Airtac B06-SCD Battery-Specific Standard Cylinder B06-SCD50X25
The AirTAC Airtac B06-SCD Battery-Specific Standard Cylinder B06-SCD50X25 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-SCD50X25
The B06-SCD50X25 is an AirTAC double-acting, double-rod cylinder where the B06- prefix designates it for battery-manufacturing lines, mechanically identical to the standard SCD50X25. The through-rod design yields identical thrust in both directions, delivering 825 N of push and pull force at 0.5 MPa (1484 N at 0.9 MPa). This symmetric output is ideal for compact cell-stacking and tabbing tasks.
With a short 25 mm stroke, the Ø20 mm piston rod exits both end caps to provide anti-rotation stability and a rear mounting point for tooling. The body length A(SCD) is 207 mm, and adjustable cushions at both ends ensure smooth deceleration. Note that cushions only slow the piston; an external brake or pilot check valve is required to hold a load without live air pressure.
Airtac B06-SCD Battery-Specific Standard Cylinder B06-SCD50X25 Technical Specifications
| Model | Airtac B06-SCD Battery-Specific Standard Cylinder B06-SCD50X25 |
|---|---|
| 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-SCD50X25 Is Used
Cell Stacking Press
Provides equal 825 N clamping and retraction force to align and press battery cells without rotational drift during stacking operations.
Tab Welding Shuttle
The through-rod allows a rear sensor flag to track the 25 mm travel precisely while moving battery tabs into the welding head.
Module Pick-and-Place
Dual rod ends support symmetrical tooling for picking and placing battery modules, ensuring balanced bearing wear over continuous cycles.
Is the Airtac B06-SCD Battery-Specific Standard Cylinder B06-SCD50X25 the Right Cylinder?
Choose this 50 mm bore when a battery-handling fixture needs equal force extending and retracting within a tight 25 mm window. If your module-transfer station requires less thrust, step down to a 40 mm bore offering 528 N at 0.5 MPa; for heavier pack manipulation, step up to a 63 mm bore providing 1402 N. Because the stroke is brief, rod bending is minimal, but verify side-load limits if guiding heavy battery trays.
If your application only requires one-sided actuation, the single-rod AirTAC SC series saves space and weight. For exact drop-in replacement of an SCD50X25, match the 50 mm bore, 25 mm stroke, PT1/4 port thread, basic mounting, and confirm whether a magnetic sensor ring (-S) is needed.
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-SCD50X25 FAQ
The B06- prefix indicates this cylinder is part of AirTAC's battery-manufacturing dedicated line. The B06-SCD50X25 is mechanically identical to the standard SCD50X25, featuring the same 50 mm bore, 25 mm stroke, and 825 N equal push/pull force at 0.5 MPa.
A double-rod cylinder provides equal push and pull forces because the rod area is subtracted from both chambers. It also offers better anti-rotation resistance and allows rear-end tooling or sensor mounting, which is critical for compact battery assembly stations.
