This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement B04-SAID63X600, with the same bore, stroke, output force, port and mounting, so it fits the same application. 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-SID63X600
The AirTAC Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID63X600 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø63mm bore and 600mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the B04-SAID63X600, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID63X600
The AirTAC B04-SID63X600 is a double-acting, double-rod ISO 15552 cylinder where a rod exits both ends, generating equal force in both directions (1402 N @0.5 MPa). The B04- prefix designates this as a construction-machinery dedicated variant; mechanically, it is identical to the standard SID63X600, featuring a 63mm bore, G3/8 port, and M16x1.5 rod thread. This legacy model is discontinued, and the direct replacement is the SAID63X600, which reuses the exact same ISO 15552 mounting interface and port size.
Because the piston has two rods, the effective area is identical on both faces, yielding equal push and pull forces (1962 N @0.7 MPa). This configuration provides inherent anti-rotation properties and allows the rear rod to drive a secondary mechanism or sensor cam. The SAID upgrade also introduces a two-piece Y-shaped piston seal for lower start-up pressure and longer life. Note that this non-magnetic SKU cannot accept position sensors.

Where the Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID63X600 Is Used
Excavator Linkage Actuation
Drives synchronized secondary linkage arms on heavy equipment where equal push and pull force prevents sagging during bidirectional construction movements.
Crusher Feed Transfer
Shifts heavy rock aggregate gates on material handling lines, utilizing the double-rod's inherent anti-rotation properties to resist uneven jaw loads.
Loader Attachment Sync
Operates dual-tool attachments on construction loaders, using the rear rod extension to mirror positioning cues without requiring a second actuator.
Replacing the Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID63X600 with the B04-SAID63X600
To replace the discontinued B04-SID63X600, use the SAID63X600; it is a direct swap retaining the 63mm bore, 600mm stroke, G3/8 port, and ISO 15552 mounting dimensions. When sizing, remember the double-rod design yields equal force both ways (1402 N @0.5 MPa), so if upgrading to a larger bore for more capacity, the 80mm bore provides 2268 N. A double-rod cylinder is selected when equal push/pull force, anti-rotation stability, or dual-end tooling is required. You can reuse FA, LB, or TC mounts. Since this SKU lacks the -S magnet, it cannot use magnetic switches. For the 600mm stroke, external guides are recommended to prevent rod bending and manage side loads.
Replacement checklist
- ✓ Same ISO 15552 interface → B04-SAID63X600
- ✓ 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-SID63X600 FAQ
Yes, the B04-SID63X600 is discontinued. The direct replacement is the SAID63X600. The B04- prefix simply marks it as a construction-machinery dedicated variant, so the SAID63X600 matches its 63mm bore, 600mm stroke, G3/8 port, and ISO 15552 mounting exactly.
As a double-rod cylinder, force is equal both ways: 1402 N @0.5 MPa, 1962 N @0.7 MPa, and 2523 N @0.9 MPa. The air port is G3/8. Note that air cushions only decelerate near stroke end; for load holding on air loss, use an external rod lock or the SAIL/BSAI variants.
