Airtac B04-SCD Specialized Standard Cylinder for Construction Machinery B04-SCD100X600S
The AirTAC Airtac B04-SCD Specialized Standard Cylinder for Construction Machinery B04-SCD100X600S is a genuine double-acting DOUBLE-ROD air cylinder: the Ø25mm piston rod extends from BOTH end caps, giving equal effective area — and therefore equal force — in push and pull. Ø100mm bore, 600mm stroke, PT1/2 ports and adjustable end cushioning.

About the Airtac B04-SCD Specialized Standard Cylinder for Construction Machinery B04-SCD100X600S
The B04-SCD100X600S is an AirTAC double-acting, double-rod cylinder where the B04- prefix designates it as a construction-machinery dedicated variant of the standard SCD100X600S, meaning it is mechanically identical to the base model. A Ø25 mm piston rod passes through both end caps, yielding identical thrust in both directions at 3681 N at 0.5 MPa and a robust 6626 N at 0.9 MPa.
Equipped with a built-in magnet (-S), this unit allows CMSG, DMSG, or EMSG sensors to track piston position along the 600 mm stroke. The PT1/2 port and 29 mm adjustable cushions manage end-of-stroke energy, while the overall retracted length is governed by the 263 mm body length A(SCD), which is inherently longer than a single-rod SC equivalent due to the through-rod design.
Airtac B04-SCD Specialized Standard Cylinder for Construction Machinery B04-SCD100X600S Technical Specifications
| Model | Airtac B04-SCD Specialized Standard Cylinder for Construction Machinery B04-SCD100X600S |
|---|---|
| Series | SCD double-rod tie-rod cylinder |
| Bore size | Ø100 mm |
| Rod diameter | Ø25 mm (both ends) |
| Stroke | 600 mm |
| Rod configuration | Double rod — rod through both caps |
| Acting type | Double acting |
| Port size | PT1/2 |
| Rod thread | M20×1.5 |
| 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, 29 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 (Ø100mm, double rod)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3682 N | 3682 N |
| 0.7 MPa | 5154 N | 5154 N |
| Max (@1.0 MPa) | 751 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-SCD100X600S Is Used
Heavy Equipment Shuttling
Drives bidirectional transfer tables on construction machinery fixtures, utilizing the equal push and pull force to move heavy structural components smoothly.
Double-Tooling Actuation
Mounts a workpiece gripper on the front rod and a synchronized stopper or sensor flag on the rear rod, leveraging the through-rod design for compact machine integration.
Non-Rotating Pushers
Pushes heavy panels or molds from both sides in a concrete mold vibrator, where the dual-rod guidance provides better resistance to torsional twisting than standard cylinders.
Is the Airtac B04-SCD Specialized Standard Cylinder for Construction Machinery B04-SCD100X600S the Right Cylinder?
This 100 mm bore fits heavy-equipment applications needing high bidirectional force. If 3681 N is excessive, stepping down to the 80 mm bore yields 2268 N at 0.5 MPa; if more thrust is required, the 125 mm bore offers 5734 N. For tasks needing only one-sided pushing, the single-rod AirTAC SC100 is lighter and shorter. Remember that a double-rod provides better anti-rotation than a single rod but cannot replace a true guided cylinder under heavy side loads.
With a 600 mm stroke, the unsupported rod length increases bending susceptibility; use an external guide rail to prevent premature bearing wear. To replace this unit, match the 100 mm bore, 600 mm stroke, PT1/2 port, basic mounting, and the -S magnet. Note that the adjustable cushions only decelerate the piston near stroke end and will not hold a load if air pressure is lost—a mechanical lock or pilot check valve is required for position holding.
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-SCD100X600S FAQ
The B04- prefix indicates this is AirTAC's construction-machinery dedicated variant of the SCD100X600S. It is mechanically identical to the standard model, offering the same 100 mm bore, 600 mm stroke, and 3681 N equal push/pull force at 0.5 MPa.
The double-rod design provides identical 3681 N force in both directions, allows tooling to be mounted on both ends, and offers better anti-rotation characteristics. The built-in magnet also enables position sensing, which is critical for automated heavy-equipment cycles.
