Interesting Stories and Learnings

The Case of the Overzealous Engineer

A young engineer at one of NTN's manufacturing facilities was so enthusiastic about his work that he decided to skip the final inspection step on a batch of bearings. When the bearings were installed in a high-performance race car, they failed catastrophically, causing the car to crash.

Lesson learned: Never compromise safety or quality, regardless of time pressures.

The Curious Case of the Squeaky Bearing

A customer complained to NTN about a persistent squeaking noise coming from a bearing in their industrial machinery. After several unsuccessful attempts to fix the issue, a technician discovered that the bearing was being lubricated with the wrong type of grease. Once the correct grease was used, the squeaking noise disappeared.

Lesson learned: Proper lubrication is essential for bearing performance.

The Not-So-Smooth Ride

A bus company experienced a high rate of bearing failures on their front wheels. After investigating, NTN engineers discovered that the buses were being operated on roads with numerous potholes and uneven surfaces. The excessive impact caused the bearings to experience premature wear.

Lesson learned: Bearings should be selected and used in accordance with the operating conditions they will encounter.
