This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B04-SAUD32X200S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B04-SAUD32X200S 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-SUD32X200S is a double-acting profile-type standard cylinder with a Ø32mm bore and 200mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the B04-SAUD32X200S, which matches its bore, stroke, force and mounting.
The AirTAC B04-SUD32X200S is a double-acting, double-rod profile cylinder where the B04- prefix marks it as the construction-machinery dedicated variant of the SUD32X200S, mechanically identical to the base model. A rod exits both ends of the extruded aluminum barrel on a single piston, meaning push and pull force are equal both ways at 345 N @0.5 MPa, 483 N @0.7 MPa, and 621 N @0.9 MPa. The compact profile body is shorter than an ISO 15552 cylinder of the same 32 mm bore. It features a 1/8" port, M10x1.25 rod thread, and adjustable air cushions at each end.
This discontinued model is fully replaced by the drop-in SAUD32X200S, which preserves the exact bore, stroke, equal-both-ways force, port, and FA/LB mounting. The rear rod provides an anti-rotation benefit and carries a sensor cam for stable guidance. For sizing, the safe working load is approximately 207 N (60% of the 345 N @0.5 force), allowing a vertical lift of about 18 kg with a 2:1 margin. Note that the SAUD upgrades the legacy CS1-B/DS1-B sensors to current CMSG/DMSG/EMSG switches.

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 and retracts a panel alignment tool on heavy equipment frames, using the rear rod for stable anti-rotation guidance.
Simultaneously actuates two synchronized tooling points from one compact profile body, fitting tight construction-machinery envelopes.
Shifts a diverter gate in both directions with equal 345 N @0.5 MPa force, relying on adjustable cushions to decelerate moving masses.
To replace the discontinued B04-SUD32X200S, specify the drop-in SAUD32X200S, which matches the 32 mm bore, 200 mm stroke, 1/8" port, and equal-both-ways force. When sizing both ways, verify force needs against neighboring bores, but the 32 mm offers 345 N @0.5 MPa. A double rod is right when you need anti-rotation stability or must drive two tools simultaneously. Mounting uses Basic, FA, or LB attachments compatible with the AirTAC SC series. Because this unit has the -S magnet, upgrade from legacy CS1-B/DS1-B to CMSG/DMSG/EMSG sensors. For this 200 mm stroke, ensure side-load alignment is within tolerance. A plain cylinder does not hold loads on air loss; use an external rod lock for held loads.
Replacement checklist
Yes, the B04-SUD32X200S is discontinued. The B04- prefix marks it as the construction-machinery dedicated variant of the base SUD32X200S. The exact drop-in replacement is the SAUD32X200S, which matches the 32 mm bore, 200 mm stroke, 1/8" port, and FA/LB mounting.
Because it is a double-rod cylinder, force is equal both ways: 345 N @0.5 MPa, 483 N @0.7 MPa, and 621 N @0.9 MPa. The safe working load is roughly 207 N. The air port is 1/8", the rod is Ø12 mm with an M10x1.25 thread, and speed ranges from 30-800 mm/s.
