This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B04-SAID100X800S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B04-SAID100X800S 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-SID100X800S
The AirTAC Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID100X800S 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-SAID100X800S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID100X800S
The AirTAC B04-SID100X800S is a double-acting, double-rod ISO 15552 cylinder where the B04- prefix designates it as a construction-machinery dedicated variant of the base SID100X800S. Because a rod exits both ends on a single 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. The bore is 100 mm, the port is G1/2, and the rod-end thread is M20x1.5. This legacy model is discontinued and is fully replaced by the SAID100X800S.
The drop-in SAID100X800S retains the exact ISO 15552 mounting interface, 800 mm stroke, and adjustable 36 mm air cushions at each end. The SAI replacement features an upgraded piston seal using two Y-shaped one-way elements for low start-up pressure and long life. For motion synchronization or driving two tools, the back rod can carry a sensor cam. Based on the 3681 N @0.5 MPa figure, the safe working load is roughly 2209 N, yielding a vertical lift capacity of about 188 kg with a 2:1 margin.

Where the Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID100X800S Is Used
Excavator Linkage Actuation
Provides equal push and pull force for synchronized movement of heavy-equipment covers or linkage arms where the back rod also drives a position sensor.
Loader Attachment Shift
Drives dual-tool attachments on construction machinery with anti-rotation stability, using the G1/2 port and 36 mm adjustable cushions to decelerate loads.
Crane Boom Extension
Handles extension and retraction tasks in heavy-equipment frames, offering 5153 N @0.7 MPa of equal force both ways for balanced load handling.
Replacing the Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID100X800S with the B04-SAID100X800S
To replace the discontinued B04-SID100X800S, order the SAID100X800S, which matches the G1/2 port, M20x1.5 thread, and 800 mm stroke. Because force is equal both ways, sizing is straightforward: if you need more force, step up to bore 125 (5734 N @0.5 MPa), or step down to bore 80 (2268 N @0.5 MPa). A double-rod design is right when you need anti-rotation resistance, external guidance from both faces, or a back rod for sensor cams. You can reuse FA, LB, or TC mounts. The -S suffix means a piston magnet is present for CS1-B/DS1-B switches. At 800 mm stroke, use external guides to prevent rod bending and side loads.
Replacement checklist
- ✓ Same ISO 15552 interface → B04-SAID100X800S
- ✓ 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-SID100X800S FAQ
Yes, it is discontinued. The exact drop-in replacement is the SAID100X800S. The B04- prefix simply marks it as construction-machinery dedicated; mechanically, it is identical to the base SID100X800S. The SAID replacement keeps the same ISO 15552 mounting, 100 mm bore, 800 mm stroke, G1/2 port, and force.
It is double-acting with equal force 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, with a proof pressure of 1.5 MPa. Speed is 30-800 mm/s. A plain cylinder does not hold loads on air loss; use an external rod lock or the SAIL/BSAI lock variant for held loads.
