This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B06-SAI32X250 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B06-SAI32X250 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-SI32X250
The AirTAC Airtac B06-SI Battery Dedicated ISO Standard Cylinder B06-SI32X250 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-SAI32X250, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac B06-SI Battery Dedicated ISO Standard Cylinder B06-SI32X250
The AirTAC B06-SI32X250 is a discontinued double-acting ISO 15552 profile cylinder. The B06- prefix marks it as a battery-manufacturing dedicated variant, mechanically identical to the standard SI32X250. It delivers 402 N push force at 0.5 MPa through a 32 mm bore, 250 mm stroke, and G1/8 port. As this SKU lacks the -S magnet, it cannot accept a position sensor.
AirTAC replaced the SI line with the SAI32X250. This drop-in upgrade retains the exact ISO 15552 mounting interface, output force, and cushioning, but adds an upgraded piston seal (two Y-shaped one-way elements for low start-up pressure). For battery line upgrades needing load holding, the SAI family introduces SAIL and BSAI lock variants. A practical computed insight: the safe working load is roughly 241 N (about 60% of the 402 N push force), equating to a 20 kg vertical lift with a 2:1 safety margin.

Specifications follow the official AirTAC SI datasheet (now discontinued). The B06-SAI32X250 carries the same ISO 15552 ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 kgf | |
The B06-SAI32X250 produces the same force from the same bore — a true drop-in on output. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac B06-SI Battery Dedicated ISO Standard Cylinder B06-SI32X250 Is Used
Cell Stacking Press
Applies the 402 N push force for aligning and pressing prismatic cells during module stacking, utilizing the 250 mm stroke to accommodate varying cell thicknesses.
Tab Handling & Sorting
Moves battery tabs and interconnect foils along the assembly conveyor, where the 30-800 mm/s speed range ensures rapid cycling without damaging delicate components.
Pack Diverting
Acts as a diverter arm on battery pack assembly lines, using the 20 kg safe vertical lift capacity to reorient or reject battery modules during quality control checks.
Replacing the Airtac B06-SI Battery Dedicated ISO Standard Cylinder B06-SI32X250 with the B06-SAI32X250
To replace the B06-SI32X250, order the SAI32X250. Confirm the ISO 15552 mounting interface, 32 mm bore, 250 mm stroke, G1/8 port, and M10x1.25 rod thread. Because this is a no-S SKU, it cannot take a sensor; if position feedback is needed on the new line, specify the SAI with an -S magnet for current AirTAC switches. Sizing both ways: the 32 mm bore gives 402 N push at 0.5 MPa, while the neighbouring 40 mm bore yields 628 N. For a 250 mm stroke, ensure guiding to prevent rod bending under side loads. A plain cylinder drifts on air loss; for battery stacking or handling that must hold position, use an external pilot check valve or the SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → B06-SAI32X250
- ✓ 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-SI32X250 FAQ
Yes, the B06-SI32X250 (battery-manufacturing dedicated SI32X250) is discontinued. The exact drop-in replacement is the SAI32X250. It is dimensionally interchangeable per ISO 15552, matching the 32 mm bore, 250 mm stroke, 402 N force, G1/8 port, and mounting accessories.
The 32 mm bore features a G1/8 port and M10x1.25 rod thread. At 0.5 MPa it provides 402 N push and 345 N pull force. At 0.7 MPa push is 563 N, and 724 N at 0.9 MPa. The theoretical maximum force is 82 kgf at 1.0 MPa. Operating speed is 30-800 mm/s.
