This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B06-SAI40X25S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B06-SAI40X25S 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-SI40X25S
The AirTAC Airtac B06-SI Battery Dedicated ISO Standard Cylinder B06-SI40X25S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø40mm bore and 25mm stroke, G1/4 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the B06-SAI40X25S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac B06-SI Battery Dedicated ISO Standard Cylinder B06-SI40X25S
The AirTAC B06-SI40X25S is a discontinued double-acting ISO 15552 profile cylinder delivering 628 N push force at 0.5 MPa. The B06- prefix marks it as a battery-manufacturing dedicated variant, mechanically identical to the base SI40X25S with a 25 mm stroke, G1/4 port, and M12x1.25 rod thread. AirTAC replaced this legacy line with the SAI40X25S, a true drop-in upgrade sharing the exact ISO 15552 mounting interface, bore, and output force.
The SAI replacement introduces an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and long life. For battery line integration, the safe working load is roughly 377 N (about 60% of the 628 N push force), yielding a vertical lift capacity of approximately 32 kg with a 2:1 margin. The original SI-S magnet supports legacy CS1-B/DS1-B sensors, while the SAI family adds SAIL, SAIF, and BSAI lock or valve variants absent in the SI line.

Where the Airtac B06-SI Battery Dedicated ISO Standard Cylinder B06-SI40X25S Is Used
Battery Cell Stacking
Ideal for short 25 mm positioning strokes in battery cell stacking modules, providing 628 N push force to align cells accurately without overshooting.
Tab Welding Clamp
Used in battery tab welding stations where a 32 kg vertical lift capacity and precise end-of-stroke cushioning ensure consistent electrical contact.
Module Handling Stop
Serves as a compact stopper on battery module assembly conveyors, leveraging the ISO 15552 profile barrel for easy sensor bracket mounting.
Replacing the Airtac B06-SI Battery Dedicated ISO Standard Cylinder B06-SI40X25S with the B06-SAI40X25S
To replace the B06-SI40X25S, order the SAI40X25S, confirming the ISO 15552 mounting interface, 40 mm bore, 25 mm stroke, G1/4 port (PT/G/NPT), and the -S magnet for current AirTAC switches. If downsizing from a 50 mm bore, note the 50 mm offers 982 N push at 0.5 MPa versus this 40 mm bore's 628 N; if upsizing from 32 mm (402 N), the 40 mm provides a noticeable force increase without changing the 30-800 mm/s speed range. The cushion only decelerates the piston; it does not hold load on air loss, so for vertical battery-cell stacking use an external pilot check valve or the SAIL/BSAI lock variant. Standard rod material is carbon steel, with SUS420J2 (A) or SUS304 (B) options available.
Replacement checklist
- ✓ Same ISO 15552 interface → B06-SAI40X25S
- ✓ 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-SI40X25S FAQ
Yes, the B06-SI40X25S is discontinued. The exact drop-in replacement is the SAI40X25S. It features the same ISO 15552 mounting interface, 40 mm bore, 25 mm stroke, 628 N force, and G1/4 port. The B06- prefix simply denotes the battery-manufacturing dedicated variant, and the SAI upgrade is mechanically identical.
The bore is 40 mm with a G1/4 air port and M12x1.25 rod thread. Force ratings are: 628 N push and 528 N pull at 0.5 MPa, 879 N push at 0.7 MPa, 1130 N push at 0.9 MPa, and a theoretical max of 128 kgf at 1.0 MPa. It operates at 30-800 mm/s.
