This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement B04-SAID63X200, 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-SID63X200
The AirTAC Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID63X200 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø63mm bore and 200mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the B04-SAID63X200, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID63X200
The AirTAC B04-SID63X200 is a double-acting, double-rod ISO 15552 cylinder where the B04- prefix designates it as the construction-machinery dedicated variant of the base SID63X200, mechanically identical in every spec. A rod exits both ends on one piston, meaning both faces use the rod-side area and push/pull force is equal both ways (1402 N @0.5 MPa, 1962 N @0.7 MPa, 2523 N @0.9 MPa). It features a 63mm bore, G3/8 port, M16x1.5 rod thread, and 30mm adjustable cushions at each end. This legacy SID model is discontinued and the direct replacement is the SAID63X200.
The SAID upgrade introduces an improved piston seal using two Y-shaped one-way elements for low start-up pressure and long life, while reusing the exact ISO 15552 mounting interface. Because the second rod resists rotation and can drive a second tool simultaneously, double-rod designs excel in heavy equipment. Note this non-magnetic SKU cannot take a sensor switch.

Where the Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID63X200 Is Used
Excavator Linkage Actuation
Equal push/pull force drives dual-arm mechanisms on heavy construction equipment without stroke imbalance.
Crusher Feed Sync
The twin rods push and retract material gates simultaneously, ensuring timed feed flow in rock crushing.
Loader Mast Guide
Anti-rotation properties from the second rod keep mast alignment true under heavy vertical payload shifts.
Replacing the Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID63X200 with the B04-SAID63X200
To replace the discontinued B04-SID63X200, specify the SAID63X200—it is a direct match for the 63mm bore, 200mm stroke, G3/8 port, and ISO 15552 mounting (Basic, FA, LB, TC). When sizing both ways, verify the equal force (1402 N @0.5 MPa) handles your load; if more force is needed, step up to the 80mm bore, or drop to 50mm if less is required. A double rod is the right choice when you need anti-rotation stability or must drive two mechanisms at once. For strokes >=300mm, calculate side-load carefully to prevent binding. This SKU lacks the -S magnet, so it cannot support legacy CS1-B/DS1-B sensors. Finally, a plain cylinder drifts on air loss—the cushion only decelerates near stroke end—so for held loads use an external rod lock, pilot-operated check valve, or the SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → B04-SAID63X200
- ✓ 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-SID63X200 FAQ
Yes, the B04-SID63X200 is discontinued. The direct replacement is the SAID63X200. The B04- prefix simply marks it as the construction-machinery dedicated variant of the SID63X200; mechanically, all specs (63mm bore, G3/8 port, M16x1.5 thread) are identical. The SAID family uses an upgraded piston seal but retains the exact ISO 15552 mounting interface.
Because it is 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 bore is 63mm, the air port is G3/8, the rod thread is M16x1.5, and speed is 30-800 mm/s. It operates at 0.15-1.0 MPa with 30mm adjustable cushions at each end.
