NTN bearings are known for their high quality and reliability, and they are widely used in various industries. However, using bearings improperly or without proper precautions can lead to damage and failure, which can result in costly downtime and repairs. In this article, we will discuss the proper usage and precautions for NTN bearings to ensure optimal performance and longevity.


Proper handling: NTN bearings should be handled with care and kept in their original packaging until they are ready to be installed. Avoid dropping or hitting the bearings, as this can cause damage to the raceways, rolling elements, and cages. In addition, do not expose the bearings to dust, dirt, moisture, or extreme temperatures, as these can also cause damage.

Correct mounting: NTN bearings must be mounted correctly to ensure optimal performance. Use appropriate mounting tools and follow the recommended procedures for mounting the bearings onto the shaft and housing. It is also important to use the correct lubricant and apply it in the recommended quantity and frequency.

Proper alignment: Proper alignment of the shaft and housing is critical for NTN bearings. Misalignment can cause excessive load on the bearings and lead to premature failure. Make sure the shaft and housing are aligned according to the manufacturer’s recommendations.

Regular maintenance: Regular maintenance is important for NTN bearings to ensure long-term performance. This includes inspecting the bearings for signs of wear, checking the lubricant level and quality, and cleaning the bearings and surrounding areas.


Avoid overloading: NTN bearings are designed to handle specific loads and overloading can cause damage and premature failure. Make sure to calculate the loads and select the appropriate bearings for the application.

Avoid shock loads: Shock loads can cause excessive stress on the bearings and lead to failure. Make sure to design the application with shock loads in mind and select bearings that can handle these loads.

Avoid contamination: Contamination can cause damage to the bearings and reduce their lifespan. Make sure to keep the bearings and surrounding areas clean and free of debris, and use appropriate seals and shields to prevent contamination from entering the bearing.

Avoid overheating: Overheating can cause damage to the bearings and lead to premature failure. Make sure to monitor the temperature of the bearings during operation and ensure proper lubrication and cooling.

In conclusion, using NTN bearings properly and with proper precautions is essential for optimal performance and longevity. By following the guidelines outlined in this article, you can ensure that your NTN bearings will perform at their best and provide reliable service for years to come.
