This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B06-SAI40X400 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B06-SAI40X400 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-SI40X400
The AirTAC Airtac B06-SI Battery Dedicated ISO Standard Cylinder B06-SI40X400 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø40mm bore and 400mm stroke, G1/4 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the B06-SAI40X400, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac B06-SI Battery Dedicated ISO Standard Cylinder B06-SI40X400
The AirTAC B06-SI40X400 is a discontinued double-acting ISO 15552 profile cylinder. The B06- prefix marks it as a battery-manufacturing dedicated variant, though mechanically it is identical to the base SI40X400, delivering 628 N push force at 0.5 MPa through a 40 mm bore and 400 mm stroke.
You must replace it with the drop-in SAI40X400. This current-production ISO 15552 cylinder retains the exact G1/4 port, M12x1.25 thread, and mounting interface. The SAI upgrades the piston seal to two Y-shaped one-way elements for low start-up pressure. For sensing, note this no-S SKU cannot take a magnetic switch. A safe working load is roughly 377 N (about 32 kg vertical lift).

Specifications follow the official AirTAC SI datasheet (now discontinued). The B06-SAI40X400 carries the same ISO 15552 ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
The B06-SAI40X400 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-SI40X400 Is Used
Cell Stacking Assembly
Drives stacking mechanisms in prismatic cell assembly lines, utilizing the 400 mm stroke to index separator and electrode materials with precise positioning.
Module Transfer Handling
Moves battery modules between welding and testing stations on conveyor belts, providing reliable 628 N push force for automated pack routing.
Tab Welding Clamping
Actuates clamping fixtures during busbar and cell tab welding operations, ensuring rigid holding during the ultrasonic or laser joining process.
Replacing the Airtac B06-SI Battery Dedicated ISO Standard Cylinder B06-SI40X400 with the B06-SAI40X400
To replace this B06-SI40X400, order the SAI40X400. It drops into existing fixtures via the identical ISO 15552 mounting interface, matching the 40 mm bore, 400 mm stroke, 628 N push force at 0.5 MPa, and G1/4 port. If you need to size up, the 50 mm bore yields 982 N push at 0.5 MPa; sizing down, the 32 mm bore provides 402 N. Because this is a 400 mm stroke, use an external guide to prevent rod-bending side loads. This non-magnet SKU cannot accept a sensor. For battery line load-holding without live air, use the SAIL lock or BSAI clamp-lock variant, as cushions only decelerate.
Replacement checklist
- ✓ Same ISO 15552 interface → B06-SAI40X400
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
