Technical Parameters

• Superior Contact Material: The gold-gold contacts offer exceptional electrical conductivity and thermal conductivity, coupled with a low temperature coefficient of resistance. These contacts exhibit remarkable resistance to sulfurization, oxidation, and corrosive gases, ensuring long - term stable performance. Additionally, their optimal hardness provides excellent resistance to welding, arc corrosion, and burns, significantly enhancing wear resistance and reliability.

• Precision Integrated Casting: Our advanced integrated casting process ensures unparalleled concentricity between the ring groove and the bearing, with a tolerance of ≤ 0.01mm. This meticulous craftsmanship minimizes rotational vibrations and ensures smooth, consistent operation even at high speeds.

• Mirror - Finish Processing: Employing state - of - the - art mirror processing technology, we achieve an ultra - smooth contact surface on the slip ring, with a surface roughness of Ra0.02. This precision finish guarantees a more reliable electrical connection, reducing signal loss and enhancing overall transmission quality.
• High - Precision Component Manufacturing: Our slip rings are crafted using a precision component manufacturing process, with dimensional tolerances controlled within < 0.01mm. This high - precision engineering results in stable contact performance, minimizing electrical fluctuations and ensuring consistent power and signal transmission.
• Innovative Brush Design: Our uniquely designed brushes feature a near - zero pressure mechanism, which not only reduces friction but also extends the operational lifespan of the slip ring by up to one - third. This breakthrough design ensures prolonged service life without sacrificing performance.
• Compact and Space - Efficient Design: Despite its advanced technical features, the slip ring maintains a small footprint and a compact structure. This design flexibility allows it to seamlessly integrate into applications with stringent space constraints, making it the ideal choice for space - limited environments.
