BLASI – Silberkohle-Rolle 20mm
The BLASI Silberkohle-Rolle 20mm serves as a precision silver-graphite roller contact essential for slip ring and current collection systems in automatic door operators. This 20mm diameter component provides low-resistance electrical connectivity with minimal wear characteristics, optimized for continuous rotation in commercial revolving door applications. The silver-graphite composition of Silberkohle-Rolle ensures reliable signal transmission and power delivery between stationary controls and rotating assemblies while maintaining stable contact pressure. Engineered for high-traffic environments, it delivers maintenance-free performance critical for uninterrupted safety sensor operation and synchronized door control.
Product Details
Specifically engineered for BLASI slip ring assemblies, the 20mm silver-graphite roller utilizes advanced composite material combining silver’s superior conductivity with graphite’s self-lubricating properties, achieving exceptionally low transition resistance essential for clean signal transmission from distributed safety sensors mounted on rotating door leaves. The precision 20mm diameter matches standard slip ring track specifications while the roller geometry distributes contact pressure evenly, preventing localized wear common in traditional carbon brushes.
The roller design of Silberkohle-Rolle excels in continuous low-speed rotation typical of pedestrian revolving doors, maintaining electrical continuity through millions of revolutions without requiring periodic replacement or maintenance intervention. Robust construction withstands environmental vibration, temperature fluctuations, and mechanical stresses characteristic of architectural entrance environments while preserving IP-rated sealing integrity essential for reliable long-term performance.
Technicians specify silver-graphite rollers for premium BLASI installations demanding guaranteed electrical contact reliability, confident in their proven ability to sustain critical safety circuit continuity supporting EN 16005 compliance across high-volume retail, hospitality, and institutional applications where seamless door operation directly impacts accessibility and user safety.
