This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B04-SAUD100X600 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B04-SAUD100X600 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-SUD100X600 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-SAUD100X600, which matches its bore, stroke, force and mounting.
The AirTAC B04-SUD100X600 is a double-acting, double-rod profile cylinder where a rod exits both ends, ensuring push and pull force are equal at 3681 N @0.5 MPa, 5153 N @0.7 MPa, and 6626 N @0.9 MPa. The B04- prefix marks this as a construction-machinery dedicated variant, mechanically identical to the standard SUD100X600 with a 100mm bore, 600mm stroke, 1/2" port, and M20x1.5 rod thread. This discontinued model used legacy CS1-B/DS1-B sensors and lacks a magnet for position sensing.
The exact drop-in replacement is the SAUD100X600, which matches the bore, stroke, equal force, port, and FA/LB mounting. The SAUD upgrades to current CMSG/DMSG/EMSG sensors. With a 3681 N force at 0.5 MPa, the computed safe working load is roughly 2209 N, allowing a vertical lift of about 188 kg with a 2:1 margin. The double-rod design prevents rotation and lets the back rod carry a sensor cam or drive a second tool. Note that air cushions only decelerate the piston; an external rod lock is required to hold loads.

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 dual opposing arms on heavy equipment where equal push and pull force prevents linkage binding.
Simultaneously operates two crushing jaws from one body, using the anti-rotation property of the dual rods.
Keeps heavy machinery forks aligned under load by driving both ends through the 600mm stroke.
To replace the discontinued B04-SUD100X600, use the drop-in SAUD100X600, which preserves the 100mm bore, 600mm stroke, 1/2" port, and FA/LB mounting. Because force is equal both ways, size both directions by checking neighboring bores if you need less force. A double rod is right when you need anti-rotation, a back rod for a sensor cam, or two tools driven simultaneously. If switching from a non-magnet SUD to an -S SAUD, note the sensor change from CS1-B/DS1-B to CMSG/DMSG/EMSG. For this 600mm stroke, use external guides to prevent rod bending and side loads.
Replacement checklist
Yes, it is discontinued. The exact drop-in replacement is the SAUD100X600, which matches the 100mm bore, 600mm stroke, 1/2" port, and FA/LB mounting. The B04- prefix simply marks it as construction-machinery dedicated, so the SAUD is mechanically identical.
Force is equal both ways: 3681 N @0.5 MPa, 5153 N @0.7 MPa, and 6626 N @0.9 MPa. This specific SKU has no magnet and cannot take a switch. The SAUD replacement uses CMSG/DMSG/EMSG sensors.
