MEGAOHM is the ideal solution for protecting motors exposed to stray electrical currents. Its high-performance ceramic coating on outer ring against electrical currents up to 3,000 VDC, extends equipment service life, and reduces maintenance costs. Thanks to its standardized dimensions, the bearing is fully interchangeable with standard bearings.

The single row deep-groove ball bearing is the most popular bearing. It is available in a wide range of sizes with several possible options: sealing with shields or seals, presence of a retaining ring, varied clearances, several cage types, etc.
