Airtac B04-SCD Specialized Standard Cylinder for Construction Machinery B04-SCD32X150
The AirTAC Airtac B04-SCD Specialized Standard Cylinder for Construction Machinery B04-SCD32X150 is a genuine double-acting DOUBLE-ROD air cylinder: the Ø12mm piston rod extends from BOTH end caps, giving equal effective area — and therefore equal force — in push and pull. Ø32mm bore, 150mm stroke, PT1/8 ports and adjustable end cushioning.

About the Airtac B04-SCD Specialized Standard Cylinder for Construction Machinery B04-SCD32X150
The B04-SCD32X150 is an AirTAC construction-machinery dedicated double-rod cylinder, mechanically identical to the standard SCD32X150. The B04- prefix simply designates its readiness for heavy-equipment builders without altering any physical specs. As a double-acting, double-rod actuator, it delivers 483 N of equal push and pull force at 0.7 MPa.
Because the 12 mm rod passes through both end caps, thrust is symmetrical in both directions, reaching 621 N at 0.9 MPa. The 150 mm stroke is well within the 1000 mm maximum for this 32 mm bore. It features adjustable cushions (21 mm) and a 187 mm body length A(SCD), providing excellent anti-rotation stability for dual-tooling setups.
Airtac B04-SCD Specialized Standard Cylinder for Construction Machinery B04-SCD32X150 Technical Specifications
| Model | Airtac B04-SCD Specialized Standard Cylinder for Construction Machinery B04-SCD32X150 |
|---|---|
| Series | SCD double-rod tie-rod cylinder |
| Bore size | Ø32 mm |
| Rod diameter | Ø12 mm (both ends) |
| Stroke | 150 mm |
| Rod configuration | Double rod — rod through both caps |
| Acting type | Double acting |
| Port size | PT1/8 |
| Rod thread | M10×1.25 |
| 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, 21 mm |
| Max stroke | Up to 1000 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 (Ø32mm, double rod)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 346 N | 346 N |
| 0.7 MPa | 484 N | 484 N |
| Max (@1.0 MPa) | 70 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-SCD32X150 Is Used
Excavator Control Linkages
Drives symmetric push/pull mechanisms on compact construction machinery where equal force is needed in both directions.
Shuttle Transfer Stops
Uses the rear rod extension as a physical stopper or sensor target for material routing on heavy-equipment assembly lines.
Non-Rotating Pushers
The dual-rod design resists torsional twist better than single-rod units, ensuring precise actuation for mounted tooling.
Is the Airtac B04-SCD Specialized Standard Cylinder for Construction Machinery B04-SCD32X150 the Right Cylinder?
Choose this 32 mm bore when you need 483 N of thrust both ways on a compact piece of construction equipment. If your mechanism only requires force in one direction, the single-rod AirTAC SC32X150 is lighter and simpler. For heavy side loads, a dedicated guided cylinder is superior, as the through-rod provides extra guidance but is not a substitute for true linear bearings.
To replace this unit, match the 32 mm bore, 150 mm stroke, PT1/8 port, basic mounting, and lack of a magnet. At 150 mm stroke, side-load bending on the unsupported rod is moderate; use external guides if the load is heavy or off-center.
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-SCD32X150 FAQ
The B04- prefix indicates this is an AirTAC construction-machinery dedicated variant. It is mechanically identical to the standard SCD32X150, offering the same 483 N equal push/pull force and PT1/8 ports, with no changes to dimensions or seals.
A double-rod cylinder provides identical 483 N force in both directions because the 12 mm rod area is subtracted from both chambers. It also offers a rear rod for mounting tooling or sensors and better anti-rotation resistance than a single-rod cylinder.
