This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B06-SAUD50X25S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B06-SAUD50X25S 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-SUD50X25S
The AirTAC Airtac B06-SUD Battery Dedicated Standard Cylinder B06-SUD50X25S is a double-acting profile-type standard cylinder with a Ø50mm bore and 25mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the B06-SAUD50X25S, which matches its bore, stroke, force and mounting.

About the Airtac B06-SUD Battery Dedicated Standard Cylinder B06-SUD50X25S
The B06-SUD50X25S is a battery-manufacturing dedicated variant of the AirTAC SUD50X25S double-rod profile cylinder. The B06- prefix denotes an industry designation only; mechanically it is identical to the base SUD, featuring a 50mm bore, 25mm stroke, 1/4" port, and M16x1.5 rod thread. A rod exits both ends on a single piston, meaning push and pull force are equal both ways at 825N @0.5 MPa, 1154N @0.7 MPa, and 1484N @0.9 MPa. This SUD model is discontinued and the exact drop-in replacement is the SAUD50X25S.
Because both faces use the rod-side area, 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 (the SAUD replacement uses current CMSG/DMSG/EMSG sensors). The extruded aluminum profile barrel is shorter than an ISO 15552 cylinder of the same bore. For sizing, the computed safe working load is ~495N (about 60% of the 825N @0.5 figure), translating to a vertical lift capacity of ~42kg with a 2:1 margin. Note that the air cushion only decelerates near stroke end; an external rod lock is required for load holding.

Theoretical Output Force (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 825 N |
| 0.7 MPa | 1374 N | — |
| Max (@1.0 MPa) | 200 kgf | |
The B06-SAUD50X25S 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.
Where the Airtac B06-SUD Battery Dedicated Standard Cylinder B06-SUD50X25S Is Used
Cell Stacking Press
Applies equal both ways force for prismatic cell stacking and electrode alignment, using the back rod to carry a sensor cam for precise position feedback.
Module Transfer Handling
Drives dual-tool pick-and-place heads on battery module assembly lines, leveraging anti-rotation stability to prevent part misalignment during transit.
Pack Case Sealing
Performs synchronized clamping and sealing on battery pack housings, maintaining consistent pressure with its compact profile barrel and 1/4" port.
Replacing the Airtac B06-SUD Battery Dedicated Standard Cylinder B06-SUD50X25S with the B06-SAUD50X25S
To replace the discontinued B06-SUD50X25S, use the SAUD50X25S drop-in, which preserves the 50mm bore, 25mm stroke, 1/4" port, and FA/LB mounting compatibility with the AirTAC SC series. When sizing both ways, verify the equal-both-ways force fits your needs: the 50mm bore yields 825N @0.5, while the neighboring 40mm bore yields 528N and the 63mm yields 1402N. A double rod is right when you need anti-rotation stability or want to drive two tools simultaneously. If your unit has the -S magnet, upgrade sensors from legacy CS1-B/DS1-B to CMSG/DMSG/EMSG. For strokes >=300, confirm the side-load line to prevent guide wear. Never rely on the cushion for load holding without live air; add an external rod lock.
Replacement checklist
- ✓ Same bore / stroke → B06-SAUD50X25S
- ✓ 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-SUD50X25S FAQ
Yes, the B06-SUD50X25S is discontinued. The B06- prefix marks this as the battery-manufacturing dedicated variant of the base SUD50X25S, mechanically identical in bore, stroke, and force. The exact drop-in replacement is the SAUD50X25S, which keeps the same 50mm bore, 25mm stroke, 1/4" port, and FA/LB mounting.
Because it is a double-acting double-rod cylinder, force is equal both ways: 825N @0.5 MPa, 1154N @0.7 MPa, and 1484N @0.9 MPa. The bore dictates a fixed 1/4" air port. The safe working load is ~495N (60% of the 825N figure), allowing a vertical lift of ~42kg with a 2:1 margin.
