This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B04-SAID100X700S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B04-SAID100X700S 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-SID100X700S
The AirTAC Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID100X700S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 700mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the B04-SAID100X700S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID100X700S
The AirTAC B04-SID100X700S is a double-acting, double-rod ISO 15552 cylinder where a rod exits both ends, yielding equal force in both directions (3681 N at 0.5 MPa). The B04- prefix marks this as AirTAC's construction-machinery dedicated variant, mechanically identical to the base SID100X700S. It features a 100 mm bore, G1/2 port, M20x1.5 rod thread, and a 700 mm stroke. This SID model is discontinued; the drop-in replacement is the SAID100X700S.
The SAI replacement uses an upgraded two Y-shaped one-way piston seal for low start-up pressure and long life. A rear rod provides anti-rotation support and can carry a sensor cam. Computed buyer insight: safe working load is ~2209 N (60% of 3681 N), enabling a vertical lift of ~188 kg with a 2:1 margin. Note that air cushions only decelerate; use an external rod lock or SAIL/BSAI variant for load holding.

Where the Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID100X700S Is Used
Excavator Linkage Control
Drives synchronized dual-tool mechanisms on heavy equipment with equal push and pull force, leveraging the robust 100 mm bore for reliable actuation under harsh construction conditions.
Crane Load Positioning
Uses the rear exiting rod to mount a sensor cam for precise stroke feedback, ensuring accurate positioning of construction materials without rotational drift.
Concrete Pump Actuation
Handles heavy-duty valve gating on concrete machinery, utilizing the equal both-ways force to manage dense material flow reliably in demanding environments.
Replacing the Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID100X700S with the B04-SAID100X700S
To replace the discontinued B04-SID100X700S, use the SAID100X700S, which preserves the ISO 15552 mounting interface, 700 mm stroke, G1/2 port, and equal both-ways force. Size both directions by checking neighboring bores (80 mm or 125 mm) if force margins need adjustment, ensuring the equal push/pull rating meets your load. A double-rod design is right when you need anti-rotation, dual tool driving, or a back rod for sensor cams. Mounting options include FA, LB, and TC. The -S suffix indicates a piston magnet for CS1-B/DS1-B switches. For this 700 mm stroke, add external guides to prevent rod bending and manage side loads.
Replacement checklist
- ✓ Same ISO 15552 interface → B04-SAID100X700S
- ✓ 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-SID100X700S FAQ
Yes, the B04-SID100X700S is discontinued. The exact drop-in replacement is the SAID100X700S. The B04- prefix simply marks it as the construction-machinery dedicated variant of the base SID100X700S. The SAID replacement shares the exact same ISO 15552 interface, 100 mm bore, 700 mm stroke, G1/2 port, and mounting dimensions.
Force is equal both ways due to the double-rod design: 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 safe working load is approximately 2209 N, allowing a vertical lift of about 188 kg with a 2:1 margin. It operates at 0.15-1.0 MPa with a speed of 30-800 mm/s.
