Stories to Inspire

The Misaligned Bearing

A technician working on a high-speed turbine overlooked the bearing alignment during installation. As the turbine operated, the misaligned bearing caused excessive vibration and heat buildup. This negligence led to a catastrophic failure, damaging the turbine beyond repair.

Lesson Learned: Precision in bearing installation is crucial to ensure optimal performance and prevent costly consequences.

The Overlooked Lubrication

In a manufacturing plant, a conveyor system experienced frequent bearing failures. Investigation revealed that the bearings were not being lubricated as per the recommended schedule. The lack of lubrication led to premature wear and early bearing failure, disrupting production and increasing maintenance costs.

Lesson Learned: Regular lubrication is essential to extend bearing life and prevent unnecessary repairs.

The Stubborn Inspection

A power plant technician ignored multiple warning signs indicating a faulty angular contact bearing in a critical generator. The technician assumed it was a minor issue and postponed the inspection. The bearing eventually failed catastrophically, causing a major power outage and significant financial loss.

Lesson Learned: Ignoring warning signs or postponing inspections can lead to disastrous consequences. Proactive maintenance is key to preventing failures.
