Airtac B06-SCD Battery-Specific Standard Cylinder B06-SCD40X800
The AirTAC Airtac B06-SCD Battery-Specific Standard Cylinder B06-SCD40X800 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, 800mm stroke, PT1/4 ports and adjustable end cushioning.

About the Airtac B06-SCD Battery-Specific Standard Cylinder B06-SCD40X800
The B06-SCD40X800 is AirTAC's battery-manufacturing dedicated variant of the standard SCD40X800 double-rod cylinder. The B06- prefix simply designates its intended use in cell, module, and pack assembly lines; mechanically, it is identical to the base model. Featuring a 40mm bore and 800mm stroke, it delivers an equal push and pull force of 739N at 0.7 MPa, making it ideal for synchronized two-sided actuation.
Because the piston rod passes through both end caps, this cylinder provides superior rod guidance and anti-rotation characteristics compared to a single-rod design. It features a Ø16mm rod on both ends, PT1/4 ports, and an adjustable cushion length of 21mm to decelerate the piston smoothly at stroke ends. The retracted body length is based on the SCD standard A dimension of 191mm, which is longer than an equivalent single-rod SC cylinder.
Airtac B06-SCD Battery-Specific Standard Cylinder B06-SCD40X800 Technical Specifications
| Model | Airtac B06-SCD Battery-Specific Standard Cylinder B06-SCD40X800 |
|---|---|
| Series | SCD double-rod tie-rod cylinder |
| Bore size | Ø40 mm |
| Rod diameter | Ø16 mm (both ends) |
| Stroke | 800 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-SCD40X800 Is Used
Battery Cell Stacking
Drives precision stacking plates in prismatic cell assembly, using the dual rods to keep pressure perfectly balanced during electrode layering.
Module Shuttle Transfer
Moves battery modules between welding stations on a transfer line, leveraging the equal push/pull force to maintain consistent indexing speed.
Non-Rotating Tab Welder
Actuates a tab welding head where the through-rod prevents rotational drift, ensuring the welding tip hits the battery terminal squarely.
Is the Airtac B06-SCD Battery-Specific Standard Cylinder B06-SCD40X800 the Right Cylinder?
Choose this 40mm bore when your battery-handling fixture requires exactly 528N of thrust each way at 0.5 MPa. If your application needs less force, stepping down is not an option in this series, but stepping up to a 50mm bore yields 825N at 0.5 MPa. For a 800mm stroke, the long unsupported rod is susceptible to bending under side loads; always use an external linear guide or a dedicated guided cylinder if heavy off-center tooling is mounted. If you only need one-sided actuation, a standard single-rod AirTAC SC cylinder will save space and cost.
To replace this unit, match all five points: 40mm bore, 800mm stroke, PT1/4 port thread, basic mounting (or an SCD-compatible accessory like F-SC40LB or F-SC40TC), and the magnet option (-S if required). Note that an SCD cylinder will drift if air pressure is lost; a mechanical lock or external rod brake is required to hold a load safely without live pressure.
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-SCD40X800 FAQ
The B06- prefix indicates this is an AirTAC cylinder dedicated to battery-manufacturing applications. It is mechanically identical to the standard SCD40X800, offering the same 40mm bore, 800mm stroke, and 739N equal push/pull force at 0.7 MPa.
A double-rod cylinder provides identical push and pull forces (739N both ways at 0.7 MPa here) because the rod area is subtracted from both chambers. The through-rod also offers better anti-rotation stability and allows you to mount tooling or a sensor flag on the rear side.
