Airtac B06-SCD Battery-Specific Standard Cylinder B06-SCD40X125
The AirTAC Airtac B06-SCD Battery-Specific Standard Cylinder B06-SCD40X125 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, 125mm stroke, PT1/4 ports and adjustable end cushioning.

About the Airtac B06-SCD Battery-Specific Standard Cylinder B06-SCD40X125
The B06-SCD40X125 is an AirTAC double-acting, double-rod cylinder where the B06- prefix designates it as a battery-manufacturing dedicated variant of the standard SCD40X125. Mechanically, it shares the exact same physical specs, delivering an equal push and pull force of 528 N at 0.5 MPa (739 N at 0.7 MPa). The through-rod design uses a 16 mm diameter rod on both ends, ensuring symmetric bearing loading and superior anti-rotation characteristics for precision tasks.
With a 125 mm stroke, this model features adjustable cushions with a 21 mm length to smoothly decelerate the piston at both ends. The overall retracted body length A(SCD) is 191 mm, which is longer than a single-rod SC cylinder of the same bore due to the rod protruding from both end caps. It operates on filtered air at 0.15-1.0 MPa with a speed range of 30-800 mm/s.

| Stroke | 125 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-SCD40X125 Is Used
Battery Cell Stacking
Provides equal force and non-rotating dual-side actuation for precisely aligning and stacking prismatic battery cells during module assembly.
Shuttle Transfer Tables
Drives symmetric transfer shuttles for moving battery trays between conveyor belts, utilizing the rear rod for external stopper mounting.
Tab Welding Clamps
Applies consistent 528 N clamping pressure on both extension and retraction to hold battery tabs firmly during ultrasonic welding processes.
Is the Airtac B06-SCD Battery-Specific Standard Cylinder B06-SCD40X125 the Right Cylinder?
Choose this 40 mm bore when an application requires 528 N of force in both directions simultaneously, such as synchronizing two-sided clamping or tabbing in battery module assembly. If your battery line needs less force, stepping down to a 32 mm bore provides 345 N each way. If higher thrust is required for heavy pack handling, moving up to a 50 mm bore yields 825 N. A single-rod SC cylinder is preferable if rear tooling or a symmetric load is unnecessary, while a fully guided cylinder should be selected for applications with severe lateral loads.
To replace this unit, match the 40 mm bore, 125 mm stroke, PT1/4 port thread, basic mounting, and no magnet. Since the stroke is 125 mm, side-load and rod bending on the unsupported ends are minimal but should still be managed with external guides if driving offset loads. Note that air pressure must be maintained to hold a load; the adjustable cushion only decelerates the piston and does not function as a mechanical brake or locking device.
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-SCD40X125 FAQ
The B06- prefix indicates this is a battery-manufacturing dedicated cylinder. It is mechanically identical to the standard AirTAC SCD40X125, meaning the bore, stroke, force, and port sizes are exactly the same. The prefix simply designates its optimized application context for cell, module, and pack assembly lines.
A double-rod cylinder provides identical push and pull forces (528 N at 0.5 MPa for this 40 mm bore) because the rod area is subtracted on both sides. The through-rod design offers better anti-rotation, symmetric bearing wear, and allows tooling or sensors to be mounted on the rear rod, which is critical for synchronized battery assembly operations.
