Break Free From Rotational Limits: Slip Rings Ensure Uninterrupted Power/data Transmission During 360° Operation.

Technical parameters

1. Core Friction Pair Technology of SPR-ing: The gold-gold contact technology lies at the heart of SPR-ing, representing a pinnacle of engineering excellence. This cutting-edge contact technology minimizes electrical resistance and wear, significantly enhancing the durability and reliability of the slip ring. By reducing the likelihood of oxidation and corrosion, it ensures a substantially extended service life, allowing the slip ring to perform consistently over an extended period. This is particularly crucial in applications where continuous and reliable operation is indispensable, such as in high-precision industrial machinery and critical aerospace systems.

2. Integrated Pouring Process: Our state-of-the-art integrated pouring process is a testament to our commitment to precision engineering. It guarantees that the concentricity between the ring groove and the bearing is maintained at an astoundingly low tolerance level of ≤0.01mm. This meticulous control over concentricity is essential for minimizing vibration and ensuring smooth, stable operation of the slip ring. Even under high-speed rotation and heavy loads, the low concentricity deviation ensures that the electrical and mechanical components function harmoniously, preventing premature wear and enhancing overall system performance.

3. Mirror Processing Technology: Employing advanced mirror processing technology, we achieve an unparalleled surface finish on the slip ring's contact surface. The finish can reach a microscopic smoothness level of Ra0.02, which translates to an ultra-smooth surface that maximizes the contact area between the contacts. This increased contact area, combined with the smooth surface, significantly reduces electrical contact resistance, enabling more efficient signal and power transmission. As a result, the slip ring provides a highly reliable connection, minimizing the risk of signal loss or electrical interference, even in the most demanding operating conditions.

4. Precision Parts Manufacturing Process: Our manufacturing process for precision parts adheres to the strictest quality standards, with dimensional tolerances kept well below 0.01mm. This high level of precision ensures that each component of the slip ring is manufactured to exact specifications, guaranteeing consistent performance and reliability. The tight dimensional control not only enhances the mechanical integrity of the slip ring but also contributes to its electrical stability, allowing it to operate with exceptional precision and consistency across a wide range of applications.

5. Advanced Brush Filament Modulation Process: Our innovative brush filament modulation process features a near-zero pressure brush design and meticulous debugging process. This breakthrough technology optimizes the interaction between the brushes and the slip ring surface, reducing friction and wear. As a result, the lifespan of the slip ring is extended by an impressive one-third compared to conventional designs. This extended life not only reduces maintenance costs but also minimizes downtime, making our slip rings an ideal choice for applications where continuous operation is critical.

6. Compact Design: Despite its advanced functionality and high-performance capabilities, our slip ring boasts a small size and compact structure. This design feature allows it to fit seamlessly into space-constrained environments, providing a versatile solution for a wide range of applications. Whether it's in compact industrial equipment, robotics, or portable electronic devices, our slip ring can be easily integrated without sacrificing performance or functionality.

7. Robust Stainless Steel Structure: Constructed with an integral 304 stainless steel metal structure, our slip ring offers exceptional sealing and durability. The stainless steel construction provides excellent resistance to corrosion, abrasion, and harsh environmental conditions, making it suitable for use in extremely demanding environments. Whether it's exposed to high humidity, dust, chemicals, or extreme temperatures, the slip ring's robust structure ensures reliable operation, protecting the internal components and maintaining its performance integrity over time.

8. High-Speed Capability: Our slip ring is engineered to deliver outstanding performance at high speeds, with a maximum rotational speed of 18,000 revolutions per minute (rpm). This high-speed capability makes it ideal for applications that require rapid rotation, such as high-speed centrifuges, wind turbines, and aerospace equipment. Despite the high rotational speed, the slip ring maintains stable electrical transmission and mechanical operation, ensuring reliable performance even under extreme conditions.

9. Long-Lasting Operation: At its maximum speed of 18,000 rpm, our slip ring can operate continuously for an impressive 96 hours. This remarkable endurance showcases the slip ring's superior design and construction quality, as well as its ability to withstand prolonged high-speed operation without degradation in performance. This long-lasting operation makes our slip ring a reliable choice for applications that require continuous, uninterrupted operation, reducing the need for frequent maintenance and replacement.

Applications: Used for high-speed test platform strain gauge signals, thermocouple signals, etc., such as aero engine testing, high-speed rail component testing, automotive wheel hub performance testing!
