This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B06-SAI40X300 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B06-SAI40X300 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-SI40X300 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø40mm bore and 300mm stroke, G1/4 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the B06-SAI40X300, which matches its ISO interface, bore, stroke, force and mounting.
The AirTAC B06-SI40X300 is a discontinued double-acting ISO 15552 profile cylinder. The B06- prefix marks this as a battery-manufacturing dedicated variant, though mechanically it is identical to the base SI40X300, delivering 628 N push force at 0.5 MPa through a 40 mm bore. AirTAC replaced this end-of-life unit with the SAI40X300, a true drop-in upgrade sharing the same interface, G1/4 port, and 300 mm stroke.
The SAI replacement features an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and extended life. Buyers gain a safe working load of roughly 377 N (about 60% of the 0.5 MPa push) or a 32 kg vertical lift with a 2:1 margin. Note this non-magnet SKU cannot accept a sensor; the SAI family also adds SAIL, SAIF, and BSAI lock variants the legacy SI lacked.

The B06-SAI40X300 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 cell layers during automated stacking operations.
Transfers battery modules along the assembly line, utilizing the 300 mm stroke to push packs between stations.
Holds battery tabs firmly in place for laser welding, relying on the adjustable 27 mm air cushions for smooth end-of-stroke deceleration.
To replace this discontinued cylinder, order the SAI40X300. Confirm it matches your ISO 15552 mounting fixtures, 40 mm bore, 300 mm stroke, G1/4 port, and M12x1.25 rod thread. Because this is a no-S SKU, it lacks a magnet and cannot support position sensing; if you need switches, select an SAI40X300S and use current AirTAC sensors instead of the legacy CS1-B/DS1-B. At 0.5 MPa the 40 mm bore yields 628 N push and 528 N pull; if you need less force, step down to a 32 mm bore (402 N push), or step up to a 50 mm bore (982 N push) for higher loads. For this 300 mm stroke, use an external guide to prevent rod bending and side-load wear. A plain cylinder drifts on air loss—the cushion only decelerates—so for load holding, specify the SAIL lock, BSAI clamp-lock, or an external pilot check valve.
Replacement checklist
Yes, the B06-SI40X300 is discontinued. The exact drop-in replacement is the SAI40X300. It is dimensionally interchangeable per ISO 15552, retaining the same 40 mm bore, 300 mm stroke, 628 N force, G1/4 port, and mounting interface. The B06- prefix simply designates it as a battery-manufacturing dedicated variant of the base SI40X300.
This 40 mm bore double-acting cylinder features a G1/4 air port. The thrust 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 maximum of 128 kgf at 1.0 MPa. It operates at 30-800 mm/s with a 16 mm rod and M12x1.25 thread.
