This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B06-SAUD40X25 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B06-SAUD40X25 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-SUD40X25
The AirTAC Airtac B06-SUD Battery Dedicated Standard Cylinder B06-SUD40X25 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-SAUD40X25, which matches its bore, stroke, force and mounting.

About the Airtac B06-SUD Battery Dedicated Standard Cylinder B06-SUD40X25
The AirTAC B06-SUD40X25 is a double-acting, double-rod profile cylinder where the battery-manufacturing dedicated B06- prefix denotes a unit mechanically identical to the standard SUD40X25 for cell and pack assembly lines. A rod exits both ends of the extruded aluminum barrel on a single piston, meaning push and pull forces are equal both ways at 528 N @0.5 MPa, 739 N @0.7 MPa, and 950 N @0.9 MPa. This model is discontinued and the exact drop-in replacement is the SAUD40X25, which retains the 40mm bore, 25mm stroke, 1/4" port, and FA/LB mounting.
Because both faces use the rod-side area, the second rod provides anti-rotation stability and can drive a second tool simultaneously. For sizing, the safe working load is approximately 317 N (60% of the 528 N @0.5 figure), yielding a vertical lift capacity of about 27 kg with a 2:1 margin. Note this non-magnetic SKU cannot take a sensor, and the air cushion only decelerates near stroke end—it does not hold loads on air loss.

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-SAUD40X25 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-SUD40X25 Is Used
Cell Stacking Alignment
Uses the equal both-ways force and anti-rotation properties to precisely press and align prismatic battery cells during stacking operations.
Module Transfer Handling
Drives a dual-gripper transfer mechanism on the battery module assembly line, utilizing the second rod to carry a cam or secondary tool.
Tab Welding Clamp
Provides stable, equal clamping pressure on both extension and retraction for battery tab welding fixtures within compact machinery.
Replacing the Airtac B06-SUD Battery Dedicated Standard Cylinder B06-SUD40X25 with the B06-SAUD40X25
To replace the discontinued B06-SUD40X25, specify the SAUD40X25 drop-in: it matches the 40mm bore, 25mm stroke, 1/4" port, M12x1.25 rod thread, and FA/LB mounting. Size both directions by checking the equal-both-ways force (528 N @0.5); if more push is needed, step up to the 50mm bore, or step down to 32mm for lighter loads. Choose a double-rod cylinder when you need anti-rotation stability or must drive two tools from one body. Since this SKU lacks a magnet, you cannot mount switches; if sensing is required, move to the SAUD-S variant and change from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG sensors. For any stroke over 300mm, verify side-load limits to prevent guide wear.
Replacement checklist
- ✓ Same bore / stroke → B06-SAUD40X25
- ✓ 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-SUD40X25 FAQ
Yes, this battery-manufacturing dedicated double-rod cylinder is discontinued. The exact drop-in replacement is the SAUD40X25, which shares the same 40mm bore, 25mm stroke, 1/4" port, and equal force. The B06- prefix only denotes the industry application and changes no physical specs.
Force is equal both ways at 528 N @0.5 MPa, 739 N @0.7 MPa, and 950 N @0.9 MPa. This specific SKU is non-magnetic and cannot accept a sensor switch. The air cushion only decelerates the piston near stroke end; it does not hold the load on air loss, so an external rod lock is required for held loads.
