Airtac B06-SCD Battery-Specific Standard Cylinder B06-SCD40X125S
The AirTAC Airtac B06-SCD Battery-Specific Standard Cylinder B06-SCD40X125S 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-SCD40X125S
The B06-SCD40X125S is an AirTAC double-acting, double-rod cylinder where the B06- prefix designates it as a battery-manufacturing dedicated variant; mechanically, it is identical to the standard SCD40X125S. The through-rod design yields perfectly symmetrical thrust, generating 739 N of force in both directions at 0.7 MPa.
Because the Ø16 mm piston rod exits both end caps, this unit provides superior anti-rotation characteristics and allows tooling to be mounted on the rear side. It includes a built-in magnet for position sensing, features a 21 mm adjustable cushion at stroke ends, and has a retracted body length A(SCD) of 191 mm.
Airtac B06-SCD Battery-Specific Standard Cylinder B06-SCD40X125S Technical Specifications
| Model | Airtac B06-SCD Battery-Specific Standard Cylinder B06-SCD40X125S |
|---|---|
| Series | SCD double-rod tie-rod cylinder |
| Bore size | Ø40 mm |
| Rod diameter | Ø16 mm (both ends) |
| 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-SCD40X125S Is Used
Battery Cell Stacking
Equal push and pull thrust ensures precise, balanced pressure when stacking electrode sheets during cell assembly.
Shuttle Transfer
The through-rod allows dual tooling mounting for loading and unloading battery modules from conveyor lines simultaneously.
Welding Tab Sensing
The built-in magnet pairs with CMSG sensors to confirm exact 125 mm stroke positioning for tab welding heads.
Is the Airtac B06-SCD Battery-Specific Standard Cylinder B06-SCD40X125S the Right Cylinder?
Select this 40 mm bore when an application demands exactly 528 N of thrust each way at 0.5 MPa. If your battery stacking mechanism requires less force, step down to the 32 mm bore (345 N at 0.5 MPa); if you need heavier tab welding pressure, step up to the 50 mm bore (825 N at 0.5 MPa). A single-rod SC cylinder is preferable if you only need one-sided actuation and want a shorter overall footprint.
To guarantee a correct drop-in replacement, verify five details: 40 mm bore, 125 mm stroke, PT1/4 port thread, basic mounting (or an SCD-compatible accessory like F-SC40LB), and the presence of the -S magnet. Note that the adjustable air cushions only decelerate the piston near end caps; they do not lock the load. If battery cell positioning must be maintained without live air pressure, fit an external rod brake or pilot-operated check valve.
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-SCD40X125S FAQ
The B06- prefix indicates this cylinder is part of AirTAC's battery-manufacturing dedicated line. It is mechanically identical to the standard SCD40X125S, offering the same 40 mm bore, 125 mm stroke, and 739 N force at 0.7 MPa.
The double-rod design provides identical 528 N push and pull force at 0.5 MPa, better rod guidance to prevent rotation, and a rear rod extension for mounting secondary tooling or sensor flags, which is critical for synchronized battery handling.
