• Noise: Listen for unusual sounds, such as grinding or squealing, which may indicate bearing failure.
• Uneven Wear: Monitor tire wear patterns for signs of misalignment or suspension issues.

Bearing Troubleshooting

• Excessive Heat: Bearings that are overheating may be under too much load, misaligned, or inadequately lubricated.
• Noise: Unusual noises, such as grinding or squealing, can indicate bearing damage or contamination.
• Vibration: Bearings that are vibrating excessively may be worn, misaligned, or damaged.
  
  

Case Studies

Story 1: The Importance of Wheel Alignment

A trucking company experienced premature tire wear on its fleet of vehicles. After a thorough inspection, it was discovered that the wheels were out of alignment. The company invested in a dedicated wheel alignment machine and implemented a regular alignment schedule. This resulted in significant cost savings by extending tire life and improving fuel efficiency.

Story 2: Predictive Maintenance Saves the Day

A hospital's MRI scanner was experiencing intermittent vibrations that threatened to disrupt patient care. Predictive maintenance software detected an anomaly in the bearing vibration signature and alerted technicians. The bearing was replaced before it failed, preventing costly downtime and ensuring uninterrupted patient care.

Story 3: The Perils of Poor Lubrication

An industrial manufacturing facility experienced repeated bearing failures on its conveyor system. Investigation revealed that the bearings were not being properly lubricated according to the manufacturer's specifications. The company implemented a comprehensive lubrication program and established a training program for maintenance personnel. This resulted in a dramatic reduction in bearing failures and improved overall system reliability.
