This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B04-SAID32X160 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B04-SAID32X160 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-SID32X160
The AirTAC Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID32X160 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 160mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the B04-SAID32X160, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID32X160
The AirTAC B04-SID32X160 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 a construction-machinery dedicated variant, mechanically identical to the standard SID32X160 with a 32 mm bore, 160 mm stroke, G1/8 port, and M10x1.25 rod thread. This legacy model is discontinued and is directly replaced by the SAID32X160.
The SAID32X160 drop-in replacement retains the exact ISO 15552 interface, bore, stroke, and equal-both-ways force, while adding an upgraded piston seal with two Y-shaped one-way elements for lower start-up pressure and longer life. Because the second rod can drive two tools or carry a sensor cam while resisting rotation, double-rod designs excel in heavy-equipment frames. Based on the 345 N @0.5 MPa rating, the computed safe working load is 207 N, allowing a vertical lift of roughly 18 kg with a 2:1 margin. Note this non-magnetic SKU cannot accept switches, and air cushions only decelerate; use an external rod lock for load holding.

Where the Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID32X160 Is Used
Excavator Linkage Actuation
Drives dual opposing plates in heavy-equipment cabins with equal push and pull force, leveraging the anti-rotation properties of the double-rod design.
Synchronized Tool Carriers
Uses the rear rod extension to mount a secondary cam or mechanism on construction-machinery frames, maintaining precise alignment without extra guides.
Heavy-Equipment Clamp Shift
Shifts clamping assemblies equally in both directions within a compact 32 mm bore envelope, reusing standard ISO 15552 mounting brackets.
Replacing the Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID32X160 with the B04-SAID32X160
To replace the discontinued B04-SID32X160, specify the SAID32X160, which matches the 32 mm bore, 160 mm stroke, G1/8 port, and ISO 15552 mounting dimensions (Basic, FA, LB, TC, FTC, TCM1, TCM2) for a direct drop-in. When sizing both ways, verify the equal push/pull force of 345 N @0.5 MPa fits your load, or step up to the 40 mm bore (528 N @0.5 MPa) if more force is needed. Choose a double-rod cylinder when you need anti-rotation stability or must drive two mechanisms simultaneously. Because this SKU lacks the -S magnet, it cannot use magnetic sensors. For strokes of 300 mm or longer, carefully manage side-load alignment to prevent premature seal wear.
Replacement checklist
- ✓ Same ISO 15552 interface → B04-SAID32X160
- ✓ 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-SID32X160 FAQ
Yes, the B04-SID32X160 (construction-machinery dedicated variant of the SID32X160) is discontinued. The exact drop-in replacement is the SAID32X160. It shares the same ISO 15552 interface, 32 mm bore, 160 mm stroke, G1/8 port, and equal-both-ways force, but features an upgraded SAI piston seal for longer life.
As a double-acting double-rod cylinder, force is equal both ways: 345 N @0.5 MPa, 483 N @0.7 MPa, and 621 N @0.9 MPa. The bore is 32 mm with a G1/8 air port and M10x1.25 rod thread. The safe working load is approximately 207 N. It lacks a magnet for sensors, and the air cushions only decelerate; they will not hold a load without air pressure.
