This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B04-SAID32X150 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B04-SAID32X150 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-SID32X150
The AirTAC Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID32X150 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 150mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the B04-SAID32X150, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID32X150
The AirTAC B04-SID32X150 is a double-acting double-rod ISO 15552 cylinder where a rod exits both ends, ensuring push and pull force are equal at 345 N @0.5 MPa, 483 N @0.7 MPa, and 621 N @0.9 MPa. The B04- prefix marks this as AirTAC's construction-machinery dedicated variant of the base SID32X150, mechanically identical with a 32 mm bore, 150 mm stroke, 12 mm rod, M10x1.25 thread, G1/8 port, and 27 mm adjustable cushions. This legacy series is discontinued; the direct drop-in replacement is the SAID32X150, which reuses the exact ISO 15552 mounting interface and adds an upgraded two Y-shaped one-way piston seal for lower start-up pressure and longer life.
Because the rear rod can carry a sensor cam or drive a second tool while resisting rotation, the double-rod layout excels in heavy-equipment frames. Computed buyer insight: the safe working load is ~207 N (60% of the 345 N @0.5 MPa figure), yielding a vertical lift capacity of ~18 kg with a 2:1 margin. Note this SKU lacks the -S magnet and cannot accept a sensor. For load holding, the cushion only decelerates; use an external rod lock or SAIL/BSAI variant, as drift occurs on air loss.

Where the Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID32X150 Is Used
Excavator Linkage
Equal push/pull force actuates secondary heavy-equipment covers without rotational drift.
Crusher Tooling
The rear rod drives a secondary cam while the front rod operates the main jaw.
Loader Alignment
Dual rods resist side torque during construction-machinery panel alignment tasks.
Replacing the Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID32X150 with the B04-SAID32X150
To replace the discontinued B04-SID32X150, specify the SAID32X150—it is a drop-in match for the 32 mm bore, 150 mm stroke, G1/8 port, and ISO 15552 mounting (Basic, FA, LB, TC). Size both ways by checking equal force: this bore yields 345 N @0.5 MPa. If undersized, the neighboring 40 mm bore provides 528 N @0.5 MPa. Choose a double-rod cylinder when you need anti-rotation stability or a back rod to drive a second mechanism. Because this SKU lacks the -S magnet, sensing is impossible. For this 150 mm stroke, side-load alignment is acceptable, but for strokes >=300 mm, guide rails are recommended to prevent binding.
Replacement checklist
- ✓ Same ISO 15552 interface → B04-SAID32X150
- ✓ 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-SID32X150 FAQ
Yes, the B04-SID32X150 (construction-machinery dedicated SID32X150) is discontinued. The exact drop-in replacement is the SAID32X150. It shares the identical ISO 15552 interface, 32 mm bore, 150 mm stroke, and G1/8 port, while upgrading the piston seal to two Y-shaped one-way elements for longer life.
Force is equal both ways: 345 N @0.5 MPa, 483 N @0.7 MPa, and 621 N @0.9 MPa. The air port is G1/8, the rod is 12 mm with an M10x1.25 thread, and adjustable cushioning is 27 mm. The safe working load is ~207 N.
