Hybrid Bearings for an Oil Pump in a Locomotive

(Austria)

Application:

  • Oil pump for transformer oil cooler in the Taurus locomotive

Problem:

  • Initial solution with standard bearings did not offer sufficient life time
  • NKE engineering established electrical corrosion as the root cause for failures

NKE Solution: 

  • Bearings with ceramic balls preventing the passage of electric current – 3306-B-TV-C3-SQ77B and 6305-C3-SQ77B
