๐ง Spot the Failure Mode | Engineering Diagnostic
Maintenance & Reliability Leads: Take a close look at this spherical roller bearing pulled during a planned overhaul. ๐
The drive was running hot (>95^โC) with audible rumble under heavy radial load. When stripped on the bench, our team found heavy outer ring raceway scoring, discoloured grease grease-purge, and bore clearance anomalies.
What is the primary root cause behind this premature failure?
๐ A) Thermal Runaway from Over-Greasing (Churning & high internal pressure)
๐ B) Incorrect Shaft Fit / Inadequate Radial Internal Clearance (RIC)
๐ C) Severe Angular Misalignment (Skewed roller tracking)
๐ D) Static Brinelling from Shock Loading

(Weโll pin the full root cause analysis and clearance inspection tolerances tomorrow morning).
