Application:
- Traction motor for railway vehicles
Problem:
- Frequent bearing failures on the non-locating side due to overheating
Assignment:
- Technical root cause analysis
- Improving bearing performance
- Increasing operational safety
NKE Solution:
- Elimination of glass fibre insulation → better heat dissipation
- Re-Definition of sideplay of the labyrinth sealing system
- Raising radial clearance to C4H
- Introduction of electrically insulated bearings
- No change of adjacent parts required due to customized bearing dimensions
Results:
- No bearing failures since conversion to NKE special bearings
