High-Speed Rail Traction Motor Bearing Oil
VOP-N-30 polishing at every depot eliminated bearing pitting on high-speed rail traction motors.
Challenge
Bearing pitting on traction motors after 600,000 km. Oil analysis showed wear particles above ISO 4406 21/19/16.
Solution
Compact skid-mounted VOP-N-30 purifier at each maintenance depot. Polishing cycle: every 50,000 km.
Outcome
Bearing pitting incidents eliminated. ISO 4406 cleanliness maintained at 17/15/11. Fleet availability metric rose 8%.
