This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B06-SAI40X800S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B06-SAI40X800S 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-SI40X800S
The AirTAC Airtac B06-SI Battery Dedicated ISO Standard Cylinder B06-SI40X800S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø40mm bore and 800mm stroke, G1/4 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the B06-SAI40X800S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac B06-SI Battery Dedicated ISO Standard Cylinder B06-SI40X800S
The AirTAC B06-SI40X800S is a discontinued double-acting ISO 15552 profile cylinder. The B06- prefix marks it as a battery-manufacturing dedicated variant of the SI40X800S, engineered for cell stacking and pack assembly lines. Mechanically identical to the base model, it delivers 628 N push force at 0.5 MPa through a 40 mm bore and 800 mm stroke.
AirTAC replaced this legacy unit with the SAI40X800S drop-in replacement. The SAI retains the exact ISO 15552 mounting interface, G1/4 port, and M12x1.25 rod thread, but introduces an upgraded piston seal with two Y-shaped one-way elements for lower start-up pressure and longer life. For your sizing, the safe working load is roughly 377 N (about 60% of the 628 N push force), translating to a vertical lift capacity of approximately 32 kg with a 2:1 margin. If your battery line requires positive load holding on air loss, explore the SAIL or BSAI lock variants, as standard cushions only decelerate.

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-SAI40X800S 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-SI40X800S Is Used
Cell Stacking Press
Drives the extended 800 mm stacking stroke for prismatic battery cells, providing consistent 628 N clamping force during electrode alignment.
Module Transfer
Actuates long-travel pushers on battery module assembly conveyors, moving heavy packs between welding stations with smooth cushioning.
Pack Handling
Depalletizes or indexes battery packs along the 800 mm stroke, utilizing the magnetic piston for end-of-stroke position confirmation.
Replacing the Airtac B06-SI Battery Dedicated ISO Standard Cylinder B06-SI40X800S with the B06-SAI40X800S
To replace the B06-SI40X800S, order the SAI40X800S. Confirm your ISO 15552 mounting accessory (LB foot, FA flange, TC trunnion), the G1/4 air port, and the -S magnet for CS1-B/DS1-B legacy sensors. The SAI family also adds SAIF (built-in 4M valve) and SAIL (air-released lock) options the SI lacked. For sizing alternatives: a 32 mm bore yields 402 N push at 0.5 MPa, while a 50 mm bore yields 982 N. At 800 mm stroke, prevent rod bending and premature seal wear by guiding the load externally to absorb side-load forces. Remember, a plain cylinder drifts without live air; use a pilot check valve or BSAI clamp-lock for static holding.
Replacement checklist
- ✓ Same ISO 15552 interface → B06-SAI40X800S
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
