Airtac B06-SCD Battery-Specific Standard Cylinder B06-SCD40X400S
The AirTAC Airtac B06-SCD Battery-Specific Standard Cylinder B06-SCD40X400S 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-SCD40X400S
The B06-SCD40X400S is AirTAC's battery-manufacturing dedicated variant of the standard SCD40X400S double-rod cylinder. The B06- prefix designates its use in cell, module, and pack assembly lines, but mechanically it is identical to the base model. It features a 40mm bore and a 400mm stroke.
Because this is a double-acting double-rod design, the Ø16mm piston rod passes through both end caps. This yields identical thrust in both directions at 528N at 0.5 MPa and 739N at 0.7 MPa. The extended 400mm stroke provides ample travel for tabbing, stacking, or shuttle transfers. The built-in magnet (-S) allows CMSG or DMSG sensors to track piston position along the 191mm body length A(SCD).

|---|---|
| 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-SCD40X400S Is Used
Cell Stacking Transfer
Moves battery cells precisely between stacking stations using equal push and pull force to maintain consistent indexing without rotational drift.
Module Shuttle Conveyor
Drives a dual-sided shuttle mechanism for battery module handling, using the rear rod extension to mount a secondary stopper or sensor flag.
Tab Welding Positioner
Positions battery tabs for laser welding with symmetrical bearing loads, ensuring smooth retraction even under high cycle counts.
Is the Airtac B06-SCD Battery-Specific Standard Cylinder B06-SCD40X400S the Right Cylinder?
Choose this 40mm bore when a battery-handling mechanism requires 739N of symmetrical force at 0.7 MPa. If your transfer line needs less thrust, stepping down to a 32mm bore provides 483N. If you need to move heavier battery modules, moving up to a 50mm bore yields 1154N. A single-rod SC cylinder is preferable if you only need one-sided actuation and want a shorter overall footprint.
At 400mm of stroke, the unsupported rod length increases. Avoid excessive side loads on the rod ends; use an external guide rail or a proper guided cylinder to prevent rod bending and premature bearing wear. To replace this unit, match the 40mm bore, 400mm stroke, PT1/4 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-SCD40X400S FAQ
The B06- prefix indicates this cylinder is part of AirTAC's battery-manufacturing dedicated line. The B06-SCD40X400S is mechanically identical to the standard SCD40X400S, offering the same 40mm bore, 400mm stroke, and 739N equal push/pull force at 0.7 MPa.
No, the push and pull forces are identical. Because the rod occupies area on both sides of the piston, the effective area is equal in both directions. This model generates 528N at 0.5 MPa and 739N at 0.7 MPa in both directions. Note that air pressure must be maintained to hold a load; the adjustable cushion only decelerates the piston at stroke end and does not act as a brake.
