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 and offer a reliable solution for current transfer 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 Diversity
- 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, electrographitic carbon-EK, and bronze carbon-BKo.
- Specialized for Every Application: From hard carbon for small motors to electrographitic carbon with excellent commutation properties.
- Flexible Connections: Cables can be equipped 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 & Application Area |
|---|---|
| Hard Carbons | Strong bonding (amorphous carbon materials), greater hardness. Used on commutators with non-undercut mica insulation (almost exclusively 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. |
| Electrographitic Carbons (EK) | Electrographite material (converted at 2,500° C). Significant improvement in electrical/thermal conductivity and resistance to wear. 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 very low voltages for measuring currents, tachogenerators, and contacts. |
