, and it has a 27mm adjustable air cushion at both ends.
