This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B04-SAID100X1000 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B04-SAID100X1000 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.

The AirTAC Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID100X1000 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-SAID100X1000, which matches its ISO interface, bore, stroke, force and mounting.
The AirTAC B04-SID100X1000 is a double-acting, double-rod ISO 15552 cylinder where the B04- prefix marks it as a construction-machinery dedicated variant; mechanically, it is identical to the standard SID100X1000. Because a rod exits both ends, the push and pull forces are equal at 3681 N (@0.5 MPa). This model is discontinued. The direct drop-in replacement is the SAID100X1000, which retains the exact 1000 mm stroke, G1/2 port, M20x1.5 rod thread, and ISO 15552 mounting interface.
The SAI replacement upgrades the piston seal to two Y-shaped one-way elements for lower start-up pressure and longer life. For sizing, the safe working load is roughly 2209 N (60% of the 3681 N @0.5 MPa force), translating to a vertical lift capacity of about 188 kg with a 2:1 margin. Note this SKU lacks a magnet (-S), so it cannot accept magnetic switches. A plain cylinder will drift on air loss, so use an external rod lock for held loads.

The B04-SAID100X1000 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.

Legacy SI-family variants: SID (double rod), SIJ (adjustable stroke) — each maps to its SAI equivalent (SID→SAID, SIJ→SAIJ). Rod material: carbon steel (blank) / SUS420J2 (A) / SUS304 (B).
Provides equal push and pull force for synchronized positioning of heavy-equipment covers or linkage arms on construction machinery.
Drives opposing tooling simultaneously in aggregate processing equipment, utilizing the dual-rod outputs for balanced material handling.
Maintains anti-rotation stability and equal force both ways for adjusting discharge gates on road paving machinery.
To replace the discontinued B04-SID100X1000, use the SAID100X1000 directly; it preserves the 100 mm bore, 1000 mm stroke, and equal both-ways force. When sizing both ways, verify the 3681 N (@0.5 MPa) output meets your needs, or step to neighbouring bores if higher force is required. A double-rod design is right when you need anti-rotation stability or must drive two tools simultaneously. Mounting options include Basic, FA, LB, and TC. Because the stroke is 1000 mm, add external guides to prevent rod bending under side-loads.
Replacement checklist
Yes, it is discontinued. The B04- prefix simply marks it as the construction-machinery dedicated variant of the base SID100X1000. The exact drop-in replacement is the SAID100X1000, which matches the ISO 15552 interface, bore, stroke, and G1/2 port.
Force is equal both ways at 3681 N @0.5 MPa, 5153 N @0.7 MPa, and 6626 N @0.9 MPa. The air port is G1/2. Note that a plain cylinder does not hold loads on air loss; the 36 mm cushion only decelerates near stroke end, so use an external rod lock for held loads.
