Airtac B04-SCD Specialized Standard Cylinder for Construction Machinery B04-SCD63X600
The AirTAC Airtac B04-SCD Specialized Standard Cylinder for Construction Machinery B04-SCD63X600 is a genuine double-acting DOUBLE-ROD air cylinder: the Ø20mm piston rod extends from BOTH end caps, giving equal effective area — and therefore equal force — in push and pull. Ø63mm bore, 600mm stroke, PT1/4 ports and adjustable end cushioning.

About the Airtac B04-SCD Specialized Standard Cylinder for Construction Machinery B04-SCD63X600
The B04-SCD63X600 is AirTAC's construction-machinery dedicated variant of the standard SCD63X600 double-rod cylinder. The B04- prefix designates it for heavy-equipment builders, but mechanically it is identical to the base model, offering the same robust tie-rod construction and exact specifications.
Featuring a 63 mm bore and 600 mm stroke, this double-acting cylinder provides 1402 N of equal push and pull force at 0.5 MPa. A Ø20 mm piston rod passes through both end caps, yielding identical thrust in both directions and improving anti-rotation characteristics. It includes adjustable cushions with a 28 mm length and operates at speeds of 30-800 mm/s.
Airtac B04-SCD Specialized Standard Cylinder for Construction Machinery B04-SCD63X600 Technical Specifications
| Model | Airtac B04-SCD Specialized Standard Cylinder for Construction Machinery B04-SCD63X600 |
|---|---|
| Series | SCD double-rod tie-rod cylinder |
| Bore size | Ø63 mm |
| Rod diameter | Ø20 mm (both ends) |
| Stroke | 600 mm |
| Rod configuration | Double rod — rod through both caps |
| Acting type | Double acting |
| Port size | PT1/4 |
| Rod thread | M16×1.5 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 30 – 800 mm/s |
| Cushion | Adjustable, 28 mm |
| Max stroke | Up to 1500 mm |
Specifications follow the official AirTAC SCD (double-rod) datasheet. Because the rod runs through both caps, the effective area is (bore² − rod²) in both directions. Confirm against the product label before installation. Thread options: PT (standard) / G.
Theoretical Output Force (Ø63mm, double rod)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1402 N | 1402 N |
| 0.7 MPa | 1962 N | 1962 N |
| Max (@1.0 MPa) | 286 kgf | |
Push and pull are EQUAL on a double-rod cylinder — both chambers lose the rod area, so effective area = (bore² − rod²) each way. Actual usable force is lower than theoretical due to friction and back-pressure; size with a safety margin.

Where the Airtac B04-SCD Specialized Standard Cylinder for Construction Machinery B04-SCD63X600 Is Used
Excavator Panel Shuttling
Drives heavy cabin panels or access covers on construction equipment where equal force is needed in both extend and retract motions.
Dual-Tool Transfer
Mounts tooling on both rod ends to alternately push and pull components through a machining station without reversing the load.
Non-Rotating Pusher
The through-rod design provides better resistance to twist compared to a single rod, ensuring stable pushing of heavy machinery parts.
Is the Airtac B04-SCD Specialized Standard Cylinder for Construction Machinery B04-SCD63X600 the Right Cylinder?
Choose this 63 mm bore when an application requires balanced 1402 N thrust both ways along with a long 600 mm stroke. If your machine needs less force, stepping down to a 50 mm bore yields 825 N; if more power is required, an 80 mm bore provides 2268 N. For jobs that do not require rear-side tooling or symmetric loading, a single-rod SC cylinder is a lighter, more compact alternative.
Because this model features a 600 mm stroke, the extended unsupported rod is susceptible to bending under heavy side loads. Use an external guide rail or select a fully guided cylinder to prevent rod damage. Replacements must match the 63 mm bore, 600 mm stroke, PT1/4 port thread, basic mounting style, and lack of a magnetic sensor.
Double-rod checklist
- ✓ Need equal force / speed both directions?
- ✓ Rear rod for tooling, stopper or sensor flag?
- ✓ Better rod guidance / anti-rotation?
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Keep BOTH rod ends clear of side load and interference.
- check Adjust end cushion screws for smooth stops.
- check Use SCD mounting accessory (FA / LB / TC / TCM1).
- check Installation by qualified personnel per AirTAC docs.
Airtac B04-SCD Specialized Standard Cylinder for Construction Machinery B04-SCD63X600 FAQ
The B04- prefix indicates this is AirTAC's construction-machinery dedicated line. It is mechanically identical to the standard SCD63X600, featuring the exact same 63 mm bore, 600 mm stroke, and physical specifications.
The double-rod design provides identical 1402 N push and pull force at 0.5 MPa because the rod area is subtracted from both chambers. It also allows mounting tooling or a sensor flag on the rear rod and offers better anti-rotation stability than a single-rod cylinder.
