Types of Electrically Insulated Roller Bearings

Coated bearings are offered to avoid pitting. These are made with either ceramic or resin insulations and work in an array of applications. Applications such as wind turbines, variable speed motors in wastewater plants and traction railway car motors do well with the help of these bearings.

Applications where electric pitting is especially problematic would do well with hybrid bearings.

These improve the dissipation of heat and reduce the mass of rotation to keep electrical charges from passing through.

Ceramic hybrid bearings make use of conventional steel inner and outer rings. Silicon nitride rolling elements work with the bearings to keep them insulated properly.
