This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B04-SAID100X800 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B04-SAID100X800 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-SID100X800
The AirTAC Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID100X800 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 800mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the B04-SAID100X800, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID100X800
The AirTAC B04-SID100X800 is a discontinued ISO 15552 double-rod cylinder. The B04- prefix marks it as a construction-machinery dedicated variant, mechanically identical to the base SID100X800. A rod exits both ends on one piston, meaning both faces use the rod-side area for equal push and pull force (3681 N at 0.5 MPa). The drop-in replacement is SAID100X800, which adds an upgraded two Y-shaped one-way piston seal for low start-up pressure and long life.
It features a 100 mm bore, G1/2 air port, M20x1.5 rod thread, and 36 mm adjustable cushions. Computed buyer insight: safe working load is 2209 N (60% of 3681 N), yielding a 188 kg vertical lift with a 2:1 margin. The rear rod can drive two tools or carry a sensor cam, though this non-S SKU cannot take a magnetic switch.

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-SAID100X800 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-SID100X800 Is Used
Excavator Boom Actuation
Drives dual-tool mechanisms on heavy equipment with equal push and pull force, preventing rotational drift during repetitive digging cycles.
Crusher Feed Control
Regulates material flow in construction-machinery crushers. The double-rod design ensures stable retraction under heavy vibration.
Paver Screed Adjustment
Positions asphalt paver screeds. The symmetrical force profile maintains precise leveling across the full 800 mm stroke.
Replacing the Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID100X800 with the B04-SAID100X800
To replace B04-SID100X800, use SAID100X800 (insert A after S). It preserves the ISO 15552 interface, G1/2 port, and 36 mm cushion. Size both ways by checking neighbor bores (80 mm or 125 mm) if you need different equal-both-ways force. Choose a double rod when you need anti-rotation or two-tool drive. Reuse FA, LB, or TC mounts. For the 800 mm stroke, add external guides to prevent rod bending under side loads. This SKU lacks the -S magnet, so it cannot accept sensors.
Replacement checklist
- ✓ Same ISO 15552 interface → B04-SAID100X800
- ✓ 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-SID100X800 FAQ
Yes, it is discontinued. The B04- prefix marks the construction-machinery dedicated variant of SID100X800. The exact drop-in replacement is SAID100X800, which shares the same ISO 15552 interface, bore, stroke, and G1/2 port.
Force is equal both ways: 3681 N at 0.5 MPa, 5153 N at 0.7 MPa, and 6626 N at 0.9 MPa. Safe working load is 2209 N (188 kg vertical lift with 2:1 margin). Note: air cushions only decelerate; use an external rod lock or SAIL/BSAI variant for load holding.
