Airtac B06-SCD Battery-Specific Standard Cylinder B06-SCD40X25S
The AirTAC Airtac B06-SCD Battery-Specific Standard Cylinder B06-SCD40X25S is a genuine double-acting DOUBLE-ROD air cylinder: the Ø16mm piston rod extends from BOTH end caps, giving equal effective area — and therefore equal force — in push and pull. Ø40mm bore, 25mm stroke, PT1/4 ports and adjustable end cushioning.

About the Airtac B06-SCD Battery-Specific Standard Cylinder B06-SCD40X25S
The B06-SCD40X25S 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 SCD40X25S. Because the piston rod passes through both end caps, the effective area is equal in both chambers, yielding 528 N of thrust and retraction force at 0.5 MPa. This symmetric output is ideal for compact cell stacking and tabbing operations in battery module assembly.
Featuring a 40 mm bore and a short 25 mm stroke, this unit includes a built-in magnet (the S suffix) allowing CMSG or DMSG sensors to track position along the 191 mm body length A(SCD). It uses a Ø16 rod on both ends, PT1/4 ports, and adjustable cushions measuring 21 mm to soften end-of-stroke impacts.
Airtac B06-SCD Battery-Specific Standard Cylinder B06-SCD40X25S Technical Specifications
| Model | Airtac B06-SCD Battery-Specific Standard Cylinder B06-SCD40X25S |
|---|---|
| Series | SCD double-rod tie-rod cylinder |
| Bore size | Ø40 mm |
| Rod diameter | Ø16 mm (both ends) |
| Stroke | 25 mm |
| Rod configuration | Double rod — rod through both caps |
| Acting type | Double acting |
| Port size | PT1/4 |
| Rod thread | M12×1.25 |
| 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 (Ø40mm, double rod)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 528 N | 528 N |
| 0.7 MPa | 739 N | 739 N |
| Max (@1.0 MPa) | 108 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-SCD40X25S Is Used
Cell Stacking Press
Provides equal 528 N push and pull force to compress and align prismatic battery cells during module stacking, ensuring consistent stack pressure.
Tabbing Shuttle
The through-rod design carries a secondary tooling flag on the rear side, allowing synchronized front and rear actuation for battery tab welding shuttles.
Anti-Rotation Handling
Dual rods offer better resistance to twist compared to single-rod types, keeping battery handling grippers stable during short 25 mm transfer movements.
Is the Airtac B06-SCD Battery-Specific Standard Cylinder B06-SCD40X25S the Right Cylinder?
Select this 40 mm bore when a battery-handling fixture requires identical force in both directions within a tight 25 mm stroke envelope. If your application needs less force, stepping down to a 32 mm bore provides 345 N at 0.5 MPa; conversely, a 50 mm bore offers 825 N for heavier pack manipulation. A single-rod SC cylinder is preferable if rear tooling or symmetric bearing loading is unnecessary, while a true guided cylinder should be chosen for high side-load scenarios.
When replacing this unit, ensure the five critical parameters match: 40 mm bore, 25 mm stroke, PT1/4 port thread, basic SCD mounting, and the built-in magnet. Remember that the adjustable air cushion only decelerates the piston near stroke end; it does not lock or hold the load. If battery cell positioning must be maintained 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-SCD40X25S FAQ
The B06- prefix indicates this is an AirTAC cylinder dedicated to battery-manufacturing lines. It is mechanically identical to the standard SCD40X25S, offering the same 40 mm bore, 25 mm stroke, and 528 N equal push/pull force at 0.5 MPa.
A double-rod SCD cylinder provides identical thrust and retraction forces because the rod area is subtracted from both sides. This allows symmetric loading of the bearings and provides a rear rod for mounting secondary tooling or sensor flags, which is often required in cell handling and tabbing processes.
