NTN bearings are commonly used in various industries, including automotive, aerospace, construction,
and mining. Proper use and maintenance of NTN bearings can extend their lifespan and improve
equipment performance. In this article, we will discuss the usage methods and precautions for NTN
bearings.
Usage methods:
Bearing installation: Before installation, the bearing and the installation parts must be cleaned,
and the bearing should be inspected for cracks, wear, and damage. The installation surface should be
flat and clean, and the mating surfaces should fit tightly without gaps. The bearing should be
installed in the correct position, and the installation method should be selected based on the
bearing type, size, and precision requirements.
Lubrication: NTN bearings must be properly lubricated to reduce friction and prevent premature wear.
The type and amount of lubricant depend on the operating conditions and bearing type. Grease
lubrication is the most commonly used method, and the appropriate grease should be selected based on
factors such as operating temperature and load. The lubrication interval should also be determined
according to the operating conditions.
Bearing maintenance: Regular maintenance can help detect problems early and prevent bearing failure.
The bearing should be inspected periodically for signs of wear or damage, and the lubricant should
be replenished or replaced as needed. If the bearing needs to be removed for maintenance, it should
be handled carefully to avoid damage.

Precautions:
Handling and storage: NTN bearings should be stored in a dry, clean, and dust-free environment to
prevent rust and contamination. When handling bearings, avoid dropping or striking them, and use
appropriate tools and equipment to avoid damage.
Temperature and humidity: Excessive heat or cold can cause the bearing to expand or contract,
leading to premature failure. The operating temperature range should be within the specified limits,
and the bearing should not be exposed to extreme temperature or humidity conditions.
Load and speed: The bearing should be operated within the specified load and speed limits to avoid
excessive wear and fatigue. The load and speed should be determined based on the bearing type, size,
and application requirements.
In summary, NTN bearings are widely used in various industries and can provide reliable and long-
lasting performance when used and maintained correctly. By following the proper usage methods and
precautions, equipment operators can extend the lifespan of NTN bearings and improve equipment
performance.
