This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B06-SAUD50X125S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B06-SAUD50X125S 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-SUD50X125S 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-SAUD50X125S, which matches its bore, stroke, force and mounting.
The AirTAC B06-SUD50X125S is a discontinued double-acting profile cylinder where the B06- prefix designates it as a battery-manufacturing dedicated variant of the base SUD50X125S, mechanically identical to the standard model. A rod exits both ends 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 extruded aluminium profile barrel is shorter than an ISO 15552 cylinder of the same bore. This bore features a 1/4" port, an M16x1.5 rod thread, and a 21 mm adjustable air cushion at each end. As this SUD model is end-of-life, the exact drop-in replacement is the SAUD50X125S, retaining the same body, bore, stroke, force, port, and FA/LB mounting.
The rear rod provides an anti-rotation benefit and can carry a sensor cam to drive two tools simultaneously. This unit has a built-in piston magnet (-S) for legacy CS1-B/DS1-B switches, whereas the SAUD replacement uses current CMSG/DMSG/EMSG sensors. For sizing, the computed safe working load is roughly 495 N (about 60% of the 825 N @0.5 MPa figure), and the vertical lift capacity is about 42 kg with a 2:1 margin. A plain cylinder does not hold its load on air loss; the cushion only decelerates near stroke end, so an external rod lock is needed for held loads.

The B06-SAUD50X125S 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.
Equal both-ways force drives precision stacking jigs in battery cell manufacturing, using the rear rod to synchronize a secondary cam.
Anti-rotation properties from the double-rod profile barrel accurately position battery modules on conveyor lines without torsional deflection.
Provides 825 N of equal push and pull force at 0.5 MPa to clamp battery tabs securely during automated welding processes.
To replace the discontinued B06-SUD50X125S, drop in the SAUD50X125S, which matches the 50mm bore, 125mm stroke, 1/4" port, and FA/LB mounting exactly. When sizing both ways, verify force against neighbouring bores: the 40mm yields 528/739/950 N and the 63mm yields 1402/1962/2523 N, while this 50mm provides equal both-ways force of 825/1154/1484 N. Choose a double-rod cylinder when you need anti-rotation or must drive two tools from one body. Note the -S sensor change from legacy CS1-B/DS1-B to CMSG/DMSG/EMSG. For strokes >=300mm, check the side-load line to prevent guide wear. Mounting is compatible with the AirTAC SC series only.
Replacement checklist
Yes, the B06-SUD50X125S is discontinued. The B06- prefix marks it as a battery-manufacturing dedicated variant of the SUD50X125S. The exact drop-in replacement is the SAUD50X125S, which is mechanically identical with the same bore, stroke, force, and 1/4" port. The SAUD also offers the SAUF built-in-valve variant the SU line lacked.
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 air port is 1/4". The safe working load is approximately 495 N. Note that the air cushion only decelerates the piston near stroke end and does not hold the load on air loss.
