This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B06-SAUD40X25S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B06-SAUD40X25S in place of this model. The SAU replacement uses the same profile body, bore, stroke, force and SC-series mounting. It moves to the current CMSG / DMSG / EMSG sensor switches (the SU used CS1-B / DS1-B) and adds the SAUF valve-integrated option.

The AirTAC Airtac B06-SUD Battery Dedicated Standard Cylinder B06-SUD40X25S is a double-acting profile-type standard cylinder with a Ø40mm bore and 25mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the B06-SAUD40X25S, which matches its bore, stroke, force and mounting.
The AirTAC B06-SUD40X25S is a discontinued double-rod profile cylinder where the B06- prefix marks it as a battery-manufacturing dedicated variant of the base SUD40X25S. Mechanically identical to the base model, it features a 40mm bore, 25mm stroke, and a rod exiting both ends on a single piston, ensuring push and pull force are equal at 528N @0.5 MPa. The extruded aluminium profile barrel is notably shorter than an ISO 15552 cylinder of the same bore. It uses a 1/4 inch port and M12x1.25 rod thread.
As this SUD series is end-of-life, the exact drop-in replacement is the SAUD40X25S, retaining the same bore, stroke, force, port, and FA/LB mounting. The double-rod design provides anti-rotation stability and allows the back rod to carry a sensor cam for legacy CS1-B/DS1-B switches. For sizing, the safe working load is approximately 317N (about 60% of the 528N @0.5 MPa figure), translating to a vertical lift capacity of roughly 27kg with a 2:1 margin.

The B06-SAUD40X25S 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 SU-family variants: SUD (double rod), SUJ (adjustable stroke) — each maps to its SAU equivalent (SUD→SAUD, SUJ→SAUJ). The current SAU line adds the SAUF valve-integrated option.
Ideal for prismatic cell stacking and alignment in battery module assembly, utilizing the equal both ways force to push and pull electrodes precisely without rotational drift.
Drives dual-sided transfer arms on conveyor lines for battery pack handling, where the double-rod design allows a rear cam to trigger sensors while the front rod moves the payload.
Provides stable, anti-rotation clamping for battery tab welding fixtures, ensuring the M12x1.25 rod end holds the tooling rigidly during the welding cycle.
To replace this discontinued cylinder, specify the SAUD40X25S, which is a direct drop-in retaining the 40mm bore, 25mm stroke, 1/4 inch port, and FA/LB mounting compatibility with the AirTAC SC series. Because force is equal both ways, you can size both directions using the 528N @0.5 MPa figure; if higher force is needed, step up to the 50mm bore (825N) or down to the 32mm bore (345N). A double-rod configuration is the right choice when you need anti-rotation stability or want to drive two tools simultaneously. If your unit has the -S magnet option, note that the SAU replacement uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches. For this 25mm stroke, side-load alignment is minimal, but for any stroke over 300mm, carefully support the rod to prevent binding.
Replacement checklist
Yes, the B06-SUD40X25S (a battery-manufacturing dedicated variant of the SUD40X25S) is discontinued. The exact drop-in replacement is the SAUD40X25S, which shares the same 40mm bore, 25mm stroke, 1/4 inch port, and equal-both-ways force. The SAUD also offers the SAUF built-in-valve variant the SU line lacked.
The 40mm bore double-rod design ensures force is equal both ways: 528N @0.5 MPa, 739N @0.7 MPa, and 950N @0.9 MPa. The air port is 1/4 inch. Note that a plain cylinder does not hold loads on air loss; the 21mm adjustable cushion only decelerates near stroke end, so use an external rod lock for held loads.
