• Environmental conditions: Factor in exposure to moisture, dust, chemicals, or other environmental factors.

Humorous Stories Involving NTN Bearings

• The Bearing That Saved a Day: A construction crew was frantically searching for a replacement bearing for their crane on a busy highway. As they were about to give up, they stumbled upon an NTN bearing hidden in an abandoned toolbox. The bearing fit perfectly and allowed them to complete their project on time.
• The Dancing Diesel: A mechanic was troubleshooting a diesel engine that was vibrating excessively. After replacing multiple parts, he finally discovered that the vibration was caused by a worn-out NTN bearing in the fuel pump. Installing a new NTN bearing restored the engine to its smooth and quiet operation.
• The Medical Miracle: A surgeon was facing a difficult surgical procedure when his scalpel bearing failed. Fortunately, a nearby medical technician had an extra NTN bearing that he had used in his own robotics project. The surgeon quickly installed the NTN bearing into his scalpel, successfully completing the surgery without any complications.
