This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B04-SAID100X500S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B04-SAID100X500S 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-SID100X500S
The AirTAC Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID100X500S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 500mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the B04-SAID100X500S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID100X500S
The AirTAC B04-SID100X500S 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 of the base SID100X500S, mechanically identical with a 100mm bore, 500mm stroke, G1/2 port, and M20x1.5 rod thread. This SID series is discontinued and is fully replaced by the drop-in SAID100X500S, which reuses the exact ISO 15552 mounting interface and adds an upgraded two-piece Y-shaped piston seal for lower start-up pressure.
Because both faces use the rod-side area, the equal-both-ways force yields a safe working load of roughly 2209 N (about 60% of the 0.5 MPa rating) and a vertical lift capacity of 188 kg with a 2:1 margin. The rear rod can drive a second tool or carry a sensor cam for synchronized tracking. Note that a plain cylinder does not hold loads on air loss; the 36 mm adjustable cushions only decelerate near stroke end. For held loads, use an external rod lock or the SAIL/BSAI lock variants.

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-SAID100X500S 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-SID100X500S Is Used
Excavator Linkage Control
Uses the equal-both-ways force to drive heavy construction machinery linkage components with stable push and pull motion.
Heavy Equipment Positioning
The dual rods prevent rotation during long 500mm strokes, ensuring precise alignment of structural welding fixtures.
Synchronized Tool Drive
The extending rear rod simultaneously operates a secondary valve or sensor cam on heavy equipment assemblies.
Replacing the Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID100X500S with the B04-SAID100X500S
To replace the discontinued B04-SID100X500S, select the SAID100X500S, which matches the 100mm bore, 500mm stroke, G1/2 port, and ISO 15552 mounting dimensions (Basic, FA, LB, TC) without mechanical changes. Size both directions by the equal-both-ways force: 3681 N @0.5 MPa, 5153 N @0.7 MPa, or 6626 N @0.9 MPa. If you need less force, the neighboring 80mm bore offers 2268 N @0.5 MPa; if you need more, the 125mm bore provides 5734 N @0.5 MPa. Choose a double-rod cylinder when you need anti-rotation stability or equal drive on both strokes. The -S suffix indicates a built-in piston magnet for legacy CS1-B/DS1-B switches. Because the stroke is 500mm, add external guides to prevent rod bending under side loads.
Replacement checklist
- ✓ Same ISO 15552 interface → B04-SAID100X500S
- ✓ 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-SID100X500S FAQ
Yes, the B04-SID100X500S is discontinued. The exact drop-in replacement is the SAID100X500S. The B04- prefix simply marks it as the construction-machinery dedicated variant of the base SID100X500S, so all physical specs (100mm bore, 500mm stroke, G1/2 port, M20x1.5 thread) are identical. The SAI family also adds the SAIL and BSAI lock variants.
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 air port is G1/2. The cylinder operates at 0.15-1.0 MPa with a speed range of 30-800 mm/s. It does not hold loads without live air; use an external rod lock for load holding.
