This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B06-SAI40X500S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B06-SAI40X500S 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-SI40X500S
The AirTAC Airtac B06-SI Battery Dedicated ISO Standard Cylinder B06-SI40X500S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø40mm bore and 500mm stroke, G1/4 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the B06-SAI40X500S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac B06-SI Battery Dedicated ISO Standard Cylinder B06-SI40X500S
The B06-SI40X500S is a discontinued double-acting ISO 15552 profile cylinder optimized for battery manufacturing. The B06- prefix designates this as a battery-dedicated variant of the SI40X500S, mechanically identical to the standard model. It delivers 628 N push force at 0.5 MPa through a 40 mm bore and 500 mm stroke. AirTAC replaced this EOL unit with the SAI40X500S.
The SAI40X500S is a true drop-in replacement sharing the exact ISO 15552 mounting interface, G1/4 port, and M12x1.25 rod thread. It features an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and long life. For your sizing, the safe working load is roughly 377 N (60% of the 628 N push force), yielding a vertical lift capacity of about 32 kg with a 2:1 margin.

Where the Airtac B06-SI Battery Dedicated ISO Standard Cylinder B06-SI40X500S Is Used
Cell Stacking Press
Drives the 500 mm stacking stroke for lithium-ion prismatic cells, providing consistent 628 N pressure at 0.5 MPa during electrode assembly.
Module Transfer
Pushes battery modules along assembly conveyors with a safe working load of 377 N, utilizing the long stroke for packaging line transitions.
Tab Welding Clamp
Positions and holds battery tabs for laser welding, relying on adjustable air cushions to decelerate the rod smoothly at stroke ends.
Replacing the Airtac B06-SI Battery Dedicated ISO Standard Cylinder B06-SI40X500S with the B06-SAI40X500S
To replace the B06-SI40X500S, order the SAI40X500S and confirm the ISO 15552 mounting interface, G1/4 port, and the -S magnet for CS1-B/DS1-B legacy sensors (the SAI uses current AirTAC switches). For battery line tasks needing less force, a 32 mm bore provides 402 N push at 0.5 MPa; for heavier module handling, an 80 mm bore yields 2513 N. Note that a plain cylinder drifts on air loss—the cushion only decelerates—so use an external rod lock or pilot check valve for load holding, or specify the SAIL/BSAI lock variant. Because the 500 mm stroke invites rod bending, add external guides to manage side loads.
Replacement checklist
- ✓ Same ISO 15552 interface → B06-SAI40X500S
- ✓ 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-SI40X500S FAQ
Yes, the B06-SI40X500S (the battery-manufacturing dedicated variant of SI40X500S) is discontinued. The exact drop-in replacement is the SAI40X500S. It shares the same ISO 15552 mounting interface, 40 mm bore, 500 mm stroke, G1/4 port, and output force, fitting existing fixtures perfectly.
The 40 mm bore uses a G1/4 air port and an M12x1.25 rod thread. Force output is 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, with a theoretical max of 128 kgf at 1.0 MPa. Operating speed is 30-800 mm/s.
