Main Bearing Flushing

Extend wind turbine main bearing life to reduce O&M costs

Romax InSight’s patented main bearing grease flushing technology reduces the metallic particulates and water content that occur in wind turbines by more than 95% and significantly extends their life.

Romax provides main bearing grease flushing, onshore and offshore as a turnkey service or in conjunction with local site teams. Our specialised equipment allows for almost all of the old grease to be removed up-tower and replaced with fresh grease.

Key Benefits:

  • Extend life to reduce unplanned maintenance costs
  • Reduce and manage the cost of main bearing failures
  • Minimise unscheduled down time
  • Optimise repair schedules

Talk to us about two strategies for implementing improved maintenance for main bearings at your wind farms:

Strategy #1: During early stages of wear

  • Flush proactively using predictive maintenance for long life extension.

Strategy #2: During late stages of wear

  • Flush bearings found in poor condition to extend life as part of the process of managing the cost of failures.


Take a data-driven approach to wind power O&M. Combine our flushing service with our predictive maintenance technology and we can help you select the bearings most in need of life extension. 

We offer the following services: 

  • ecoCMS™ proven low-cost condition monitoring system to enable main bearing monitoring where CMS is not installed or not affordable. 
  • Field Pro™ service & inspection app and web portal to record and track main bearing condition for the life of your assets.

What our customers say

Kruger Energy
Romax InSight has performed their flushing process on several of our main bearings, which has helped extend their life and maintain productivity. We are now implementing flushing as part of our main bearing maintenance practices and this will contribute to reducing our overall maintenance costs.

JJ Davis, Operations & Maintenance Manager, Kruger Energy

We saved significant money on this bearing failure due to the Romax process by optimizing repair scheduling and reducing downtime. We would look to this process on future failing bearings to save money again.
