This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B04-SAID100X150 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B04-SAID100X150 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-SID100X150
The AirTAC Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID100X150 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-SAID100X150, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID100X150
The AirTAC B04-SID100X150 is a double-acting, double-rod ISO 15552 cylinder where the B04- prefix marks it as the construction-machinery dedicated variant of the base SID100X150, mechanically identical to it. Because a rod exits both ends on one piston, both faces use the rod-side area, making push and pull force equal at 3681 N @0.5 MPa, 5153 N @0.7 MPa, and 6626 N @0.9 MPa. It features a 100mm bore, 150mm stroke, G1/2 port, M20x1.5 rod thread, and 36mm adjustable cushions. This legacy SID is discontinued; the exact drop-in replacement is the SAID100X150, which reuses the same ISO 15552 mounting interface, bore, stroke, and port.
The double-rod design provides anti-rotation stability and allows the back rod to drive a second tool or carry a sensor cam. The SAI upgrade uses an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and long life. This SKU has no -S magnet and cannot take a switch. A plain cylinder does not hold loads on air loss; cushions only decelerate. For safe sizing, the computed safe working load is ~2209 N (60% of 3681 N), yielding a ~188 kg vertical lift 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 | — |

Where the Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID100X150 Is Used
Excavator Linkage Control
Drives synchronized heavy-equipment covers on construction machinery where equal push/pull force and anti-rotation stability are critical.
Dual-Tool Actuation
Uses the rear rod extension to operate a secondary valve or mechanism simultaneously from the same 100mm bore cylinder.
Crusher Feed Gate
Regulates aggregate flow in construction-machinery crushers, relying on the 36mm cushions to decelerate heavy dynamic loads.
Replacing the Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID100X150 with the B04-SAID100X150
To replace the discontinued B04-SID100X150, order the SAID100X150 drop-in: it matches the 100mm bore, 150mm stroke, G1/2 port, and ISO 15552 dimensions. Size both ways by checking equal-both-ways force against your load; if 5153 N @0.7 MPa is excessive, step down to the 80mm bore (3175 N @0.7), or if insufficient, step up to 125mm (8028 N @0.7). A double rod is right when you need anti-rotation or a back-end cam. Reuse FA, LB, or TC mounts. As this SKU lacks the -S magnet, it cannot accept sensors. For strokes >=300mm, verify side-load bearing limits.
Replacement checklist
- ✓ Same ISO 15552 interface → B04-SAID100X150
- ✓ 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-SID100X150 FAQ
Yes, the B04-SID100X150 (construction-machinery dedicated SID100X150) is discontinued. The exact drop-in replacement is the SAID100X150. It shares the identical ISO 15552 interface, 100mm bore, 150mm stroke, G1/2 port, and mounting, while adding 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. The safe working load is ~2209 N (60% of the 0.5 MPa rating), allowing a ~188 kg vertical lift with a 2:1 margin. Note that air cushions only decelerate; use an external rod lock or SAIL/BSAI variant for load holding.
