This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B06-SAUD40X125 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B06-SAUD40X125 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-SUD40X125
The AirTAC Airtac B06-SUD Battery Dedicated Standard Cylinder B06-SUD40X125 is a double-acting profile-type standard cylinder with a Ø40mm bore and 125mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the B06-SAUD40X125, which matches its bore, stroke, force and mounting.

About the Airtac B06-SUD Battery Dedicated Standard Cylinder B06-SUD40X125
The AirTAC B06-SUD40X125 is a discontinued double-acting double-rod profile cylinder. The B06- prefix marks it as a battery-manufacturing dedicated variant of the base SUD40X125, mechanically identical with a 40mm bore, 125mm stroke, 1/4" port, and M12x1.25 rod thread. Because a rod exits both ends on one piston, push and pull force are equal both ways (528N at 0.5MPa). The exact drop-in replacement is the SAUD40X125, which retains the same profile body, bore, force, and FA/LB mounting.
A key double-rod benefit is anti-rotation, allowing the back rod to drive a second tool simultaneously. The compact extruded aluminum barrel is shorter than an ISO 15552 cylinder. Based on the 528N force at 0.5MPa, the safe working load is roughly 317N, yielding a vertical lift capacity of about 27kg with a 2:1 margin. Note this SKU lacks a magnet (-S) so it cannot take a sensor; the SAUD upgrade uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B.

Specifications follow the official AirTAC SU datasheet (now discontinued). The B06-SAUD40X125 carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
The B06-SAUD40X125 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.

Where the Airtac B06-SUD Battery Dedicated Standard Cylinder B06-SUD40X125 Is Used
Battery Cell Stacking
Equal both ways force precisely presses and separates battery cell layers during automated stacking operations.
Module Transfer Handling
The anti-rotation double-rod design securely pushes battery modules along conveyor lines without twisting.
Pack Tabbing Press
Drives two opposing tabbing tools simultaneously from one piston for balanced, compact pack assembly.
Replacing the Airtac B06-SUD Battery Dedicated Standard Cylinder B06-SUD40X125 with the B06-SAUD40X125
To replace the discontinued B06-SUD40X125, specify the SAUD40X125 drop-in. Size both ways by checking neighbor bores (32mm or 50mm) to ensure the equal-both-ways force fits your system. Choose a double-rod cylinder when you need anti-rotation or must drive two tools from one piston. Mounting is limited to Basic, FA, and LB (SC-series compatible only). For sensing, note this SKU has no magnet, while the SAUD supports CMSG/DMSG/EMSG sensors. For strokes >=300mm, verify side-load limits to prevent guide wear. A plain cylinder does not hold loads on air loss; the cushion only decelerates, so use an external rod lock for held loads.
Replacement checklist
- ✓ Same bore / stroke → B06-SAUD40X125
- ✓ 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-SUD40X125 FAQ
Yes, the B06-SUD40X125 (battery-manufacturing dedicated SUD40X125) is discontinued. The exact drop-in replacement is the SAUD40X125, which matches the 40mm bore, 125mm stroke, 1/4" port, and equal both ways force.
Because it is a double-rod cylinder, force is equal both ways: 528N at 0.5MPa, 739N at 0.7MPa, and 950N at 0.9MPa. The bore is 40mm with a 1/4" port. This yields a safe working load of about 317N and a vertical lift of roughly 27kg.
