Product Description
VS-RD series shaft grounding rings are composed of conductive fibers and metal bodies and are used for electric corrosion protection of variable frequency motors and their coupling equipment. VS-RD series conductive rings can reduce the potential induction between the bearing and the grounded chassis, effectively solve the phenomenon of electrical corrosion caused by shaft current, and protect the bearing from damage.
