Airtac B04-SCD Specialized Standard Cylinder for Construction Machinery B04-SCD100X100S
The AirTAC Airtac B04-SCD Specialized Standard Cylinder for Construction Machinery B04-SCD100X100S is a genuine double-acting DOUBLE-ROD air cylinder: the Ø25mm piston rod extends from BOTH end caps, giving equal effective area — and therefore equal force — in push and pull. Ø100mm bore, 100mm stroke, PT1/2 ports and adjustable end cushioning.

About the Airtac B04-SCD Specialized Standard Cylinder for Construction Machinery B04-SCD100X100S
The B04-SCD100X100S is AirTAC's construction-machinery dedicated variant of the SCD100X100S double-rod cylinder, carrying identical mechanical specifications. The B04- prefix simply flags it as heavy-equipment builder stock. Featuring a 100mm bore and 100mm stroke, this double-acting tie-rod cylinder produces 3681 N of thrust in both directions at 0.5 MPa, climbing to 6626 N at 0.9 MPa.
Because the Ø25mm piston rod passes through both end caps, the effective pressure area is equal on both sides. This yields identical push and pull forces, symmetric bearing wear, and superior anti-rotation resistance compared to a single-rod unit. The code includes an S suffix, meaning a built-in magnet is installed for CMSG/DMSG/EMSG sensor tracking. It uses PT1/2 ports and adjustable cushions measuring 29mm.
Airtac B04-SCD Specialized Standard Cylinder for Construction Machinery B04-SCD100X100S Technical Specifications
| Model | Airtac B04-SCD Specialized Standard Cylinder for Construction Machinery B04-SCD100X100S |
|---|---|
| Series | SCD double-rod tie-rod cylinder |
| Bore size | Ø100 mm |
| Rod diameter | Ø25 mm (both ends) |
| Stroke | 100 mm |
| Rod configuration | Double rod — rod through both caps |
| Acting type | Double acting |
| Port size | PT1/2 |
| Rod thread | M20×1.5 |
| 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, 29 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 (Ø100mm, double rod)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3682 N | 3682 N |
| 0.7 MPa | 5154 N | 5154 N |
| Max (@1.0 MPa) | 751 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 B04-SCD Specialized Standard Cylinder for Construction Machinery B04-SCD100X100S Is Used
Heavy Equipment Actuation
Drives symmetric pushing and pulling mechanisms on construction machinery where the B04 prefix indicates dedicated heavy-equipment integration.
Dual-Sided Tooling Transfer
Uses the through-rod to carry tooling on both ends, allowing a single cylinder to alternately actuate two separate workstations with 3681 N of force.
Anti-Rotation Pusher
The dual-rod design resists torsional twisting better than a single rod, ensuring a straight push on heavy material handling panels.
Is the Airtac B04-SCD Specialized Standard Cylinder for Construction Machinery B04-SCD100X100S the Right Cylinder?
Select this 100mm bore when an application requires substantial equal bi-directional force (3681 N at 0.5 MPa) and a rear rod for mounting secondary tooling or a stopper flag. If your machine only needs force in one direction, the standard single-rod AirTAC SC100X100 is lighter and more compact. If the mechanism experiences heavy lateral loads, a dedicated guided cylinder is recommended over relying solely on the through-rod for support.
When replacing this unit, match the 100mm bore, 100mm stroke, PT1/2 port thread, basic mounting style, and the built-in magnet (-S). Note that air pressure does not lock the piston; if the heavy-equipment load must remain fixed during air loss, a mechanical lock or external rod brake is mandatory.
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 B04-SCD Specialized Standard Cylinder for Construction Machinery B04-SCD100X100S FAQ
The B04- prefix designates this as an AirTAC construction-machinery dedicated cylinder. It is mechanically identical to the standard SCD100X100S, with the same 100mm bore, 100mm stroke, and 3681 N equal push/pull force at 0.5 MPa.
The double-rod design provides identical push and pull forces (3681 N at 0.5 MPa) because the rod area is subtracted from both chambers. It also offers a rear rod for mounting sensors or tooling, and improves anti-rotation resistance over the single-rod version.
