New Energy Vehicles Shaft Grounding Ring Alloy Nickel Coated for Safe Protection Bearings Electric Drives Model V-562 Static
Description
Volsun’s New Energy Vehicles Shaft Grounding Ring Alloy Nickel Coated Model V-562 Static is a reliable, easy-to-install solution designed to protect bearings and electric drives in modern electric vehicles. Built to meet the demands of high-performance automotive environments, this grounding ring offers consistent, long-lasting protection against shaft currents and electrostatic discharge that can damage bearings and reduce component life.
Constructed from a durable alloy and finished with a nickel coating, the V-562 combines strength and corrosion resistance. The nickel plating provides a smooth, conductive surface that resists wear and oxidation, ensuring reliable contact with the shaft over extended service intervals. The alloy core gives the ring structural stability so it maintains shape and performance under vibration, heat, and mechanical stress typically found in electric drive systems.
The ring’s design prioritizes effective grounding while minimizing maintenance. It features a robust contact element that maintains stable electrical connection to the shaft, diverting harmful stray currents safely to ground. This reduces the risk of fluting, pitting, and premature failure of bearings, helping to extend the life of both bearings and associated electric drive components. The grounding path is engineered to handle typical shaft current magnitudes encountered in new energy vehicles, ensuring safe dissipation without impact to drive performance.
Installation is straightforward, saving time for service technicians and reducing downtime. The V-562 is sized and shaped to fit common shaft profiles used in electric motors and gearboxes. Its compact form factor allows integration within tight spaces while offering accessible connection points for grounding leads. Clear mounting features and a user-focused design make alignment and securing fast and reliable.
Durability and safety are central to Volsun’s design. The nickel-coated alloy resists environmental challenges such as moisture, dirt, and salt commonly found on roads, while the construction withstands repeated starts, stops, and torque fluctuations. These traits make V-562 suitable for passenger EVs, commercial electric vehicles, and other battery-powered mobility platforms that demand robust electrical protection.
Beyond protection, the grounding ring supports smoother operation. By preventing electrical damage to bearings, it helps maintain low friction, reduce noise, and preserve mechanical efficiency. This contributes to consistent drive performance, lower maintenance costs, and improved vehicle reliability over the life of the drivetrain.
Volsun’s Model V-562 Static Shaft Grounding Ring Alloy Nickel Coated is an effective, low-maintenance choice for safeguarding bearings and electric drives in new energy vehicles. Its durable construction, reliable conductivity, and easy installation make it an essential component for engineers and technicians focused on longevity and safety in electrified drivetrains
Product Overview
Volsun VS-RD Series Shaft Grounding Rings
Description
VS-RD series shaft grounding rings are composed of conductive fibers and metal bodies and are used for electric corrosion protection of variable frequency motors and their coupling equipment. VS-RD series conductive rings can reduce the potential induction between the bearing and the grounded chassis, effectively solve the phenomenon of electrical corrosion caused by shaft current, and protect the bearing from damage
