This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B04-SAUD100X600S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B04-SAUD100X600S 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 B04-SUD Construction Machinery Special Standard Cylinder B04-SUD100X600S is a double-acting profile-type standard cylinder with a Ø100mm bore and 600mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the B04-SAUD100X600S, which matches its bore, stroke, force and mounting.
The AirTAC B04-SUD100X600S is a double-acting, double-rod profile cylinder where the B04- prefix designates it as the construction-machinery dedicated variant of the SUD100X600S, mechanically identical to the base model. A rod exits both ends on one piston, meaning both faces use the rod-side area and push and pull force are equal. The extruded aluminium profile barrel is shorter than an ISO 15552 cylinder of the same bore. This discontinued model features a 100mm bore, 600mm stroke, 1/2 inch port, M20x1.5 rod thread, and a 29mm adjustable air cushion at each end. The exact drop-in replacement is the SAUD100X600S, retaining the same force, port, and FA/LB mounting.
Force is equal both ways: 3681 N at 0.5 MPa, 5153 N at 0.7 MPa, and 6626 N at 0.9 MPa. From the 0.5 MPa figure, the safe working load is about 2209 N, yielding a vertical lift capacity of 188 kg with a 2:1 margin. The double-rod design prevents rotation and allows the back rod to carry a sensor cam. This unit includes a piston magnet for legacy CS1-B/DS1-B switches, while the SAUD replacement uses current CMSG/DMSG/EMSG sensors. A plain cylinder does not hold its load on air loss; the cushion only decelerates near stroke end, so use an external rod lock for held loads.

The B04-SAUD100X600S 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.

| -S | Optional built-in magnet for sensor position sensing. |
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.
Drives synchronized gripper arms on heavy equipment where equal push and pull force prevents uneven jaw closure under high load.
Pushes heavy construction components between stations using both rod ends to maintain precise alignment without rotation.
Shifts heavy pallets in construction yards, utilizing the back rod to trigger limit switches for automated sequencing.
To replace the discontinued B04-SUD100X600S, use the drop-in SAUD100X600S, which matches the 100mm bore, 600mm stroke, 1/2 inch port, and FA/LB mounting. When sizing both ways, verify force needs against neighbouring bores, noting this 100mm bore provides 3681 N both ways at 0.5 MPa. A double rod is right when you need anti-rotation or a back rod to drive two tools. The -S sensor changes from CS1-B/DS1-B to CMSG/DMSG/EMSG. For this 600mm stroke, add external guides to prevent rod bending and side-load wear.
Replacement checklist
Yes, it is discontinued. The B04- prefix marks the construction-machinery dedicated variant of SUD100X600S. The exact drop-in replacement is the SAUD100X600S, matching the bore, stroke, 1/2 inch port, and FA/LB mounting.
Force is equal both ways at 3681 N at 0.5 MPa, 5153 N at 0.7 MPa, and 6626 N at 0.9 MPa. The air port is 1/2 inch. The safe working load is about 2209 N, allowing a 188 kg vertical lift with a 2:1 margin.
