This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B04-SAID100X75S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B04-SAID100X75S 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-SID100X75S
The AirTAC Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID100X75S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 75mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the B04-SAID100X75S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID100X75S
The AirTAC B04-SID100X75S is a double-acting, double-rod ISO 15552 cylinder where the B04- prefix designates it as the construction-machinery dedicated variant of the base SID100X75S. Because a rod exits both ends, the piston uses the rod-side annular area for both directions, yielding equal push and pull force of 3681 N at 0.5 MPa, 5153 N at 0.7 MPa, and 6626 N at 0.9 MPa. It features a 100 mm bore, a G1/2 port, an M20x1.5 rod thread, and 36 mm adjustable air cushions at each end. This legacy model is discontinued and is fully replaced by the SAID100X75S.
The SAID100X75S drop-in replacement shares the exact ISO 15552 mounting interface, bore, stroke, and porting, while upgrading the piston seal to two Y-shaped one-way elements for lower start-up pressure and longer life. For design gains, the second rod prevents rotation and can drive two separate tools or carry a sensor cam. Based on the 3681 N force at 0.5 MPa, the safe working load is approximately 2209 N, translating to a vertical lift capacity of about 188 kg with a 2:1 margin. The -S suffix indicates a built-in piston magnet for legacy CS1-B/DS1-B switches.

Where the Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID100X75S Is Used
Excavator Linkage Control
Uses the equal both-ways force and anti-rotation properties to drive synchronized positioning arms on heavy construction equipment without twist.
Concrete Batch Gate
Employs the dual rods to push and pull an aggregate discharge gate with matching 5153 N force at 0.7 MPa in both directions.
Crane Block Alignment
Leverages the back rod as a sensor cam target to track positioning while maintaining a 2209 N safe working load for lateral guide adjustments.
Replacing the Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID100X75S with the B04-SAID100X75S
To replace the discontinued B04-SID100X75S, specify the SAID100X75S, which preserves the 75 mm stroke, 100 mm bore, G1/2 port, and FA, LB, or TC mounting footprints without machining changes. Size both directions by verifying the equal-both-ways force: if 5153 N at 0.7 MPa is insufficient, step up to the 125 mm bore, or drop to the 80 mm bore if 2268 N at 0.5 MPa is enough. A double-rod cylinder is the right choice when you need anti-rotation stability or synchronized actuation on both ends. Because the stroke is under 300 mm, side-load leverage is minimal, but always maintain guide alignment. For load holding, note that a standard cylinder drifts on air loss; use an external rod lock or the SAIL/BSAI lock variants for held loads.
Replacement checklist
- ✓ Same ISO 15552 interface → B04-SAID100X75S
- ✓ 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-SID100X75S FAQ
Yes, the B04-SID100X75S is discontinued. The exact drop-in replacement is the SAID100X75S. The B04- prefix simply marks it as the construction-machinery dedicated variant of the SID100X75S, and the SAID replacement matches its ISO 15552 interface, 100 mm bore, 75 mm stroke, G1/2 port, and mounting dimensions exactly.
It is a double-acting double-rod cylinder with equal force both ways: 3681 N at 0.5 MPa, 5153 N at 0.7 MPa, and 6626 N at 0.9 MPa. The bore is 100 mm, the air port is G1/2, the rod thread is M20x1.5, and it has 36 mm adjustable cushions. The safe working load is approximately 2209 N, allowing a 188 kg vertical lift with a 2:1 margin.
