Bearing and return line flush

Steel Manufacturing plant close up

This critical service can help minimize operational costs by removing potentially harmful deposits that can cause lubricant leaks, bearing failure and unscheduled maintenance downtime.


After a thorough bearing inspection, expert engineers will, if necessary, recommend and oversee a hot-oil bearing and return line flush to remove deposits caused by contamination, wear and other factors.


Expert engineers will work with you to:

  • Identify service objectives that help ensure optimal equipment performance
  • Assist in establishing site-specific requirements for lubricant performance and quality assurance
  • Coordinate arrangements with the service technician who will:
    • Complete the flushing process
    • Gather key baseline and other relevant data

Deliverable: An Engineering Service Report details the completed process, documents system cleanliness before and after treatment, recommends steps to maintain cleanliness and provides an estimated value of the service. Distribute and present the completed report to plant management and key personnel.

Common opportunity areas

  • Improper lubricant flow rates
  • Bearing failures attributed to lack of lubrication
  • Lubricant leakage
  • Lubricant contamination

Safety, health and environment

Field engineers are attuned to the hazards of handling, storing and using petroleum products. They strictly observe safety and environmental rules and ExxonMobil and customer safety practices. They coordinate efforts through designated plant personnel verifying electrical and mechanical lockout and proper tagging prior to working on equipment, and providing recommendations to help reduce hazards.
