This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B04-SAID100X200 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B04-SAID100X200 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-SID100X200 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 200mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the B04-SAID100X200, which matches its ISO interface, bore, stroke, force and mounting.
The AirTAC B04-SID100X200 is a double-acting, double-rod ISO 15552 cylinder where a rod exits both ends, yielding equal push and pull force of 3681 N at 0.5 MPa. The B04- prefix marks this as AirTAC's construction-machinery dedicated variant of the base SID100X200, mechanically identical to the standard line with a 100mm bore, 200mm stroke, and G1/2 port. This legacy model is discontinued and directly replaced by the SAID100X200.
The SAID100X200 drop-in replacement retains the exact ISO 15552 mounting interface, bore, and stroke, while adding an upgraded two-piece Y-shaped piston seal for lower start-up pressure. Because both faces use the rod-side area, force is equal both ways (3681/5153/6626 N at 0.5/0.7/0.9 MPa). The dual rods prevent rotation and can drive two tools simultaneously. Computed buyer insight: safe working load is roughly 2209 N (60% of the 0.5 MPa force), allowing a vertical lift of about 188 kg with a 2:1 margin. Note this SKU lacks a -S magnet and cannot mount sensors.

The B04-SAID100X200 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).
Synchronizes dual hydraulic valve covers on heavy construction equipment using equal both-ways force and anti-rotation stability.
Drives two opposing tooling arms on a crane boom fixture, benefiting from the 100mm bore's 3681 N force at 0.5 MPa.
Shifts screed alignment plates on road paving machinery, utilizing the G1/2 port and ISO 15552 mounting for rigid frame integration.
To replace the discontinued B04-SID100X200, specify the SAID100X200, which is a true drop-in upgrade retaining the G1/2 port, M20x1.5 rod thread, and 36mm adjustable cushions. Size both ways by verifying the equal push/pull force of 3681 N at 0.5 MPa; if less force is acceptable, the neighbouring 80mm bore provides 2268 N, while the 125mm bore offers 5734 N. A double-rod design is correct when you need anti-rotation stability or must drive two mechanisms in opposite directions. Mounting options include Basic, FA, LB, and TC brackets. For strokes of 300mm or longer, account for side-load deflection. This non-magnetic SKU cannot accept switches; for load-holding, use an external rod lock or the SAIL/BSAI variants, as air cushions only decelerate.
Replacement checklist
Yes, the B04-SID100X200 construction-machinery dedicated cylinder is discontinued. The exact drop-in replacement is the SAID100X200. It shares the identical ISO 15552 interface, 100mm bore, 200mm stroke, and G1/2 port, while adding an upgraded piston seal. The B04- prefix simply denotes the construction industry variant, and the SAID replacement matches all physical specs.
Because it is a double-rod cylinder, the push and pull force are equal both ways: 3681 N at 0.5 MPa, 5153 N at 0.7 MPa, and 6626 N at 0.9 MPa. The air port is G1/2, the rod thread is M20x1.5, and it features 36mm adjustable cushions at each end. The safe working load is approximately 2209 N, yielding a 188 kg vertical lift capacity with a 2:1 margin.
