Airtac B06-SCD Battery-Specific Standard Cylinder B06-SCD40X250S
The AirTAC Airtac B06-SCD Battery-Specific Standard Cylinder B06-SCD40X250S 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, 250mm stroke, PT1/4 ports and adjustable end cushioning.

About the Airtac B06-SCD Battery-Specific Standard Cylinder B06-SCD40X250S
The B06-SCD40X250S is an AirTAC double-acting, double-rod cylinder engineered for battery manufacturing environments. The B06- prefix designates this as a battery-manufacturing dedicated variant of the standard SCD40X250S, meaning it is mechanically identical to the base model. The through-rod design yields identical thrust in both directions, providing 528 N of force at 0.5 MPa and 950 N at 0.9 MPa.
Because the Ø16 mm piston rod passes through both end caps, you get equal push and pull forces along with superior anti-rotation characteristics. This 250 mm stroke unit includes a built-in magnet for CMSG/DMSG/EMSG sensor tracking, uses a PT1/4 port, and features adjustable cushions with a 21 mm stroke length to protect end-of-travel components.
Airtac B06-SCD Battery-Specific Standard Cylinder B06-SCD40X250S Technical Specifications
| Model | Airtac B06-SCD Battery-Specific Standard Cylinder B06-SCD40X250S |
|---|---|
| Series | SCD double-rod tie-rod cylinder |
| Bore size | Ø40 mm |
| Rod diameter | Ø16 mm (both ends) |
| Stroke | 250 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-SCD40X250S Is Used
Cell Shuttle Transfer
Moves battery cells between processing stations with equal push and pull force, ensuring stable two-sided actuation during high-speed transfer.
Module Stacking Pusher
Utilizes the anti-rotation properties of the double rod to push battery modules squarely into stacking fixtures without skewing.
Tab Welding Clamp
Applies symmetrical clamping pressure for battery tab welding, using the rear rod extension to mount a secondary tooling stop or sensor flag.
Is the Airtac B06-SCD Battery-Specific Standard Cylinder B06-SCD40X250S the Right Cylinder?
Choose this 40 mm bore when your battery assembly line needs 528 N of thrust in both directions without the full bulk of a 50 mm cylinder (which provides 825 N). If your application only requires force in one direction, a single-rod AirTAC SC cylinder is lighter and more compact. For high side-load situations on a 250 mm stroke, a dedicated guided cylinder is recommended over relying solely on the through-rod bearing support.
To replace this unit, match the 40 mm bore, 250 mm stroke, PT1/4 port thread, basic mounting style, and the built-in magnet (-S suffix). The SCD series uses a tie-rod construction and is not dimensionally interchangeable with ISO 15552 cylinders. Note that air pressure must be maintained to hold a load; the adjustable cushion decelerates the piston but does not function as a mechanical lock.
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-SCD40X250S FAQ
The B06- prefix indicates this is a battery-manufacturing dedicated cylinder. It is mechanically identical to the standard AirTAC SCD40X250S, offering the same 40 mm bore, 250 mm stroke, and 528 N equal push/pull force at 0.5 MPa.
A double-rod cylinder provides identical force in both directions because the rod area is subtracted from both chambers. It also offers better resistance to rod rotation and allows tooling or sensors to be mounted on the rear rod extension, which is ideal for precision battery assembly tasks.
