Airtac B06-SCD Battery-Specific Standard Cylinder B06-SCD40X350S
The AirTAC Airtac B06-SCD Battery-Specific Standard Cylinder B06-SCD40X350S 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, 350mm stroke, PT1/4 ports and adjustable end cushioning.

About the Airtac B06-SCD Battery-Specific Standard Cylinder B06-SCD40X350S
The B06-SCD40X350S is an AirTAC double-acting, double-rod cylinder engineered for battery-manufacturing lines. The B06- prefix marks this as a battery-dedicated variant of the SCD40X350S, meaning it is mechanically identical to the standard model but designated for cell, module, and pack assembly applications. The through-rod design yields identical 528 N thrust in both directions at 0.5 MPa.
Featuring a 40 mm bore and 350 mm stroke, this unit uses a Ø16 mm piston rod exiting both end caps. It includes a built-in magnet for CMSG/DMSG/EMSG sensor tracking along the 191 mm body length A(SCD). The adjustable cushions provide 21 mm of deceleration at stroke ends to protect precision tooling.
Airtac B06-SCD Battery-Specific Standard Cylinder B06-SCD40X350S Technical Specifications
| Model | Airtac B06-SCD Battery-Specific Standard Cylinder B06-SCD40X350S |
|---|---|
| Series | SCD double-rod tie-rod cylinder |
| Bore size | Ø40 mm |
| Rod diameter | Ø16 mm (both ends) |
| Stroke | 350 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-SCD40X350S Is Used
Battery Cell Stacking
Drives symmetric stacking mechanisms for prismatic battery cells, using the dual rods to maintain parallel pressure across the electrode sheets.
Module Transfer Shuttle
Powers a shuttle table that transfers battery modules between welding stations, leveraging the equal push and pull force for consistent cycle times.
Non-Rotating Tab Welder
Actuates a tab welding fixture where the rear rod carries a stopper flag, ensuring the front tooling hits the battery tabs without rotational drift.
Is the Airtac B06-SCD Battery-Specific Standard Cylinder B06-SCD40X350S the Right Cylinder?
This 40 mm bore provides 528 N both ways; step down to a 32 mm bore if you only need 345 N, or up to a 50 mm bore for 825 N. A single-rod SC cylinder is preferable if you only need one-sided actuation, while a true guided cylinder is better for heavy lateral loads. The 350 mm stroke is within the 1200 mm max standard stroke for this bore.
At 350 mm, the unsupported rod length increases susceptibility to bending under side loads. Use an external guide rail or a guided cylinder to maintain alignment and prevent premature seal wear. To replace this unit, match the 40 mm bore, 350 mm stroke, PT port thread, basic mounting, and the -S magnet option.
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-SCD40X350S FAQ
The B06- prefix indicates this is an AirTAC battery-manufacturing dedicated variant of the SCD40X350S. It is mechanically identical to the standard double-rod cylinder, offering the same 40 mm bore, 350 mm stroke, and 528 N equal push/pull force, but is designated for battery assembly lines.
No, the 21 mm adjustable cushion only decelerates the piston near the stroke ends to reduce impact. It does not lock or hold the load. If the battery assembly process requires position holding without live air pressure, you must use an external mechanical lock or pilot-operated check valve.
