VoltPath Shunt Bearing
To maintain the lifetime of bearings in e-mobility powertrains, preventive measures against parasitic bearing currents are essential, in particular for the newest generation of drive systems. The VoltPath Shunt bearing is an efficient countermeasure to prevent bearing damage caused by capacitive discharge currents (EDM). This bearing is characterized by the integration of a grounding element with high conductivity in the bearing.
Highlights
- Electrical robustness
- Cost-savings on system level due to assembly as 1-part unit
- Reliable and long-lasting
Advantages
- Prevention of bearing damages caused by EDM currents
- Downsizing in axial direction (up to 5 mm)
- Low frictional power losses
- No additional machining of housing/shaft
- Lower sensitivity to shaft bending & tilting
Features
- Integrated grounding ring with low impedance for better conductivity
- High speed capability with speed factor up to n x dm = 2.4 x 106 mm/min (example 6308 bearing: 37,000 rpm)
- Suitable for wet & dry environment
