This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B04-SAID100X150S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B04-SAID100X150S 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-SID100X150S
The AirTAC Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID100X150S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 150mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the B04-SAID100X150S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID100X150S
The AirTAC B04-SID100X150S 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. The B04- prefix marks this as a construction-machinery dedicated variant, mechanically identical to the standard SID100X150S with a 100mm bore, 150mm stroke, G1/2 port, and M20x1.5 rod thread. This legacy model is discontinued.
The direct drop-in replacement is the SAID100X150S, which reuses the exact ISO 15552 mounting interface and adds an upgraded piston seal with two Y-shaped one-way elements for lower start-up pressure. The dual-rod design prevents rotation and lets the back rod carry a sensor cam. For sizing, the safe working load is ~2209 N (60% of the 3681 N force), allowing a vertical lift of ~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-SAID100X150S 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-SID Construction Machinery Special ISO Standard Cylinder B04-SID100X150S Is Used
Excavator Linkage Control
Drives synchronized actuation points on heavy equipment attachments, utilizing the equal push/pull force to maintain balanced positioning under varying hydraulic pressures.
Crane Slewing Brakes
Provides anti-rotation rigidity for braking mechanisms on construction cranes, ensuring stable deceleration with its 36mm adjustable cushions at both ends.
Loader Boom Alignment
Powers dual-tool alignment on front loaders, using the back rod to carry a sensor cam for precise stroke feedback in harsh environments.
Replacing the Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID100X150S with the B04-SAID100X150S
To replace the discontinued B04-SID100X150S, use the SAID100X150S; it matches the 100mm bore, 150mm stroke, G1/2 port, and 3681 N equal-both-ways force. Choose a double-rod cylinder when you need anti-rotation stability or must drive two tools simultaneously. Mounting options include Basic, FA, LB, and TC. The -S suffix means a piston magnet is present for legacy CS1-B/DS1-B switches. For strokes of 300mm or longer, verify side-load limits. Note that air cushions only decelerate; for load holding without live air, use an external rod lock or the SAIL/BSAI variants.
Replacement checklist
- ✓ Same ISO 15552 interface → B04-SAID100X150S
- ✓ 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-SID100X150S FAQ
Yes, the B04-SID100X150S (construction-machinery dedicated SID100X150S) is discontinued. The exact drop-in replacement is the SAID100X150S. It shares the same ISO 15552 mounting interface, 100mm bore, 150mm stroke, G1/2 port, and equal-both-ways force, but adds an upgraded piston seal.
Force is equal both ways: 3681 N @0.5 MPa, 5153 N @0.7 MPa, and 6626 N @0.9 MPa. Operating pressure is 0.15-1.0 MPa. Speed ranges 30-800 mm/s. The safe working load is ~2209 N, allowing a vertical lift of ~188 kg with a 2:1 margin.
