This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B06-SAUD40X300S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B06-SAUD40X300S 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-SUD40X300S
The AirTAC Airtac B06-SUD Battery Dedicated Standard Cylinder B06-SUD40X300S is a double-acting profile-type standard cylinder with a Ø40mm bore and 300mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the B06-SAUD40X300S, which matches its bore, stroke, force and mounting.

About the Airtac B06-SUD Battery Dedicated Standard Cylinder B06-SUD40X300S
The AirTAC B06-SUD40X300S is a double-acting, double-rod profile cylinder where the B06- prefix marks it as a battery-manufacturing dedicated variant, mechanically identical to the standard SUD40X300S. A rod exits both ends on one piston, meaning both faces use the rod-side area and push/pull force is equal both ways (528 N at 0.5 MPa). The extruded aluminium profile barrel is shorter than an ISO 15552 cylinder of the same 40 mm bore. This SUD model is discontinued and the exact drop-in replacement is the SAUD40X300S, which retains the 1/4" port, M12x1.25 rod thread, and FA/LB mounting.
Because the rear rod can carry a sensor cam or drive a second tool simultaneously, double-rod designs excel in anti-rotation and compact synchronous handling tasks. The built-in piston magnet works with legacy CS1-B/DS1-B switches, whereas the SAUD replacement uses current CMSG/DMSG/EMSG sensors. For sizing, the 528 N force at 0.5 MPa yields a safe working load of roughly 317 N (about 60%), translating to a vertical lift capacity of approximately 27 kg with a 2:1 margin. Note that air cushions only decelerate near stroke end; an external rod lock is required to hold loads safely on air loss.

Where the Airtac B06-SUD Battery Dedicated Standard Cylinder B06-SUD40X300S Is Used
Battery Cell Stacking
Equal both ways force ensures precise, anti-rotation pressure when stacking and aligning delicate battery cells during module assembly.
Tabbing & Handling
The rear rod drives a secondary mechanism or sensor cam, synchronizing tab welding and pack handling without adding extra valves.
Pack Transfer
Compact 40 mm profile barrel fits tight battery line conveyors, providing stable push and pull transfer of battery packs.
Replacing the Airtac B06-SUD Battery Dedicated Standard Cylinder B06-SUD40X300S with the B06-SAUD40X300S
To replace the discontinued B06-SUD40X300S, drop in the SAUD40X300S, which matches the 40 mm bore, 300 mm stroke, 1/4" port, and FA/LB mounting exactly. When sizing both ways, verify your force requirements against the equal both ways ratings (528 N at 0.5 MPa, 739 N at 0.7 MPa, 950 N at 0.9 MPa) and check neighbouring bores if you need higher capacity. A double rod is the right choice when you need anti-rotation stability or want to drive two tools from one piston. Because this unit has the -S magnet, you must upgrade your legacy CS1-B/DS1-B sensors to CMSG/DMSG/EMSG models for the SAUD. With the 300 mm stroke, ensure external guides are used to prevent rod bending and manage side loads effectively.
Replacement checklist
- ✓ Same bore / stroke → B06-SAUD40X300S
- ✓ 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-SUD40X300S FAQ
Yes, the B06-SUD40X300S is discontinued. The exact drop-in replacement is the SAUD40X300S. The B06- prefix simply marks it as a battery-manufacturing dedicated variant, so the SAUD matches the 40 mm bore, 300 mm stroke, 1/4" port, and FA/LB mounting exactly. You only need to upgrade the sensors from CS1-B/DS1-B to CMSG/DMSG/EMSG.
Because it is a double-rod cylinder, force is equal both ways: 528 N at 0.5 MPa, 739 N at 0.7 MPa, and 950 N at 0.9 MPa. The 40 mm bore uses a 1/4" port (default PT thread) and a 16 mm rod with an M12x1.25 thread. The safe working load at 0.5 MPa is approximately 317 N, allowing a vertical lift of about 27 kg with a 2:1 margin.
