VL0241 insulated deep groove ball bearings feature an aluminum oxide ceramic coating on the outer ring, providing electrical insulation resistance above 100 MΩ at 1000 VDC. Designed to prevent electrical erosion caused by shaft currents in variable frequency drive (VFD) motors, these bearings are essential for traction motors in locomotives, wind turbine generators, and large industrial motors where stray currents can significantly reduce bearing life.
