    Prevent motor downtime by protecting bearings from stray currents generated by variable frequency drives. These grounding rings create a path for stray currents, so they won't damage bearing surfaces. Use them on AC motors.
    One Piece—One-piece rings slide on from the end of the shaft.
    Two Piece—Two-piece rings simplify installation when motors are connected to equipment.
