This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B06-SAUD50X250S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B06-SAUD50X250S 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-SUD50X250S
The AirTAC Airtac B06-SUD Battery Dedicated Standard Cylinder B06-SUD50X250S is a double-acting profile-type standard cylinder with a Ø50mm bore and 250mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the B06-SAUD50X250S, which matches its bore, stroke, force and mounting.

About the Airtac B06-SUD Battery Dedicated Standard Cylinder B06-SUD50X250S
The B06-SUD50X250S is a double-acting, double-rod profile cylinder where the leading B06- prefix designates it as AirTAC's battery-manufacturing dedicated variant of the base SUD50X250S, mechanically identical in every spec. Because a rod exits both ends on one piston, both faces use the rod-side area, making push and pull force equal at 825 N @0.5 MPa, 1154 N @0.7 MPa, and 1484 N @0.9 MPa. The extruded aluminium profile barrel is shorter than an ISO 15552 cylinder of the same 50 mm bore. It features a 1/4 inch port, M16x1.5 rod thread, and 21 mm adjustable air cushions at each end. This legacy model is discontinued.
The exact drop-in replacement is the SAUD50X250S, which matches the 50 mm bore, 250 mm stroke, equal-both-ways force, 1/4 inch port, and FA/LB mounting. The double-rod design provides anti-rotation stability and allows the back rod to carry a sensor cam, while the front rod drives a tool. With a magnet for position sensing, this SUD used CS1-B/DS1-B switches, whereas the SAUD uses current CMSG/DMSG/EMSG sensors. For sizing, the safe working load is roughly 495 N (60% of the 825 N @0.5 MPa figure), and the vertical lift capacity is about 42 kg with a 2:1 margin. Note that a plain cylinder does not hold loads on air loss; the cushion only decelerates near stroke end, so use an external rod lock for held loads.

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-SUD50X250S Is Used
Battery Cell Stacking
Aligns and pushes prismatic battery cells into modules with equal push and pull force, using the double-rod anti-rotation property to maintain precise electrode stacking.
Module Transfer Handling
Transfers battery modules along an assembly line where the front rod drives a gripper and the back rod carries a sensor cam for dual-tool synchronized motion.
Tab Welding Press
Applies consistent clamping pressure for battery tab welding, utilizing the equal both ways 825 N @0.5 MPa force to ensure uniform contact across the cell pack.
Replacing the Airtac B06-SUD Battery Dedicated Standard Cylinder B06-SUD50X250S with the B06-SAUD50X250S
To replace the discontinued B06-SUD50X250S, use the SAUD50X250S drop-in, which matches the 50 mm bore, 250 mm stroke, 1/4 inch port, and equal-both-ways force. If adjusting force, size both ways using neighbouring bores: the 40 mm bore yields 528/739/950 N, and the 63 mm bore yields 1402/1962/2523 N. A double rod is right when you need anti-rotation stability or want the back rod to carry a sensor cam. Mounting is Basic, FA, or LB only (SC-series compatibility). The -S suffix means a magnet is present; you must change legacy CS1-B/DS1-B switches to CMSG/DMSG/EMSG sensors for the SAUD. For stroke lengths >=300 mm, verify side-load limits to prevent guide wear.
Replacement checklist
- ✓ Same bore / stroke → B06-SAUD50X250S
- ✓ 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-SUD50X250S FAQ
Yes, the B06-SUD50X250S is discontinued. The B06- prefix marks it as the battery-manufacturing dedicated variant of the base SUD50X250S. The exact drop-in replacement is the SAUD50X250S, which shares the same 50 mm bore, 250 mm stroke, 1/4 inch port, and FA/LB mounting.
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 operating speed is 30-800 mm/s. It operates at 0.15-1.0 MPa with a 1/4 inch port and M16x1.5 rod thread.
