The increase in the volume of variable frequency drive (VFD) electric motors and other machines where electrical currents are present has demanded the need for insulated bearings. Electrical currents can flow through the bearing, causing electrical arcing damage to the rolling contact surfaces and ultimately bearing failure. Ceramic coated bearings can prevent electrical pitting and fluting.
COATED BEARINGS
NTN's MEGAOHM Series of insulated bearings has been specifically designed to prevent electrical arcing in various applications. Coating the bearing's outer ring provides an insulating barrier against any stray currents that would pass through it.
MEGAOHM SERIES ADVANTAGES
- Ceramic coated for electrical insulation that prevents electrical pitting and fluting
- Drop-in replacement for standard bearings
- Cost-effective solution to combat stray electric currents
TRUSTED BY OEMS
MEGAOHM Series insulated bearings are designed to resist electric current damage. They offer protection to costly equipment, which is why OEMs use them for wind turbine generators, traction motors, paper, and textile rolls, VFD, and other electric motors used across many industrial applications.
