This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B06-SAUD40X400S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B06-SAUD40X400S 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-SUD40X400S
The AirTAC Airtac B06-SUD Battery Dedicated Standard Cylinder B06-SUD40X400S is a double-acting profile-type standard cylinder with a Ø40mm bore and 400mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the B06-SAUD40X400S, which matches its bore, stroke, force and mounting.

About the Airtac B06-SUD Battery Dedicated Standard Cylinder B06-SUD40X400S
The AirTAC B06-SUD40X400S is a double-acting profile cylinder where the B06- prefix marks it as a battery-manufacturing dedicated variant of the base SUD40X400S, mechanically identical in every spec. A rod exits both ends on one piston, meaning both faces use the rod-side area and push/pull force is equal at 528N @0.5, 739N @0.7 and 950N @0.9 MPa. The extruded aluminium profile barrel is shorter than an ISO 15552 cylinder of the same 40mm bore. This SUD model is discontinued and the exact drop-in replacement is the SAUD40X400S, retaining the 1/4" port, M12x1.25 rod thread and 21mm cushions.
For battery line integration, the double-rod design offers anti-rotation stability and allows the back rod to carry a sensor cam for CS1-B/DS1-B switches. The SAUD upgrade switches to current CMSG/DMSG/EMSG sensors. Based on the 528N @0.5 MPa force, the safe working load is approximately 317N, yielding a vertical lift capacity of about 27kg with a 2:1 margin. Note that a plain cylinder does not hold loads on air loss; the air cushion only decelerates near stroke end, so an external rod lock is required for held loads.

Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |

Where the Airtac B06-SUD Battery Dedicated Standard Cylinder B06-SUD40X400S Is Used
Cell Stacking Assembly
Drives precision stacking plates in prismatic cell assembly, utilising the equal both ways force to compress electrode layers consistently without rotational drift.
Module Tab Welding
Actuates dual-side welding heads simultaneously using both extending rods, ensuring balanced pressure on battery module busbars during ultrasonic welding.
Pack Handling Transfer
Transfers battery packs between conveyor lines on the manufacturing floor, where the 400mm stroke accommodates extended indexing distances across the production cell.
Replacing the Airtac B06-SUD Battery Dedicated Standard Cylinder B06-SUD40X400S with the B06-SAUD40X400S
To replace the discontinued B06-SUD40X400S, specify the drop-in SAUD40X400S which matches the 40mm bore, 400mm stroke, 1/4" port, and FA/LB mounting. Size both ways by checking neighbour bores while ensuring the equal-both-ways force (528N @0.5 MPa) meets your requirement. Choose a double-rod cylinder when you need anti-rotation stability or need to drive two tools simultaneously. Because the -S suffix denotes a piston magnet, plan a sensor change from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG. For this 400mm stroke, provide external guides to prevent rod bending and manage side loads.
Replacement checklist
- ✓ Same bore / stroke → B06-SAUD40X400S
- ✓ 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-SUD40X400S FAQ
Yes, the B06-SUD40X400S is discontinued. The B06- prefix simply marks it as the battery-manufacturing dedicated variant of the base SUD40X400S. The exact drop-in replacement is the SAUD40X400S, which shares identical bore, stroke, 1/4" port, and force, but upgrades the sensors to CMSG/DMSG/EMSG.
Because it is a double-rod cylinder, the push and pull force are equal both ways: 528N @0.5 MPa, 739N @0.7 MPa, and 950N @0.9 MPa. The fixed air port size for the 40mm bore is 1/4". The safe working load is approximately 317N at 0.5 MPa.
