This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B04-SAID100X600S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B04-SAID100X600S in place of this model. The SAI replacement keeps the same ISO 15552 mounting interface, bore, stroke, output force and accessories, so it drops straight into existing fixtures. It is the current-production version of this cylinder with an upgraded piston seal.
Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID100X600S
The AirTAC Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID100X600S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 600mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the B04-SAID100X600S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID100X600S
The AirTAC B04-SID100X600S is a double-acting, double-rod ISO 15552 cylinder where a rod exits both ends, making push and pull force equal at 3681 N @0.5 MPa, 5153 N @0.7 MPa, and 6626 N @0.9 MPa. The B04- prefix marks this as AirTAC's construction-machinery dedicated variant of the base SID100X600S, mechanically identical in its 100mm bore, 600mm stroke, G1/2 port, M20x1.5 rod thread, and 36mm adjustable cushions. This SID model is discontinued and the exact drop-in replacement is the SAID100X600S.
The SAID upgrade introduces a two Y-shaped one-way piston seal for lower start-up pressure and longer life, while retaining the exact ISO 15552 mounting interface. The dual-rod design prevents rotation and allows the back rod to carry a sensor cam for the -S magnet (legacy CS1-B/DS1-B). For sizing, the safe working load is ~2209 N (60% of the 3681 N @0.5 figure), yielding a vertical lift capacity of ~188 kg with a 2:1 margin. Note that air cushions only decelerate; for load holding on air loss, use an external rod lock or SAIL/BSAI variant.

Where the Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID100X600S Is Used
Excavator Actuation
Drives synchronized heavy-equipment covers on construction machinery, using the dual-rod design to prevent rotation during harsh off-axis vibrations.
Crusher Tooling
Simultaneously pushes and pulls opposing wear plates in material crushers, leveraging equal force both ways for balanced crushing pressure.
Loader Diverter
Shifts heavy aggregate diverters on loading conveyors, using the back rod to carry a sensor cam for precise position feedback.
Replacing the Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID100X600S with the B04-SAID100X600S
To replace the discontinued B04-SID100X600S, specify the SAID100X600S, which matches the 100mm bore, 600mm stroke, G1/2 port, and equal-both-ways force. When sizing both ways, verify your load against the 3681 N @0.5 MPa limit, or step to a 125mm bore if higher force is needed. A double rod is right when you need anti-rotation or must drive two tools simultaneously. Reuse FA, LB, or TC mounts directly. The -S suffix indicates a piston magnet for switches. Because stroke is 600mm, external guides are required to manage side loads and prevent rod bending.
Replacement checklist
- ✓ Same ISO 15552 interface → B04-SAID100X600S
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID100X600S FAQ
Yes, the B04-SID100X600S is discontinued. The exact drop-in replacement is the SAID100X600S. The B04- prefix simply marks it as the construction-machinery dedicated variant; mechanically, it is identical to the base SID100X600S. The SAID keeps the same ISO 15552 mounting, 100mm bore, 600mm stroke, G1/2 port, and force.
Force is equal both ways due to the double-rod design: 3681 N @0.5 MPa, 5153 N @0.7 MPa, and 6626 N @0.9 MPa. Speed is 30-800 mm/s. The air port is G1/2. Note that the air cushion only decelerates near stroke end; it does not hold the load on air loss, so an external rod lock is needed for held loads.
