This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B06-SAUD40X250S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B06-SAUD40X250S 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.
Airtac B06-SUD Battery Dedicated Standard Cylinder B06-SUD40X250S
The AirTAC Airtac B06-SUD Battery Dedicated Standard Cylinder B06-SUD40X250S is a double-acting profile-type standard cylinder with a Ø40mm bore and 250mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the B06-SAUD40X250S, which matches its bore, stroke, force and mounting.

About the Airtac B06-SUD Battery Dedicated Standard Cylinder B06-SUD40X250S
The AirTAC B06-SUD40X250S is a double-acting double-rod profile cylinder where the B06- prefix marks it as a battery-manufacturing dedicated variant of the base SUD40X250S, mechanically identical to it. A rod exits both ends on a single piston, meaning both faces use the rod-side area and push/pull force is equal at 528 N @0.5 MPa, 739 N @0.7 MPa, and 950 N @0.9 MPa. The extruded aluminium profile barrel is shorter than an ISO 15552 cylinder of the same bore. This legacy model is discontinued; the exact drop-in replacement is the SAUD40X250S, retaining the 40mm bore, 250mm stroke, 1/4" port, and FA/LB mounting.
Because the rear rod can carry a sensor cam or drive a second tool simultaneously, double-rod designs excel in anti-rotation and compact multi-tool tasks. The bore dictates a 16mm rod, M12x1.25 thread, and 21mm adjustable cushions at each end. For sizing, a safe working load is roughly 317 N (about 60% of the 528 N @0.5 MPa figure), translating to a vertical lift capacity of about 27 kg with a 2:1 margin. Note that the air cushion only decelerates near stroke end; an external rod lock is required for load holding on air loss. The -S suffix indicates a piston magnet for legacy CS1-B/DS1-B switches, which the SAUD upgrades to CMSG/DMSG/EMSG sensors.

Where the Airtac B06-SUD Battery Dedicated Standard Cylinder B06-SUD40X250S Is Used
Battery Cell Stacking
Equal both-ways force drives precision cell stacking and tabbing mechanisms in battery module assembly, utilizing the rear rod for cam-actuated sensor feedback.
Pack Handling Transfer
Anti-rotation dual-end drive moves battery packs between conveyor belts without torsional deflection, maintaining alignment during high-speed indexing.
Dual-Tool Actuation
Simultaneously drives a forming tool on the front rod and a clamping mechanism on the rear rod, optimizing compact battery-pack production line footprint.
Replacing the Airtac B06-SUD Battery Dedicated Standard Cylinder B06-SUD40X250S with the B06-SAUD40X250S
To replace the discontinued B06-SUD40X250S, specify the SAUD40X250S drop-in: it matches the 40mm bore, 250mm stroke, 1/4" port, M12x1.25 rod thread, and FA/LB mounting. When sizing, verify equal both-ways force across neighbouring bores (32mm yields 345 N @0.5 MPa; 50mm yields 825 N @0.5 MPa) to ensure your application fits the 528 N @0.5 MPa capacity of this 40mm unit. A double-rod cylinder is right when you need anti-rotation, a back rod to carry a sensor cam, or to drive two tools. The -S suffix means you must change legacy CS1-B/DS1-B switches to CMSG/DMSG/EMSG sensors on the SAUD. For this 250mm stroke (which is >=300mm), carefully check side-load alignment to prevent guide bushing wear. Mounting is compatible with AirTAC SC series accessories only.
Replacement checklist
- ✓ Same bore / stroke → B06-SAUD40X250S
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S): sensor family CS1-B → CMSG
- ✓ Mounting reused (FA/FB/CA/CB/LB)
- ✓ Need a built-in valve? → SAUF
Airtac B06-SUD Battery Dedicated Standard Cylinder B06-SUD40X250S FAQ
Yes, the B06-SUD40X250S is discontinued. The B06- prefix marks it as a battery-manufacturing dedicated variant of the base SUD40X250S, mechanically identical to it. The exact drop-in replacement is the SAUD40X250S, which matches the 40mm bore, 250mm stroke, 1/4" port, and FA/LB mounting. You must upgrade the -S piston magnet switches from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG sensors.
Because it is a double-rod cylinder, force is equal both ways: 528 N @0.5 MPa, 739 N @0.7 MPa, and 950 N @0.9 MPa. The 40mm bore dictates a 1/4" port (default PT thread), a 16mm rod, an M12x1.25 rod-end thread, and 21mm adjustable cushions at each end. The safe working load is roughly 317 N (about 60% of the 528 N @0.5 MPa figure), allowing a vertical lift of about 27 kg with a 2:1 margin.
