Carbon Brushes for Slip Ring Applications

Sliding Contacts for Consistent Performance in Power and Signal Transmission

Stable electrical properties are essential in slip ring applications. Sliding contacts must operate reliably over the long term without disruptions or contact loss – while requiring as little maintenance as possible. Low electrical noise is crucial, especially for sensitive measurement or control signals.

Depending on system requirements, carbon brushes with precisely tuned running properties are used. The goal is maximum operational safety with minimal material wear – even under temperature fluctuations, humidity, or vibration.

Requirements for carbon brushes in slip ring systems:

Low electrical noise
Uniform wear over long service life
High contact reliability under varying loads
Low heat generation even under high current loads

Materials & Technologies

Suitable Materials and Designs for Every Application Profile

Slip ring carbon brushes must be precisely adapted to the operating conditions – whether for sensitive signals or high current loads. Materials such as electrographite, metal graphite, or specially developed carbon blends offer different advantages in conductivity, temperature resistance, and wear behavior.

Geometry and impregnations are individually designed by Schunk – for maximum efficiency and service life, even under aggressive environmental conditions.

Carbon Brushes for Critical Applications & Sensitive Signal Technology

In various systems such as scanners, crane systems, or steel plants, carbon brushes must perform reliably when it matters. Schunk develops solutions for environments with vibration, moisture, temperature fluctuations, or aggressive media.

Industries with elevated demands:

Medical technology: Low-noise transmission even in compact designs – ideal for CT scanners with highest demands on image quality and diagnostic accuracy.
Defense technology: Stable data and power transmission despite mechanical vibration, climate fluctuations, and electromagnetic interference.
Steel industry: Reliable operation under a wide range of environmental and load conditions
Port, crane & offshore applications: Corrosion-resistant carbons for salty air and changing weather conditions
