Dirt : One of the Challenges of Fleet Owners Encounter with Reduced Shell Bearing Lifespans

Bearings are mechanical components that support the smooth movement of rotating parts by reducing friction between them.

However, they are susceptible to failure, and a significant portion, around 45.4%, of bearing failures are caused by dirt contamination.

Let's see, the three main factors that cause dirt in bearings.

Improper/poor operational practices, delays, and neglecting maintenance tasks, such as not changing the filter or overlooking maintenance, can lead to the accumulation of dirt in bearings.

1. Operations-Related Issues

Traditional oil analysis is a time-consuming process that involves taking oil samples, sending them to a lab for testing, and waiting for the results. This delay can hinder the timely identification of dirt-related problems, potentially leading to bearing damage.

2. Lab Oil Analysis

Studies reveal that even new oil stored in barrels has contaminations up to NAS 10 or 11 whereas required engine oil NAS should be in the range of NAS 8 to 9 (© Parker Guide to Contamination Standards)

3. Retaining oil quality

Understanding the main factors causing dirt in bearings is vital for improving equipment reliability, efficiency, and longevity.

Implementing Neptunus' kidney loop filtration technology effectively removes dirt and particles up to 3 Microns, further enhancing bearing performance and lifespan.
