Airtac B06-SCD Battery-Specific Standard Cylinder B06-SCD50X25S
The AirTAC Airtac B06-SCD Battery-Specific Standard Cylinder B06-SCD50X25S is a genuine double-acting DOUBLE-ROD air cylinder: the Ø20mm piston rod extends from BOTH end caps, giving equal effective area — and therefore equal force — in push and pull. Ø50mm bore, 25mm stroke, PT1/4 ports and adjustable end cushioning.

About the Airtac B06-SCD Battery-Specific Standard Cylinder B06-SCD50X25S
The B06-SCD50X25S is an AirTAC double-acting, double-rod cylinder where the B06- prefix designates it as a battery-manufacturing dedicated variant, mechanically identical to the standard SCD50X25S. The through-rod design yields identical thrust in both directions, outputting 825 N at 0.5 MPa and 1484 N at 0.9 MPa.
Because the piston rod protrudes from both end caps, you gain superior anti-rotation characteristics and symmetric bearing loading for short-stroke battery stacking or tabbing tasks. This specific model includes a built-in magnet (the S suffix) allowing CMSG or DMSG sensors to track position, uses a PT1/4 port, and features a 20 mm rod on both ends with 21 mm adjustable cushions.
Airtac B06-SCD Battery-Specific Standard Cylinder B06-SCD50X25S Technical Specifications
| Model | Airtac B06-SCD Battery-Specific Standard Cylinder B06-SCD50X25S |
|---|---|
| Series | SCD double-rod tie-rod cylinder |
| Bore size | Ø50 mm |
| Rod diameter | Ø20 mm (both ends) |
| Stroke | 25 mm |
| Rod configuration | Double rod — rod through both caps |
| Acting type | Double acting |
| Port size | PT1/4 |
| Rod thread | M16×1.5 |
| 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 (Ø50mm, double rod)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 825 N | 825 N |
| 0.7 MPa | 1155 N | 1155 N |
| Max (@1.0 MPa) | 168 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-SCD50X25S Is Used
Battery Cell Stacking
Provides equal push and pull force for pressing and aligning battery cells during module stacking, ensuring precise symmetric movement.
Tabbing Shuttle Transfer
The through-rod allows mounting dual tooling or stopper flags on both sides, ideal for shuttling battery tabs between welding stations.
Position Verification
The built-in magnet enables CMSG/DMSG sensors to confirm exact end-of-stroke positioning on high-speed battery production lines.
Is the Airtac B06-SCD Battery-Specific Standard Cylinder B06-SCD50X25S the Right Cylinder?
Choose this 50 mm bore when your battery assembly cell requires balanced 825 N force both ways within a very compact 25 mm stroke. If your module handling demands less thrust, step down to the 40 mm bore (528 N at 0.5 MPa); for heavier pack manipulation, the 63 mm bore provides 1402 N. A single-rod SC cylinder is preferable if rear tooling is unnecessary, while extreme side loads require a true guided cylinder rather than relying solely on the through-rod.
For exact drop-in replacements, match the 50 mm bore, 25 mm stroke, PT1/4 thread, basic mounting, and the -S magnet. Note that the adjustable cushions decelerate the piston near stroke end but do not lock the load; a mechanical lock or pilot-operated check valve is required to hold a load without live air 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-SCD50X25S FAQ
The B06- prefix indicates this is a battery-manufacturing dedicated cylinder. Mechanically and dimensionally, it is identical to the standard AirTAC SCD50X25S, featuring the same 50 mm bore, 25 mm stroke, and double-rod construction.
A double-rod cylinder provides equal push and pull force (825 N at 0.5 MPa) because the rod area is subtracted from both chambers. The through-rod also offers better anti-rotation resistance and allows tooling to be mounted on both ends, which is critical for precision battery assembly.
