This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B06-SAUD50X125 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B06-SAUD50X125 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-SUD50X125
The AirTAC Airtac B06-SUD Battery Dedicated Standard Cylinder B06-SUD50X125 is a double-acting profile-type standard cylinder with a Ø50mm bore and 125mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the B06-SAUD50X125, which matches its bore, stroke, force and mounting.

About the Airtac B06-SUD Battery Dedicated Standard Cylinder B06-SUD50X125
The AirTAC B06-SUD50X125 is a double-acting, double-rod profile cylinder where the B06- prefix designates it as a battery-manufacturing dedicated variant, mechanically identical to the standard SUD50X125. A rod exits both ends of the extruded aluminum barrel on a single piston, meaning both faces use the rod-side area and push/pull force is equal both ways (825 N @0.5 MPa). Because it is discontinued, the exact drop-in replacement is the SAUD50X125, which retains the 50mm bore, 125mm stroke, 1/4" port, and FA/LB mounting.
This compact profile body is shorter than an ISO 15552 cylinder of the same bore. The dual-rod design provides anti-rotation stability and allows the back rod to drive a second tool simultaneously. For sizing, the safe working load is roughly 495 N (about 60% of the 825 N @0.5 MPa figure), translating to a vertical lift capacity of approximately 42 kg with a 2:1 margin. Note that this non-magnetic SKU (-S omitted) cannot accept legacy CS1-B/DS1-B sensors, whereas the SAUD replacement uses current CMSG/DMSG/EMSG switches.

Theoretical Output Force (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 825 N |
| 0.7 MPa | 1374 N | — |

Where the Airtac B06-SUD Battery Dedicated Standard Cylinder B06-SUD50X125 Is Used
Battery Cell Stacking
Equal both-ways force precisely indexes prismatic battery cells during stacking, using the dual rods to prevent twisting during multi-layer module assembly.
Pack Handling Transfer
Drives synchronized pushers on both sides of a conveyor line to align battery packs without requiring a second cylinder, saving space in tight assembly cells.
Tab Welding Clamp
Provides stable, anti-rotation clamping for battery tab welding fixtures, ensuring the electrode maintains perfect alignment through the 125mm stroke.
Replacing the Airtac B06-SUD Battery Dedicated Standard Cylinder B06-SUD50X125 with the B06-SAUD50X125
To replace the discontinued B06-SUD50X125, select the SAUD50X125 drop-in equivalent, matching the 50mm bore, 125mm stroke, 1/4" port, and FA/LB mounting. Size both ways by checking neighboring bores (40mm or 63mm) against the equal both-ways force requirement (825 N @0.5 MPa). A double-rod cylinder is correct when you need anti-rotation resistance or must drive two tools from one piston. Since this SKU lacks the -S suffix, it cannot take sensors; upgrading to the SAUD requires CMSG/DMSG/EMSG switches instead of legacy CS1-B/DS1-B. For strokes >=300mm, verify side-load limits to prevent guide wear. The cylinder cannot hold a load on air loss; use an external rod lock for held battery loads.
Replacement checklist
- ✓ Same bore / stroke → B06-SAUD50X125
- ✓ 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-SUD50X125 FAQ
Yes, the B06-SUD50X125 is discontinued. The exact drop-in replacement is the SAUD50X125, which shares the same 50mm bore, 125mm stroke, equal both-ways force, 1/4" port, and FA/LB mounting. The B06- prefix simply marks this as AirTAC's battery-manufacturing dedicated variant, so the physical specs are identical to the base SUD50X125.
Because it is a double-rod cylinder, the force is equal both ways: 825 N @0.5 MPa, 1154 N @0.7 MPa, and 1484 N @0.9 MPa. The air port is 1/4" (PT thread). The safe working load is approximately 495 N, allowing a vertical lift of about 42 kg with a 2:1 safety margin. The air cushion only decelerates the piston near stroke end; it does not hold the load on air loss.
