This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B06-SAI40X350 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B06-SAI40X350 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.
The AirTAC Airtac B06-SI Battery Dedicated ISO Standard Cylinder B06-SI40X350 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø40mm bore and 350mm stroke, G1/4 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the B06-SAI40X350, which matches its ISO interface, bore, stroke, force and mounting.
The AirTAC B06-SI40X350 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 SI40X350, delivering 628 N push force at 0.5 MPa through a G1/4 port. AirTAC replaced this EOL unit with the SAI40X350.
The SAI40X350 is a true drop-in replacement, matching the exact ISO 15552 mounting interface, 350 mm stroke, and force. The upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure. For sizing, a safe working load is roughly 377 N (about 60% of the 628 N push force), equating to a 32 kg vertical lift with a 2:1 margin.

The B06-SAI40X350 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.

Legacy SI-family variants: SID (double rod), SIJ (adjustable stroke) — each maps to its SAI equivalent (SID→SAID, SIJ→SAIJ). Rod material: carbon steel (blank) / SUS420J2 (A) / SUS304 (B).
Applies the 628 N push force at 0.5 MPa to align and press lithium-ion battery cells during module stacking, utilizing the 350 mm stroke for deep fixture travel.
Transfers battery modules along the assembly line, where the G1/4 port and 30-800 mm/s speed provide rapid, controlled actuation between production stations.
Secures battery tabs during ultrasonic welding; the 32 kg vertical lift capacity with a 2:1 margin ensures stable clamping without deflecting the 16 mm rod.
To replace the B06-SI40X350, order the SAI40X350 and confirm the ISO 15552 mounting interface, 40 mm bore, 350 mm stroke, G1/4 port, and mounting accessory. This SKU lacks the -S magnet, so it cannot accept a sensor; if sensing is needed, specify an SAI with -S. For sizing, neighbouring bores are 32 mm (402 N push) and 50 mm (982 N push). A plain cylinder drifts on air loss, so for load holding use the SAIL lock, BSAI clamp-lock, or an external pilot check valve. Because the 350 mm stroke exceeds 300 mm, use an external guide to prevent rod bending and side loads. The SAI family also offers the SAIF variant with a built-in 4M valve.
Replacement checklist
Yes, the B06-SI40X350 (battery-manufacturing dedicated SI40X350) is discontinued. The exact drop-in replacement is the SAI40X350. It shares the identical ISO 15552 mounting interface, 40 mm bore, 350 mm stroke, output force, and G1/4 port, fitting existing fixtures perfectly.
The bore is 40 mm with a G1/4 port. 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. The rod thread is M12x1.25.
