The Importance of Insulated bearings
Insulated bearings, as key components in modern industrial equipment, are widely used in applications such as electric motors, wind power, and rail transportation. Their core advantage lies in effectively preventing electrical erosion. By applying a protective insulating coating on either the inner or outer ring, these bearings gain insulation properties that block stray currents from passing through. This not only protects the bearing from harsh operating conditions but also enhances equipment reliability and extends service life.
