Airtac B06-SCD Battery-Specific Standard Cylinder B06-SCD50X250S
The AirTAC Airtac B06-SCD Battery-Specific Standard Cylinder B06-SCD50X250S 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, 250mm stroke, PT1/4 ports and adjustable end cushioning.

About the Airtac B06-SCD Battery-Specific Standard Cylinder B06-SCD50X250S
The B06-SCD50X250S is an AirTAC double-acting, double-rod cylinder where the B06- prefix designates it as a battery-manufacturing dedicated variant of the standard SCD50X250S. Mechanically identical to the base model, it features a 50 mm bore and 250 mm stroke. Because the piston rod passes through both end caps, the effective area is identical in both chambers, yielding an equal push and pull force of 825 N at 0.5 MPa. At the maximum 0.9 MPa operating pressure, this cylinder generates 1484 N of thrust in either direction.
This symmetric design is highly valued on battery cell and module assembly lines for non-rotating pushers and two-sided actuation. The through-rod uses a 20 mm diameter shaft on both ends, and the body length A(SCD) is 207 mm. The built-in magnet (-S) allows CMSG or DMSG sensors to clamp directly onto the barrel for precise end-of-stroke detection. Adjustable cushions, 21 mm long, decelerate the piston at stroke ends to reduce impact.
Airtac B06-SCD Battery-Specific Standard Cylinder B06-SCD50X250S Technical Specifications
| Model | Airtac B06-SCD Battery-Specific Standard Cylinder B06-SCD50X250S |
|---|---|
| Series | SCD double-rod tie-rod cylinder |
| Bore size | Ø50 mm |
| Rod diameter | Ø20 mm (both ends) |
| Stroke | 250 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-SCD50X250S Is Used
Cell Shuttle Transfer
Moves battery cells between processing stations using both rod ends to push and pull carriers symmetrically without rotation.
Module Stacking Pusher
Applies even 825 N clamping pressure on both sides of a battery module during stacking, ensuring precise alignment.
Tab Welding Positioner
Uses the built-in magnet and rear rod to carry a sensor flag, confirming exact positioning for automated tab welding.
Is the Airtac B06-SCD Battery-Specific Standard Cylinder B06-SCD50X250S the Right Cylinder?
Select this 50 mm bore when an application demands exactly 825 N of force in both directions at 0.5 MPa. If your battery handling system requires less force, stepping down to a 40 mm bore provides 528 N each way. If higher thrust is needed for heavy pack lifting, the 63 mm bore offers 1402 N. A single-rod SC cylinder is preferable if you only need one-sided actuation, while a true guided cylinder is recommended for heavy side loads, as the through rod improves guidance but cannot replace a dedicated linear guide.
For stroke lengths of 250 mm or more, the unsupported rod length increases the risk of bending under lateral loads. Use an external guide rail to support the tooling. To replace this unit, match the 50 mm bore, 250 mm stroke, PT1/4 port thread, basic mounting, and the -S magnet option exactly.
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-SCD50X250S FAQ
The B06- prefix indicates this is an AirTAC battery-manufacturing dedicated cylinder. It is mechanically identical to the standard SCD50X250S, featuring the same 50 mm bore, 250 mm stroke, and 825 N equal push/pull force, simply designated for battery industry applications.
The double-rod design provides identical 825 N force in both directions and allows tooling to be mounted on both ends. It offers better anti-rotation characteristics than a single-rod cylinder, making it ideal for battery line shuttles and two-sided pushers.
