With 20 years of deep experience in polymer material research and development, Volsun has launched the VS-RD series shaft grounding ring, which is designed to solve various motor bearing electric corrosion problems. With its excellent conductivity and ultra-long service life, this series of products has quickly become the preferred solution for motor protection in the fields of new energy vehicles, industrial machinery, agricultural machinery, mining motors, wind power motors and household appliances.


 
 
So, what are the outstanding features of Volsun shaft grounding rings?
 
First of all, the core components of Volsun shaft grounding rings adopt a fully shielded structure and are combined with an independent patented electromagnetic compatibility design. This allows its signal transmission error to be controlled within an astonishing 0.01%, while the anti-electromagnetic interference capability is improved by 40%.
 
Secondly, this series of products uses high-performance carbon fiber materials with special surface treatment, which gives it an extremely long service life. After 100,000 fatigue tests, the carbon fiber material showed no wear at all. What is even more amazing is that in a wide temperature environment of -55℃ to +150℃, its conductive resistance fluctuation is always kept within 0.1Ω, far exceeding the industry average. What's more, by optimizing the ring structure design, the Volsun shaft grounding ring completely eliminates the spark discharge problem caused by poor contact of traditional conductive rings. It has been measured to run continuously for 300,000 kilometers without failure, and its life is twice that of ordinary products.
 
In addition, the Volsun shaft grounding ring also uses a unique self-lubricating coating technology, eliminating the trouble of applying lubricants regularly and greatly reducing maintenance costs. Its IP68-level waterproof and dustproof design enables it to operate stably in harsh environments with humidity up to 95% and dust concentration exceeding 100mg/m³, perfectly adapting to outdoor scenes such as wind power and port machinery.
 
The excellent performance of Volsun shaft grounding ring has been fully verified by a series of rigorous actual test data:
 
Service life test: In the State Grid UHV equipment, the VS-RD series conductive ring has been running continuously for 36 months, with a cumulative power transmission of more than 50 million degrees, and the conductive performance has remained consistent, and the failure rate has been reduced by 80% compared with similar products.

Environmental adaptability test: After being subjected to extreme tests such as continuous baking at 250℃ for 4 hours and cold start at -40℃ for 1000 times, the conductive ring remains intact, without deformation or oxidation, and all indicators are stable and reliable.

Vibration resistance test: After running for 1000 hours on the high-speed rail bogie simulation vibration platform (amplitude ±5mm, frequency 50Hz), the number of signal transmission interruptions is 0, which is far better than the industry standard requirement of ≤3 times.

Volsun VS-RD series shaft grounding rings provide a solid guarantee for the stable operation of various motors with their excellent performance and reliable quality. They are your ideal choice for solving the problem of electrical corrosion of motor bearings.
