Carbon Brushes for Slip Ring Applications – Precise Contact Solutions for Sensitive Systems

Schunk delivers customized solutions that meet the highest demands in contact quality, smooth operation, and service life – even in demanding industrial environments with strong electrical, mechanical, and climatic stresses. Beyond mere current transmission, signal accuracy is critical: whether analog measurements, digital control signals, or combined power and data transmission – our solutions ensure interference-free operation, even with complex signal architectures.

Materials, Brush Designs & Adaptation to Usage Profile

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

Geometry, impregnation, and dust channels are also individually designed by Schunk – for maximum efficiency and long service life. Dust-repellent structures, corrosion-resistant impregnations, and temperature-stable formulations ensure lasting stability – even under harsh industrial conditions.

Carbon Brushes for Critical Applications & Sensitive Signal Technology

In sensitive systems like scanners, cranes, or steel plants, carbon brushes must not only conduct – they must function reliably when it matters. Schunk develops solutions for environments involving vibration, humidity, temperature changes, or aggressive media.
