Airtac B06-SCD Battery-Specific Standard Cylinder B06-SCD40X250
The AirTAC Airtac B06-SCD Battery-Specific Standard Cylinder B06-SCD40X250 is a genuine double-acting DOUBLE-ROD air cylinder: the Ø16mm piston rod extends from BOTH end caps, giving equal effective area — and therefore equal force — in push and pull. Ø40mm bore, 250mm stroke, PT1/4 ports and adjustable end cushioning.

About the Airtac B06-SCD Battery-Specific Standard Cylinder B06-SCD40X250
The B06-SCD40X250 is an AirTAC double-acting, double-rod cylinder built for battery manufacturing environments. The B06- prefix marks this as a battery-dedicated variant of the SCD40X250, meaning it is mechanically identical to the standard model. A 40mm bore and 250mm stroke provide 739 N of thrust and retraction force at 0.7 MPa, ensuring perfectly symmetric motion for cell stacking or tab handling.
Because the 16mm piston rod passes through both end caps, the effective pressure area is identical in both directions. This configuration yields equal force and speed while allowing tooling to mount on the rear rod. The body length A(SCD) is 191 mm, and adjustable cushions at both ends provide 21 mm of deceleration to protect sensitive battery components from end-of-stroke impact.
Airtac B06-SCD Battery-Specific Standard Cylinder B06-SCD40X250 Technical Specifications
| Model | Airtac B06-SCD Battery-Specific Standard Cylinder B06-SCD40X250 |
|---|---|
| Series | SCD double-rod tie-rod cylinder |
| Bore size | Ø40 mm |
| Rod diameter | Ø16 mm (both ends) |
| Stroke | 250 mm |
| Rod configuration | Double rod — rod through both caps |
| Acting type | Double acting |
| Port size | PT1/4 |
| Rod thread | M12×1.25 |
| 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 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 (Ø40mm, double rod)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 528 N | 528 N |
| 0.7 MPa | 739 N | 739 N |
| Max (@1.0 MPa) | 108 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-SCD40X250 Is Used
Cell Stacking Transfer
Equal push and pull force ensures precise, balanced movement when shifting battery cell layers into stacking fixtures.
Dual-End Shuttle Table
The through-rod design allows mounting a secondary tooling stopper on the rear side to actuate a shuttle mechanism from both ends.
Tab Welding Clamp
Provides non-rotating, symmetric clamping pressure for battery tab welding, with the 16mm rod maintaining rigidity on both ends.
Is the Airtac B06-SCD Battery-Specific Standard Cylinder B06-SCD40X250 the Right Cylinder?
Choose this 40mm bore when an application demands 528 N of equal force both ways at 0.5 MPa. If your battery line requires less force, stepping down to a 32mm bore yields 345 N; if you need heavier pack manipulation, a 63mm bore provides 1402 N. A single-rod SC cylinder is preferable if rear tooling or anti-rotation is unnecessary, while extreme side loads require a true guided cylinder rather than relying on the through-rod.
For a direct replacement, match the 40mm bore, 250mm stroke, PT1/4 port thread, basic mounting, and non-magnet configuration. With a 250mm stroke, the unsupported rod is susceptible to bending under offset loads; use an external guide rail to maintain alignment and prevent seal wear.
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-SCD40X250 FAQ
The B06- prefix designates this as a cylinder dedicated to battery manufacturing lines. It is mechanically identical to the standard SCD40X250, offering the same 40mm bore, 250mm stroke, and 739 N force at 0.7 MPa, with no changes to seals or dimensions.
A double-rod cylinder provides identical push and pull force (528 N at 0.5 MPa here) because the 16mm rod area is subtracted from both chambers. It also offers better rod guidance, resistance to rotation, and a rear rod extension for mounting secondary tooling or sensors.
