What are Electrically insulated rolling 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.
