This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B04-SAUD32X200 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B04-SAUD32X200 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-SUD32X200
The AirTAC Airtac B04-SUD Construction Machinery Special Standard Cylinder B04-SUD32X200 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-SAUD32X200, which matches its bore, stroke, force and mounting.

About the Airtac B04-SUD Construction Machinery Special Standard Cylinder B04-SUD32X200
The AirTAC B04-SUD32X200 is a double-acting, double-rod profile cylinder discontinued and directly replaced by the SAUD32X200. The B04- prefix marks this as a construction-machinery dedicated variant of the base SUD32X200, mechanically identical with the same 32mm bore, 200mm stroke, and 1/8" port. A rod exits both ends on one piston, meaning both faces use the rod-side area, so push and pull force are equal at 345N @0.5 MPa, 483N @0.7 MPa, and 621N @0.9 MPa. The extruded aluminum profile barrel is shorter than an ISO 15552 cylinder of the same bore.
Because the rear rod can carry a sensor cam or drive a second tool simultaneously while resisting rotation, double-rod designs excel in heavy-equipment builds. Based on the 345N @0.5 MPa rating, the safe working load is roughly 207N, allowing a vertical lift of about 18kg with a 2:1 margin. Note this SKU lacks a magnet and cannot take a sensor; the SAUD upgrade uses current CMSG/DMSG/EMSG sensors where the SUD used legacy CS1-B/DS1-B. Air cushions only decelerate near stroke end, so use an external rod lock for held loads.

Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |

Where the Airtac B04-SUD Construction Machinery Special Standard Cylinder B04-SUD32X200 Is Used
Excavator Linkage Actuation
Drives synchronized dual-tool mechanisms on heavy-equipment builds where the B04- construction-machinery prefix is specified, using the rear rod as an anti-rotation guide.
Crane Counterweight Shift
Moves ballast brackets with equal push and pull force, ensuring stable positioning without drift when live air is applied to the 32mm bore profile body.
Loader Arm Synchronization
Simultaneously pushes two linkages from one piston, keeping loader arms aligned during material handling while maintaining a compact footprint.
Replacing the Airtac B04-SUD Construction Machinery Special Standard Cylinder B04-SUD32X200 with the B04-SAUD32X200
To replace the discontinued B04-SUD32X200, select the drop-in SAUD32X200, which matches the 32mm bore, 200mm stroke, 1/8" port, and FA/LB mounting. When sizing both ways, verify the equal both-ways force fits your load: this 32mm bore provides 345N @0.5 MPa, while the neighbor 40mm bore provides 528N. Choose a double-rod cylinder when you need anti-rotation stability or to drive two tools from one piston. Mounting is compatible with the AirTAC SC series only. Since this non-magnetic SKU cannot take a switch, upgrading to the SAUD with an -S suffix allows modern CMSG/DMSG/EMSG sensors. For this 200mm stroke, check side-load alignment to prevent guide wear.
Replacement checklist
- ✓ Same bore / stroke → B04-SAUD32X200
- ✓ 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-SUD32X200 FAQ
Yes, the B04-SUD32X200 is discontinued. The exact drop-in replacement is the SAUD32X200, which shares the same 32mm bore, 200mm stroke, 1/8" port, and FA/LB mounting. The B04- prefix simply marks it as the construction-machinery dedicated variant of the base SUD32X200, so all physical specs remain identical.
Because it is a double-rod cylinder, force is equal both ways: 345N @0.5 MPa, 483N @0.7 MPa, and 621N @0.9 MPa. The air port is 1/8" PT thread. The safe working load is approximately 207N, which yields an 18kg vertical lift capacity with a 2:1 margin.
