This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B04-SAID100X1000S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B04-SAID100X1000S 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-SID100X1000S
The AirTAC Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID100X1000S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 1000mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the B04-SAID100X1000S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID100X1000S
The AirTAC B04-SID100X1000S 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 AirTAC's construction-machinery dedicated variant, mechanically identical to the base SID100X1000S with a 100mm bore, 1000mm stroke, and G1/2 port. This legacy model is discontinued and replaced by the SAID100X1000S.
The SAID drop-in uses an upgraded two Y-shaped one-way piston seal for low start-up pressure and long life. The dual rods prevent rotation and allow driving two tools simultaneously. Computed buyer insight: safe working load is ~2209 N (60% of 3681 N), lifting ~188 kg vertically with a 2:1 margin. Note: air cushions only decelerate; use an external rod lock or SAIL/BSAI variant to hold loads.

Where the Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID100X1000S Is Used
Excavator Linkage Control
Drives dual opposing mechanical arms on heavy equipment where equal push/pull force and high side-load resistance are critical.
Crusher Feed Gate
Synced double-rod operation opens and closes heavy material gates on construction site crushers without rotational drift.
Paver Screed Actuator
Maintains precise screed height on road paving machinery using the rear rod for position feedback via a sensor cam.
Replacing the Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID100X1000S with the B04-SAID100X1000S
To replace the discontinued B04-SID100X1000S, use the SAID100X1000S, retaining the exact ISO 15552 interface, G1/2 port, and 1000mm stroke. Size both directions by checking equal force across neighbor bores (80mm yields 2268 N, 125mm yields 5734 N at 0.5 MPa). Choose a double-rod when anti-rotation or a back-rod sensor cam is needed. Mount via FA, LB, or TC. The -S magnet fits legacy CS1-B/DS1-B switches. For this 1000mm stroke, add external guides to prevent rod bending under side loads.
Replacement checklist
- ✓ Same ISO 15552 interface → B04-SAID100X1000S
- ✓ 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-SID100X1000S FAQ
Yes, it is discontinued. The exact drop-in replacement is the SAID100X1000S. The B04- prefix simply denotes the construction-machinery dedicated variant; the SAID replacement shares the exact 100mm bore, 1000mm stroke, G1/2 port, and ISO 15552 mounting.
Force is equal both ways: 3681 N @0.5 MPa, 5153 N @0.7 MPa, and 6626 N @0.9 MPa. Speed is 30-800 mm/s. It uses a G1/2 port and M20x1.5 rod thread. Remember, air cushions only decelerate; they do not hold loads without live air.
