Electrical currents passing through bearings can lead to significant damage. Over time, this exposure creates visible signs like pits and grooves on the surface, altering its smoothness. As a result, the equipment generates more noise and vibration, eventually failing completely. These issues can be costly, often causing unexpected downtime and requiring expensive repairs or replacements. While not every bearing experiences damage from electrical currents and not every circuit causes harm, certain scenarios commonly lead to this problem. Improper grounding is one situation where the current often seeks the path of least resistance, frequently flowing through exposed bearings. In setups involving AC/DC motors with variable frequency drives (VFDs), the issue is similar—voltage accumulates on the motor shaft and discharges into the bearings. This discharge forms fluting or pitting patterns inside the bearing, leading to equipment malfunctions. To address this challenge, replacing conventional bearings with ceramic hybrid bearings can be an effective solution. These bearings provide superior electrical and thermal insulation, preventing current discharge and making them ideal for applications with VFDs or other grounded motors. ### What Are Ceramic Hybrid Ball Bearings? Ceramic hybrid bearings combine ceramic rolling elements with steel inner and outer races. Their design and composition make them highly resistant to electrical damage. Ceramic bearings offer excellent insulation, eliminating electric arcing and fluting. Additionally, they come with double shielding and non-conductive properties, ensuring stable performance even under extreme conditions. For instance, Nachi ceramic hybrid ball bearings stand out as some of the most durable alternatives to traditional steel bearings. They are dimensionally compatible with most existing bearings, simplifying the installation process and reducing costs associated with modifications. ### Additional Advantages of Ceramic Hybrid Ball Bearings Beyond their insulating qualities, ceramic hybrid bearings offer numerous other benefits: - **Lightweight Construction**: Reduces wear and tear. - **Safe Operation in Harsh Conditions**: Ensures reliability in extreme environments. - **Wider Speed Range**: Offers flexibility for various applications. - **Low Friction Coefficient**: Enables faster rotations and improved power output. - **Extended Lifespan**: Lower risk of premature failure, providing long-term cost savings. - **Reduced Lubrication Needs**: Eliminates reliance on heavy oils or greases, minimizing contamination risks and environmental impact. These advantages make ceramic hybrid bearings an excellent choice for industries requiring enhanced bearing protection, such as food processing, HVAC units, compressors, fans, generators, and data centers. ### Protect Your Bearings With Emerson Bearing Bearings face threats from electrical currents as well as various operational and environmental factors.
