This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B06-SAUD50X400S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B06-SAUD50X400S 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-SUD50X400S
The AirTAC Airtac B06-SUD Battery Dedicated Standard Cylinder B06-SUD50X400S is a double-acting profile-type standard cylinder with a Ø50mm bore and 400mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the B06-SAUD50X400S, which matches its bore, stroke, force and mounting.

About the Airtac B06-SUD Battery Dedicated Standard Cylinder B06-SUD50X400S
The AirTAC B06-SUD50X400S is a discontinued double-acting, double-rod profile cylinder where the B06- prefix marks it as a battery-manufacturing dedicated variant of the base SUD50X400S, mechanically identical to it. A rod exits both ends on one piston, meaning both faces use the rod-side area and push/pull force is equal both ways at 825 N @0.5 MPa, 1154 N @0.7 MPa, and 1484 N @0.9 MPa. The extruded aluminum profile barrel is shorter than an ISO 15552 cylinder of the same 50 mm bore. This unit features a 1/4" port, M16x1.5 rod thread, and a 400 mm stroke.
As this SUD model is end-of-life, the exact drop-in replacement is the SAUD50X400S, which matches the bore, stroke, equal force, port, and FA/LB mounting. 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, though the SAUD replacement upgrades to current CMSG/DMSG/EMSG sensors. For sizing, the 825 N @0.5 MPa force yields a safe working load of 495 N and a vertical lift capacity of roughly 42 kg with a 2:1 margin. Note that air cushions only decelerate 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-SAUD50X400S 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-SUD50X400S Is Used
Battery Cell Stacking
Equal push and pull force drives precise cell stacking and alignment mechanisms in battery module assembly without rotational drift.
Pack Handling Transfer
The dual-rod design drives two synchronized tools to transfer battery packs smoothly along the production line, ensuring parallel movement.
Tab Welding Positioning
The rear rod carries a sensor cam for legacy CS1-B/DS1-B switches to confirm position during automated battery tab welding operations.
Replacing the Airtac B06-SUD Battery Dedicated Standard Cylinder B06-SUD50X400S with the B06-SAUD50X400S
To replace the discontinued B06-SUD50X400S, drop in the SAUD50X400S, which preserves the 50 mm bore, 400 mm stroke, 1/4" port, and equal-both-ways force. Size both ways by checking neighbor bores to ensure the 825 N @0.5 MPa output fits your application, keeping in mind the double-rod architecture is right when you need anti-rotation or dual-tool driving. Mounting is limited to Basic, FA, and LB styles (SC-series compatible). Because this has an -S magnet, plan a sensor change from legacy CS1-B/DS1-B to CMSG/DMSG/EMSG. For this 400 mm stroke, external guides are recommended to manage side-load and rod-bending forces.
Replacement checklist
- ✓ Same bore / stroke → B06-SAUD50X400S
- ✓ 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-SUD50X400S FAQ
Yes, it is discontinued. The B06- prefix marks it as the battery-manufacturing dedicated variant of the base SUD50X400S, mechanically identical to it. The exact drop-in replacement is the SAUD50X400S, which matches the bore, stroke, force, and 1/4" port, but upgrades the -S magnet sensors from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG.
Because it is a double-rod cylinder, force is equal both ways: 825 N @0.5 MPa, 1154 N @0.7 MPa, and 1484 N @0.9 MPa. The safe working load is 495 N. The bore is 50 mm with a 1/4" port, M16x1.5 rod thread, and a 400 mm stroke. Air cushions only decelerate; use an external rod lock for load holding.
