Airtac B06-SCD Battery-Specific Standard Cylinder B06-SCD40X400
The AirTAC Airtac B06-SCD Battery-Specific Standard Cylinder B06-SCD40X400 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, 400mm stroke, PT1/4 ports and adjustable end cushioning.

About the Airtac B06-SCD Battery-Specific Standard Cylinder B06-SCD40X400
The B06-SCD40X400 is an AirTAC double-acting, double-rod cylinder where the B06- prefix designates it as a battery-manufacturing dedicated variant, mechanically identical to the standard SCD40X400. The through-rod design yields identical thrust in both directions, providing 528 N of push and pull force at 0.5 MPa, and 950 N at 0.9 MPa. This symmetry is essential for battery cell stacking and tab welding where both extension and retraction must move identical payloads.
Equipped with a Ø16 piston rod extending through both end caps, this unit provides enhanced anti-rotation characteristics and supports tooling on the rear side for synchronous operations. The 400 mm stroke operates at speeds of 30-800 mm/s, while adjustable cushions at both ends absorb impact energy over a 21 mm cushion length. Its retracted body length is based on an A(SCD) dimension of 191 mm, making the overall housing longer than a comparable single-rod SC cylinder.
Airtac B06-SCD Battery-Specific Standard Cylinder B06-SCD40X400 Technical Specifications
| Model | Airtac B06-SCD Battery-Specific Standard Cylinder B06-SCD40X400 |
|---|---|
| Series | SCD double-rod tie-rod cylinder |
| Bore size | Ø40 mm |
| Rod diameter | Ø16 mm (both ends) |
| Stroke | 400 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-SCD40X400 Is Used
Cell Stacking Transfer
Synchronizes double-sided pick-and-place heads for lithium-ion cell stacking, utilizing the equal push and pull force to maintain precise layer alignment without drift.
Module Shuttle Conveyor
Drives a bidirectional shuttle table for battery module indexing. The through-rod allows a rear-mounted mechanical stopper to define the exact retraction limit.
Tab Welding Clamp
Actuates a non-rotating welding clamp for battery tab joining. The dual-rod guidance ensures the electrode face remains perfectly parallel during the 400 mm travel.
Is the Airtac B06-SCD Battery-Specific Standard Cylinder B06-SCD40X400 the Right Cylinder?
Choose this 40 mm bore when your battery handling system requires 528 N of equal bidirectional force at 0.5 MPa. If your module transfer station needs less thrust, stepping down to the 32 mm bore provides 345 N each way. Conversely, heavier pack manipulation may require the 63 mm bore, which outputs 1402 N. If the application only drives a load in one direction, a standard single-rod AirTAC SC cylinder is a lighter, more compact alternative.
At 400 mm of stroke, the unsupported rod length increases susceptibility to bending under side loads. For optimal bearing life, guide the load externally or select a dedicated guided cylinder. To replace this unit, match the 40 mm bore, 400 mm stroke, PT1/4 port thread, basic mounting style, and confirm whether a magnetic piston (-S) is required for CMSG/DMSG sensor tracking.
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-SCD40X400 FAQ
The B06- prefix indicates this is a battery-manufacturing dedicated variant of the standard AirTAC SCD40X400. The physical specifications, dimensions, and force outputs remain exactly the same as the base SCD model; the prefix simply designates its optimized application context for battery production lines.
No, the adjustable cushion only decelerates the piston near the stroke ends over a 21 mm length and does not function as a locking brake. If your battery handling fixture must hold a vertical load without live air pressure, you must install an external rod brake, a mechanical lock, or a pilot-operated check valve.
