This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B06-SAUD50X300S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B06-SAUD50X300S 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.

The AirTAC Airtac B06-SUD Battery Dedicated Standard Cylinder B06-SUD50X300S is a double-acting profile-type standard cylinder with a Ø50mm bore and 300mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the B06-SAUD50X300S, which matches its bore, stroke, force and mounting.
The AirTAC B06-SUD50X300S is a double-acting, double-rod profile cylinder where the B06- prefix designates it as a battery-manufacturing dedicated variant of the base SUD50X300S, mechanically identical to it. A rod exits both ends of the extruded aluminium barrel on a single 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 bore is 50 mm, port is 1/4", and rod thread is M16x1.5. This legacy model is discontinued and the direct drop-in replacement is the SAUD50X300S.
Because the rear rod can carry a sensor cam or drive a second tool simultaneously, double-rod designs excel in anti-rotation tasks. With a 0.5 MPa operating pressure, the computed safe working load is roughly 495 N (about 60% of the 825 N figure), allowing a vertical lift of approximately 42 kg with a 2:1 margin. Note that the air cushion only decelerates near stroke end; an external rod lock is required for load holding. The SAUD upgrade retains the exact FA/LB mounting but uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches found on this unit.

The B06-SAUD50X300S 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.

Legacy SU-family variants: SUD (double rod), SUJ (adjustable stroke) — each maps to its SAU equivalent (SUD→SAUD, SUJ→SAUJ). The current SAU line adds the SAUF valve-integrated option.
Synchronises dual pressing plates during lithium-ion cell stacking, utilising the equal both-ways force to maintain precise, anti-rotation alignment throughout the 300 mm travel.
Drives a dual-ended pusher mechanism on a battery module assembly conveyor, using the second rod to mount a sensor cam for exact position feedback without adding external brackets.
Applies equal clamping pressure during battery pack tab welding, ensuring the electrode maintains consistent contact while the opposing rod manages wire management.
To replace the discontinued B06-SUD50X300S, drop in the SAUD50X300S, which matches the 50 mm bore, 300 mm stroke, 1/4" port, and equal-both-ways force. When sizing both ways, verify if neighbouring bores (like 40 mm or 63 mm) fit your force envelope, but this 50 mm bore delivers 825 N @0.5 MPa equally in both directions. Choose a double-rod cylinder when you need anti-rotation stability or need to drive two tools from one piston. Mounting is limited to Basic, FA, and LB styles (SC-series compatible only). Since this unit has the -S magnet, you must upgrade from CS1-B/DS1-B sensors to CMSG/DMSG/EMSG on the SAUD. For this 300 mm stroke, external guides are recommended to prevent rod bending under side loads.
Replacement checklist
Yes, the B06-SUD50X300S is discontinued. The exact drop-in replacement is the SAUD50X300S. The B06- prefix simply marks it as a battery-manufacturing dedicated variant, so the SAUD matches the 50 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, the force is equal both ways: 825 N @0.5 MPa, 1154 N @0.7 MPa, and 1484 N @0.9 MPa. The bore is 50 mm, the air port is 1/4", and the rod thread is M16x1.5. The computed safe working load is 495 N, allowing a vertical lift of about 42 kg with a 2:1 margin.
