Product Overview
The SP013052 series products are exquisitely engineered to meet the stringent demands for small - space slip rings in rotary systems. With a compact size of merely Φ30mm×52mm and a lightweight design of 80g, these slip rings effortlessly fit into tight spaces where conventional models falter, offering unparalleled space - efficiency. They are rigorously tested and proven to perform flawlessly across the entire lifecycle of the system, from launch to long - term storage and continuous operation. During launch, the rugged construction and precision - balanced design of the SP013052 series enable it to withstand extreme mechanical stresses like high - g forces and intense vibrations. It maintains stable electrical transmission with a signal loss rate of less than 0.1% and a power drop - off within 0.5 volts, ensuring seamless system activation. For long - term storage, a proprietary multi - layer protective manufacturing process is employed. A specialized anti - corrosion compound coats the slip rings, creating an air - tight barrier against oxidation and moisture. Internally, components are treated with a low - volatility lubricant, preserving their functionality over time. As a result, the contact resistance increases negligibly by only 0.05 ohms after 12 months of storage. In operation, the slip rings can reach up to 10,000 RPM while maintaining an excellent electrical insulation of 500 megohms. Ideal for aerospace, robotics, and other high - tech fields, the SP013052 series offers a reliable, long - lasting solution for power and signal transmission.
Application areas: Used for high-speed testing platform strain gauge signals, thermocouple signals, etc., such as aircraft engine testing, high-speed rail component testing, automotive wheel hub performance testing!
Technical Advantages of Small High-Speed Slip Ring
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.
