Electrically Insulated Roller Bearings

Electrically insulated rolling bearings are bearings that have electrical insulation built into them. With this insulation, these bearings are able to provide superior protection against electrical corrosion or currents passing through them.

They can help keep a variety of applications moving smoothly with less need for repairs and routine greasing maintenance, too.

Electrical pitting can occur in bearings as a result of current leaks when they are used in electrical equipment like power generators or motors. What is more, the bearings can start to spark and can become so damaged that they fail. This can mean an entire system will come to a halt.

Electrical pitting can be avoided when electrically insulated ceramic bearings are used. There are a variety of bearings with insulation available on the market.

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.
