Airtac B06-SCD Battery-Specific Standard Cylinder B06-SCD50X125
The AirTAC Airtac B06-SCD Battery-Specific Standard Cylinder B06-SCD50X125 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, 125mm stroke, PT1/4 ports and adjustable end cushioning.

About the Airtac B06-SCD Battery-Specific Standard Cylinder B06-SCD50X125
The B06-SCD50X125 is an AirTAC double-acting, double-rod cylinder where the B06- prefix designates it as a battery-manufacturing dedicated variant of the standard SCD50X125. Mechanically, it shares the exact same physical specifications, delivering an identical push and pull force of 1154 N at 0.7 MPa. The through-rod design provides excellent anti-rotation characteristics and allows tooling to be mounted on both ends.
Equipped with a Ø20 mm piston rod on both sides and PT1/4 ports, this unit features adjustable cushions with a 21 mm length to decelerate the piston smoothly at stroke ends. The retracted body length is based on an A(SCD) dimension of 207 mm, making it slightly longer than a single-rod SC equivalent. It operates effectively between -20 and +70 C using the standard TPU seal.
Airtac B06-SCD Battery-Specific Standard Cylinder B06-SCD50X125 Technical Specifications
| Model | Airtac B06-SCD Battery-Specific Standard Cylinder B06-SCD50X125 |
|---|---|
| Series | SCD double-rod tie-rod cylinder |
| Bore size | Ø50 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, 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-SCD50X125 Is Used
Cell Stacking Transfer
Ideal for battery cell stacking lines where the dual rods prevent rotation during precise electrode placement and shuttle movements.
Module Shuttle Conveyor
Provides symmetric two-sided actuation for pushing battery modules between conveyor belts without inducing asymmetric bearing wear.
Tab Welding Positioner
Carries welding tooling on the front rod while using the rear rod extension to mount a stroke-end sensor flag for precise tab alignment.
Is the Airtac B06-SCD Battery-Specific Standard Cylinder B06-SCD50X125 the Right Cylinder?
Choose this 50 mm bore when your battery assembly line requires 825 N of thrust each way at 0.5 MPa. If your tabbing or stacking process needs less force, step down to the 40 mm bore (528 N at 0.5 MPa); for heavier pack manipulation, step up to the 63 mm bore (1402 N at 0.5 MPa). A single-rod SC cylinder is preferable if you only need one-sided actuation, while a true guided cylinder is recommended for absorbing heavy lateral loads without deflecting the rod.
To guarantee a correct replacement, match the 50 mm bore, 125 mm stroke, PT1/4 port thread, basic mounting style, and confirm whether a magnetic piston (-S) is needed for position sensing. Note that the adjustable air cushion only decelerates the piston near the end of travel; it does not lock or hold the load. If the cell handling mechanism must maintain its position without live air pressure, an external mechanical lock or pilot-operated check valve is required.
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-SCD50X125 FAQ
The B06- prefix indicates this is an AirTAC battery-manufacturing dedicated cylinder. It is mechanically identical to the standard SCD50X125, offering the same 1154 N equal push and pull force at 0.7 MPa, but is designated for battery cell, module, and pack assembly applications.
The double-rod design ensures the push and pull forces are identical (825 N at 0.5 MPa) because the rod area is subtracted from both chambers. It also provides better rod guidance, anti-rotation stability for precision tasks, and a rear rod protrusion for mounting sensors or secondary tooling.
