Airtac B06-SCD Battery-Specific Standard Cylinder B06-SCD50X400
The AirTAC Airtac B06-SCD Battery-Specific Standard Cylinder B06-SCD50X400 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, 400mm stroke, PT1/4 ports and adjustable end cushioning.

About the Airtac B06-SCD Battery-Specific Standard Cylinder B06-SCD50X400
The B06-SCD50X400 is AirTAC's battery-manufacturing dedicated variant of the SCD50X400 double-acting, double-rod cylinder. The B06- prefix designates its use in cell, module, and pack assembly lines, though mechanically it is identical to the standard model. A 50 mm bore and 400 mm stroke provide 825 N of equal thrust in both directions at 0.5 MPa.
Because the Ø20 mm piston rod passes through both end caps, push and pull forces remain perfectly balanced. This through-rod architecture offers superior anti-rotation characteristics and allows tooling to be mounted on the rear side. The cylinder features a 207 mm body length A(SCD) and adjustable cushions with a 21 mm stroke length to decelerate loads smoothly at the ends.
Airtac B06-SCD Battery-Specific Standard Cylinder B06-SCD50X400 Technical Specifications
| Model | Airtac B06-SCD Battery-Specific Standard Cylinder B06-SCD50X400 |
|---|---|
| Series | SCD double-rod tie-rod cylinder |
| Bore size | Ø50 mm |
| Rod diameter | Ø20 mm (both ends) |
| Stroke | 400 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-SCD50X400 Is Used
Battery Cell Shuttle
Transfers battery cells between processing stations with equal push and pull force, ensuring stable and symmetrical movement.
Dual-Sided Tabbing
Carries welding or tabbing tooling on both rod ends to actuate from opposite sides simultaneously, reducing cycle time.
Non-Rotating Press
Uses the through-rod design to prevent rotation during delicate module alignment and light pressing tasks.
Is the Airtac B06-SCD Battery-Specific Standard Cylinder B06-SCD50X400 the Right Cylinder?
Choose this 50 mm bore when an application demands 825 N of symmetrical force each way, such as synchronizing two sides of a battery handling shuttle. If your battery stacking mechanism requires less force, stepping down to a 40 mm bore yields 528 N. If you need more clamping power for pack pressing, the 63 mm bore provides 1402 N. For tasks needing only one-sided actuation, the single-rod AirTAC SC series is more compact.
To replace this unit, match the 50 mm bore, 400 mm stroke, PT1/4 port thread, basic mounting, and no magnet. Since the 400 mm stroke creates a long unsupported rod, minimize side loading by using an external guide rail or a proper guided cylinder to prevent rod bending.
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-SCD50X400 FAQ
The B06- prefix indicates this is a battery-manufacturing dedicated cylinder. It is mechanically identical to the standard AirTAC SCD50X400, featuring the same 50 mm bore, 400 mm stroke, and 825 N equal push/pull force at 0.5 MPa.
No. The adjustable cushion only decelerates the piston near the stroke end and does not act as a brake. If a battery handling load must be held without live air pressure, you must use an external mechanical lock, rod brake, or pilot-operated check valve.
