This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B04-SAUD100X200S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B04-SAUD100X200S 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-SUD100X200S
The AirTAC Airtac B04-SUD Construction Machinery Special Standard Cylinder B04-SUD100X200S is a double-acting profile-type standard cylinder with a Ø100mm bore and 200mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the B04-SAUD100X200S, which matches its bore, stroke, force and mounting.

About the Airtac B04-SUD Construction Machinery Special Standard Cylinder B04-SUD100X200S
The B04-SUD100X200S is a double-acting, double-rod profile cylinder where the B04- prefix designates it as AirTAC's construction-machinery dedicated variant of the base SUD100X200S, mechanically identical in every spec. A rod exits both ends on a single piston, meaning push and pull force are equal both ways at 3681 N @0.5 MPa, 5153 N @0.7 MPa, and 6626 N @0.9 MPa. It features a 100mm bore, 25mm rod, 1/2" port, and M20x1.5 rod thread. This discontinued model is fully replaced by the drop-in SAUD100X200S.
Because the rear rod can carry a sensor cam or drive a second tool simultaneously, it provides excellent anti-rotation stability for heavy equipment. Using the 3681 N @0.5 MPa figure, the safe working load is roughly 2209 N, yielding a vertical lift capacity of about 188 kg with a 2:1 margin. The built-in piston magnet supports legacy CS1-B/DS1-B switches, while the SAUD replacement upgrades to current CMSG/DMSG/EMSG sensors. A plain cylinder does not hold loads on air loss; the 29mm adjustable cushions only decelerate near stroke end, so use an external rod lock for held loads.

Where the Airtac B04-SUD Construction Machinery Special Standard Cylinder B04-SUD100X200S Is Used
Excavator Actuation
Drives dual opposing mechanisms on heavy construction machinery where equal push and pull force is mandatory for balanced digging cycles.
Crane Load Transfer
Simultaneously operates two synchronized tooling arms from one body, utilizing the rear rod as a sensor cam for precise positioning feedback.
Heavy Equipment Guidance
Provides high anti-rotation stability for guiding structural components on site, handling safe working loads up to 2209 N without deflection.
Replacing the Airtac B04-SUD Construction Machinery Special Standard Cylinder B04-SUD100X200S with the B04-SAUD100X200S
To replace the discontinued B04-SUD100X200S, order the drop-in SAUD100X200S, which matches the 100mm bore, 200mm stroke, 1/2" port, and FA/LB mounting exactly. When sizing both ways, verify your force requirements against the equal both ways values (3681 N @0.5 MPa) and check neighbouring bores if you need a different capacity. A double rod is right when you need anti-rotation rigidity or must drive two tools from one cylinder. For the -S magnet option, plan a sensor change from legacy CS1-B/DS1-B to CMSG/DMSG/EMSG. For stroke lengths of 300mm or greater, carefully manage side-load alignment to prevent premature seal wear.
Replacement checklist
- ✓ Same bore / stroke → B04-SAUD100X200S
- ✓ 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-SUD100X200S FAQ
Yes, the B04-SUD100X200S is discontinued. The B04- prefix marks it as the construction-machinery dedicated variant of the base SUD100X200S. The exact drop-in replacement is the SAUD100X200S, which shares identical bore, stroke, force, and FA/LB mounting.
Because it is a double-rod cylinder, force is equal both ways: 3681 N @0.5 MPa, 5153 N @0.7 MPa, and 6626 N @0.9 MPa. The 100mm bore uses a 1/2" port, a 25mm rod, and M20x1.5 rod threads. The safe working load is approximately 2209 N.
