This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B04-SAID100X600 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B04-SAID100X600 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-SID100X600
The AirTAC Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID100X600 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 600mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the B04-SAID100X600, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID100X600
The AirTAC B04-SID100X600 is a double-acting, double-rod ISO 15552 cylinder where a rod exits both ends, ensuring push and pull force are equal at 3681 N @0.5 MPa. The B04- prefix marks this as AirTAC's construction-machinery dedicated variant, mechanically identical to the base SID100X600 with a 100mm bore, 600mm stroke, G1/2 port, and M20x1.5 rod thread. This SKU has no -S magnet and cannot carry sensors. As the SID line is discontinued, the direct drop-in replacement is the SAID100X600, reusing the exact ISO 15552 mounting interface.
The SAID upgrade introduces a two Y-shaped one-way piston seal for lower start-up pressure and longer life. Because the second rod acts as an anti-rotation guide and can drive a second tool, it suits heavy equipment. Based on the 3681 N @0.5 MPa force, the safe working load is ~2209 N, yielding a vertical lift capacity of ~188 kg with a 2:1 margin. Note that air cushions only decelerate; for load holding on air loss, use an external rod lock or SAIL/BSAI variant.

Where the Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID100X600 Is Used
Excavator Linkage Control
Uses the equal both-ways force and dual rods to drive heavy construction machinery linkages, ensuring stable bidirectional positioning without rotational play.
Heavy Equipment Clamping
The second rod drives an opposing clamp or synchronizes a secondary mechanism, leveraging the 3681 N @0.5 MPa force for rigid workholding on heavy equipment frames.
Synchronized Actuation
The rear rod simultaneously moves a secondary valve or indicator, utilizing the equal push/pull dynamics to maintain timing across construction machinery cycles.
Replacing the Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID100X600 with the B04-SAID100X600
To replace the discontinued B04-SID100X600, order the SAID100X600, which matches the 100mm bore, 600mm stroke, G1/2 port, and FA/LB/TC mounting footprint. Size both directions by the equal force: 5153 N @0.7 MPa or 6626 N @0.9 MPa. If less force is needed, neighboring bores like 80mm offer 2268 N @0.5 MPa; for more, the 125mm provides 5734 N @0.5 MPa. A double rod is right when you need anti-rotation or dual-tool drive without external guides. For this 600mm stroke, external guides are recommended to prevent rod bending under side loads. Choose the -S magnet option if sensor tracking is required, as this plain SKU lacks sensing.
Replacement checklist
- ✓ Same ISO 15552 interface → B04-SAID100X600
- ✓ 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-SID100X600 FAQ
Yes, the SID line is discontinued. The exact drop-in replacement is the SAID100X600. The B04- prefix simply marks it as construction-machinery dedicated; the SAID matches its 100mm bore, 600mm stroke, G1/2 port, and ISO 15552 mounting.
The G1/2 port feeds a 25mm rod. 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. Air cushions only decelerate; use an external rod lock for load holding.
