Airtac B06-SCD Battery-Specific Standard Cylinder B06-SCD63X125
The AirTAC Airtac B06-SCD Battery-Specific Standard Cylinder B06-SCD63X125 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. Ø63mm bore, 125mm stroke, PT1/4 ports and adjustable end cushioning.

About the Airtac B06-SCD Battery-Specific Standard Cylinder B06-SCD63X125
The B06-SCD63X125 is an AirTAC double-acting, double-rod cylinder where the B06- prefix designates it as a battery-manufacturing dedicated variant of the standard SCD63X125, sharing identical mechanical specifications. Because the piston rod passes through both end caps, the effective area is symmetrical, generating an equal push and pull force of 1402 N at 0.5 MPa (1962 N at 0.7 MPa). This equal bidirectional output is essential for battery cell stacking and tab welding operations requiring consistent pressure in both travel directions.
Equipped with a Ø20 mm rod protruding from both ends and a PT1/4 port, this unit features an adjustable cushion length of 28 mm to smoothly decelerate the payload near stroke limits. The retracted body length A(SCD) is 210 mm, which is longer than a comparable single-rod SC cylinder due to the through-rod design. This symmetric layout improves bearing load distribution and provides better anti-rotation characteristics for precision handling tasks.
Airtac B06-SCD Battery-Specific Standard Cylinder B06-SCD63X125 Technical Specifications
| Model | Airtac B06-SCD Battery-Specific Standard Cylinder B06-SCD63X125 |
|---|---|
| Series | SCD double-rod tie-rod cylinder |
| Bore size | Ø63 mm |
| Rod diameter | Ø20 mm (both ends) |
| Stroke | 125 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, 28 mm |
| Max stroke | Up to 1500 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 (Ø63mm, double rod)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1402 N | 1402 N |
| 0.7 MPa | 1962 N | 1962 N |
| Max (@1.0 MPa) | 286 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-SCD63X125 Is Used
Cell Stacking Press
Applies equal 1402 N clamping force in both directions to align and press battery cell layers without shifting, utilizing the through-rod for symmetrical bearing loading.
Dual-Sided Shuttle Transfer
Transfers battery modules between stations with tooling mounted on both rod ends, ensuring synchronous operation and preventing rotation during the 125 mm travel.
Tab Welding Positioner
Holds battery tabs securely against welding electrodes using consistent bidirectional thrust, with the rear rod available to mount a mechanical stopper or stroke limit flag.
Is the Airtac B06-SCD Battery-Specific Standard Cylinder B06-SCD63X125 the Right Cylinder?
Choose this 63 mm bore when your battery assembly line needs 1402 N of thrust each way at 0.5 MPa. If your module handling requires less force, stepping down to a 50 mm bore yields 825 N each way, while moving up to an 80 mm bore provides 2268 N for heavier pack manipulation. A single-rod SC cylinder is preferable if you only need unidirectional force and want a shorter footprint, but the SCD through-rod is superior when you need to mount tooling or a sensor flag on the rear side.
To replace this unit, match the 63 mm bore, 125 mm stroke, PT1/4 port thread, basic mounting style, and non-magnet configuration. For strokes of 300 mm or longer, the extended unsupported rod is susceptible to bending under side loads; in such cases, an external guide rail or a fully guided cylinder should be integrated to maintain alignment and prevent premature seal wear.
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-SCD63X125 FAQ
The B06- prefix indicates this is an AirTAC battery-manufacturing dedicated cylinder. It is mechanically identical to the standard SCD63X125, offering the same 1402 N equal push/pull force at 0.5 MPa, PT1/4 port, and Ø20 mm double rod, simply designated for battery industry applications.
No, the 28 mm adjustable cushion only decelerates the piston near the stroke ends to reduce impact. If a battery module or load must be held in position without live air pressure, a mechanical lock, external rod brake, or pilot-operated check valve must be used, as the cylinder will drift when pressure is lost.
