Both Insulation and Conductivity features are necessary to mitigate eAxle current leakage. SKF Conductive Brush Ring, in combination with superior SKF Hybrid Bearing technology, provides a unique modular and scalable solution to eAxle parasitic current in EV applications, optimized versus system application with SKF Digital Development Methodology.
Its narrow profile and scalable design makes the SKF Conductive brush ring easy to integrate into new or existing powertrains. In a typical application, it will be installed at one end of the motor to provide grounding, while a SKF Hybrid Bearing provides an insulated connection at the other side.
High voltage platform is now under development in almost all customers to reduce the recharging time. The bearing premature failure caused by electric erosion is getting more frequent. SKF Hybrid ceramic bearing can solve the failure caused by electric erosion.
The SKF Conductive brush ring provides a reliable electrical connection between an EV eAxle rotor shaft and its housing, which increases eAxle lifetime expectations. When used in combination with SKF Hybrid ceramic ball bearings, it helps to even further alleviate parasitic current effects that can lead to premature failure in bearings and other components.
