Your engine’s crankshaft is one of the most expensive single components in your power plant. Yet, its survival entirely depends on layers of soft, sacrificial babbitt material sitting inside your main and connecting rod bearings.
These bearings do not actually touch the rotating steel journals during operation; instead, they rely on a high-pressure hydrodynamic oil wedge. Protecting that oil film is the single most important task for your plant’s lubrication management team.
Preventing Journal Scoring and Oil Film Breakdown
When main or rod bearings fail, the results are catastrophic—often resulting in a twisted crankshaft, ruined block tunnels, and months of costly downtime. Common precursors to bearing failure include:
- Fuel or Coolant Contamination in Oil: Dilutes oil viscosity and destroys load-bearing capacity.
- Cold Starts Under Load: Forcing high torque before oil pressure fully stabilizes across all galleries.
- Particulate Contamination: Inadequate filtration allowing grit to embed into the soft bearing material, turning the bearing surface into fine sandpaper against your crankshaft journals.
