This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B04-SAUD100X700S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B04-SAUD100X700S 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.
Airtac B04-SUD Construction Machinery Special Standard Cylinder B04-SUD100X700S
The AirTAC Airtac B04-SUD Construction Machinery Special Standard Cylinder B04-SUD100X700S is a double-acting profile-type standard cylinder with a Ø100mm bore and 700mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the B04-SAUD100X700S, which matches its bore, stroke, force and mounting.

About the Airtac B04-SUD Construction Machinery Special Standard Cylinder B04-SUD100X700S
The AirTAC B04-SUD100X700S is a double-acting, double-rod profile cylinder where the B04- prefix marks it as the construction-machinery dedicated variant of the SUD100X700S, 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 (3681 N at 0.5 MPa). It features a 100mm bore, 25mm rod, 1/2" port, and M20x1.5 rod thread. This discontinued model used legacy CS1-B/DS1-B sensors.
The exact drop-in replacement is the SAUD100X700S, which shares the same bore, stroke, equal force, port, and FA/LB mounting, but upgrades to current CMSG/DMSG/EMSG sensors. The extruded aluminum profile barrel is shorter than an ISO 15552 cylinder of the same bore. For this 700mm stroke, external guides are recommended to prevent rod bending. At 0.5 MPa, the safe working load is about 2209 N (60% of force), allowing a vertical lift of roughly 188 kg with a 2:1 margin.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |
| Max (@1.0 MPa) | 801 kgf | |
The B04-SAUD100X700S 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.

Where the Airtac B04-SUD Construction Machinery Special Standard Cylinder B04-SUD100X700S Is Used
Excavator Linkage Control
Drives dual-tool mechanisms on heavy equipment where equal push and pull force is required for precise positioning of construction machinery components.
Crane Load Sync
Uses the back rod to carry a sensor cam for synchronized heavy-equipment automation, relying on the double-rod design for strict anti-rotation.
Heavy Equipment Press
Handles pressing operations in construction machinery fabrication, utilizing the compact profile barrel and 29mm adjustable cushions at each end.
Replacing the Airtac B04-SUD Construction Machinery Special Standard Cylinder B04-SUD100X700S with the B04-SAUD100X700S
To replace the B04-SUD100X700S, use the drop-in SAUD100X700S, matching the 100mm bore, 700mm stroke, 1/2" port, and FA/LB mounting. When sizing both ways, verify the equal-both-ways force (3681 N @0.5 MPa) meets your needs, or step to neighbor bores. A double rod is right when you need anti-rotation, a back rod to carry a sensor cam, or to drive two tools. The -S sensor changes from CS1-B/DS1-B to CMSG/DMSG/EMSG. For this 700mm stroke, add external guides to handle side-load and rod-bending.
Replacement checklist
- ✓ Same bore / stroke → B04-SAUD100X700S
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S): sensor family CS1-B → CMSG
- ✓ Mounting reused (FA/FB/CA/CB/LB)
- ✓ Need a built-in valve? → SAUF
Airtac B04-SUD Construction Machinery Special Standard Cylinder B04-SUD100X700S FAQ
Yes, the B04-SUD100X700S is discontinued. The B04- prefix marks it as the construction-machinery dedicated variant of SUD100X700S. The exact drop-in replacement is the SAUD100X700S, which is mechanically identical in bore, stroke, force, port, and FA/LB mounting.
Force is equal both ways: 3681 N @0.5 MPa, 5153 N @0.7 MPa, and 6626 N @0.9 MPa. The 1/2" port and 25mm rod are fixed by the 100mm bore. The -S magnet works with legacy CS1-B/DS1-B switches (the SAUD replacement uses CMSG/DMSG/EMSG). A plain cylinder does not hold loads on air loss; use an external rod lock.
