Industrial Carbon Brushes: All Materials and Dimensions according to DIN 43000
Our industrial carbon brushes are classified according to standards DIN 43000 and IEC 136, offering a reliable solution for power transmission to commutators and slip rings. The dimensions of the carbon brushes are specified in the order t x a x r: tangential (width), axial (length), and radial (height).
Your Advantages – Precision and Material Variety
- Standardized Quality: Dimensions and cable diameters are standardized according to DIN 43000 and DIN 43002.
- Comprehensive Material Selection: Available as graphite carbon-GK, bakelite carbon-BK, noble carbon-EK, and bronze carbon-BKo.
- Specialized for Every Application: From hard carbons for small motors to noble carbons with excellent commutation properties.
- Flexible Connections: Cables can be provided with insulation (e.g., silicone tubing) as well as suitable cable lugs or connectors.

Material Overview and Application Specifications
When ordering, please specify the desired material type, dimensions (t x a x r), visible cable length, cable diameter, cable design, and cable lug/connector. The minimum order quantity is 6 pieces/type.
| Material | Properties & Area of Application |
|---|---|
| Hard Carbons | Strong binding (amorphous carbon materials), greater hardness. Used on commutators with non-undercut mica insulation (almost only in small motors now). |
| Graphite Carbons (GK) | Suitable for high peripheral speeds, low abrasive effect. Mica insulation should be undercut. |
| Bakelite Carbons (BK) | Resin-bonded with high contact voltage, high transverse resistance. For particularly difficult commutation at not too high current densities. |
| Noble Carbons (EK) | Electrographite material (transformed at 2,500° C). Significant improvement in electrical/thermal conductivity and burn-off resistance. Excellent commutation properties (mica insulation should be undercut). |
| Bronze Carbons (BKo) | Contain copper/other metals. Higher conductivity, lower contact resistance. Used on slip rings and in low-voltage machines. |
| Silver Carbons | Suitable for transmitting lowest voltages for measurement currents, tachogenerators, and contacts. |
