This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B04-SAUD100X150S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B04-SAUD100X150S 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-SUD100X150S
The AirTAC Airtac B04-SUD Construction Machinery Special Standard Cylinder B04-SUD100X150S is a double-acting profile-type standard cylinder with a Ø100mm bore and 150mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the B04-SAUD100X150S, which matches its bore, stroke, force and mounting.

About the Airtac B04-SUD Construction Machinery Special Standard Cylinder B04-SUD100X150S
The B04-SUD100X150S is a discontinued AirTAC double-rod profile cylinder where the B04- prefix designates it as a construction-machinery dedicated variant of the SUD100X150S, 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. It delivers 3681 N at 0.5 MPa, 5153 N at 0.7 MPa, and 6626 N at 0.9 MPa. The extruded aluminium profile barrel is shorter than an ISO 15552 cylinder of the same 100 mm bore. It features a 25 mm rod, M20x1.5 rod-end thread, a 1/2 inch port, and 29 mm adjustable air cushions.
As this SUD series is end-of-life, the exact drop-in replacement is the SAUD100X150S, which retains the same bore, stroke, equal-both-ways force, 1/2 inch port, and FA/LB mounting. The SAU replacement uses current CMSG/DMSG/EMSG sensors, whereas this discontinued model used legacy CS1-B/DS1-B switches. For sizing, the equal force yields a safe working load of about 2209 N (60 percent of the 3681 N at 0.5 MPa figure) and a vertical lift capacity of 188 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 use an external rod lock for held loads.

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-SAUD100X150S 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-SUD100X150S Is Used
Heavy Equipment Actuation
Drives synchronized mechanisms on construction machinery where the B04- prefix indicates dedicated heavy-equipment integration.
Dual-Tool Push-Pull Stations
Uses the rear rod extension to operate a secondary tool or sensor cam, benefiting from equal force in both directions.
Anti-Rotation Handling
Handles materials in rugged plant environments where the double-rod design prevents piston rotation during transfer.
Replacing the Airtac B04-SUD Construction Machinery Special Standard Cylinder B04-SUD100X150S with the B04-SAUD100X150S
To replace the B04-SUD100X150S, order the drop-in SAUD100X150S, which matches the 100 mm bore, 150 mm stroke, 1/2 inch port, and FA/LB mounting. When sizing both ways, verify the equal push and pull force against neighbour bores, noting this 100 mm bore provides 3681 N at 0.5 MPa. A double rod is right when you need anti-rotation stability or must drive two tools simultaneously. The -S suffix on this unit means it has a piston magnet for legacy CS1-B/DS1-B switches; the SAU replacement requires current CMSG/DMSG/EMSG sensors. For strokes of 300 mm or longer, carefully manage side-load alignment to prevent guide wear.
Replacement checklist
- ✓ Same bore / stroke → B04-SAUD100X150S
- ✓ 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-SUD100X150S FAQ
Yes, the B04-SUD100X150S is discontinued. The B04- prefix marks it as a construction-machinery dedicated variant of the SUD100X150S. The exact drop-in replacement is the SAUD100X150S, which is mechanically identical in bore, stroke, 1/2 inch port, and force.
Because it is a double-rod cylinder, force is equal both ways: 3681 N at 0.5 MPa, 5153 N at 0.7 MPa, and 6626 N at 0.9 MPa. The bore is 100 mm, the port is 1/2 inch, and it uses a 25 mm rod with an M20x1.5 thread.
