Airtac B06-SCD Battery-Specific Standard Cylinder B06-SCD50X300
The AirTAC Airtac B06-SCD Battery-Specific Standard Cylinder B06-SCD50X300 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. Ø50mm bore, 300mm stroke, PT1/4 ports and adjustable end cushioning.

About the Airtac B06-SCD Battery-Specific Standard Cylinder B06-SCD50X300
The B06-SCD50X300 is an AirTAC double-acting, double-rod cylinder where the B06- prefix designates it as a battery-manufacturing dedicated variant of the standard SCD50X300. Mechanically, it is identical to the base model, featuring a 50 mm bore and a 300 mm stroke. Because the piston rod passes through both end caps, the effective area is identical in both chambers, yielding an equal push and pull force of 825 N at 0.5 MPa.
This symmetric thrust is highly advantageous on battery cell stacking and module handling lines, where a rear rod can carry a secondary tool or sensor flag. The cylinder uses a Ø20 mm rod on both ends, features adjustable cushions with a 21 mm length, and has a body length A(SCD) of 207 mm. At a maximum operating pressure of 0.9 MPa, it generates 1484 N of thrust in either direction.
Airtac B06-SCD Battery-Specific Standard Cylinder B06-SCD50X300 Technical Specifications
| Model | Airtac B06-SCD Battery-Specific Standard Cylinder B06-SCD50X300 |
|---|---|
| Series | SCD double-rod tie-rod cylinder |
| Bore size | Ø50 mm |
| Rod diameter | Ø20 mm (both ends) |
| Stroke | 300 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, 21 mm |
| Max stroke | Up to 1200 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 (Ø50mm, double rod)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 825 N | 825 N |
| 0.7 MPa | 1155 N | 1155 N |
| Max (@1.0 MPa) | 168 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 B06-SCD Battery-Specific Standard Cylinder B06-SCD50X300 Is Used
Battery Cell Stacking
Provides equal push and pull force for precisely pressing and stacking battery cells, using the dual rods to maintain parallel tooling alignment.
Module Shuttle Transfer
Drives a bidirectional shuttle table for moving battery modules between assembly stations, utilizing the rear rod for a counterweight or stopper.
Non-Rotating Tab Welding
Holds welding tooling on both ends to prevent rod twist during battery tab welding operations, ensuring consistent electrode contact.
Is the Airtac B06-SCD Battery-Specific Standard Cylinder B06-SCD50X300 the Right Cylinder?
Select this 50 mm bore when an application demands 825 N of force both ways and a 300 mm stroke. If your battery assembly process requires less force, stepping down to a 40 mm bore provides 528 N each way. Conversely, if you need to move heavier battery packs, the 63 mm bore offers 1402 N. If the task only requires one-sided actuation, the single-rod AirTAC SC series is a simpler choice, while true high side-load conditions call for a dedicated guided cylinder rather than relying on the through-rod.
With a 300 mm stroke, the unsupported rod length increases, raising the risk of rod bending under offset loads. Use external guide rails to support the tooling and prevent premature bearing wear. For exact replacements, match the 50 mm bore, 300 mm stroke, PT1/4 port thread, basic mounting, and confirm whether a magnetic piston (-S) is required.
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 B06-SCD Battery-Specific Standard Cylinder B06-SCD50X300 FAQ
The B06- prefix indicates this is a battery-manufacturing dedicated variant of the standard AirTAC SCD50X300. It is mechanically identical to the base model, offering the same 50 mm bore, 300 mm stroke, and 825 N equal push/pull force at 0.5 MPa.
No, the adjustable cushion only decelerates the piston near the stroke ends and cannot lock or hold a load. If a battery module must be held without live air pressure, an external mechanical lock, rod brake, or pilot-operated check valve is required.
