NTN bearing belong to precision components, so when use requirement has quite cautious attitude that change is used high-performance bearing, if use undeserved, can't reach the expected performance effect, and easy to make bearing damage. So, use the bearing should be pay attention to the following items:

First, maintain NTN bearing and its surrounding environment clean
Even if the invisible to the naked eye dust into the bearing smile, also can add bearing wear, vibration and noise.

Second, use install carefully
Don't allow powerful stamping, allowed to use hammer striking directly bearing, don't allow through transfer roller pressure.

Three, use the appropriate, accurate installation tools
Try to use the specialized tools, avoid to use cloth kind and short fibers, things like that.

Four, prevent bearing the corrosion
Directly with the hand take NTN bearing, want to wash hands full of liquid, and coated with high grade mineral oil again after operation, the summer in the rainy season and pay particular attention to rust.

But, in a special operation conditions, the bearing can obtain a longer than traditional calculation of life, especially in light of the load. These special operation condition is, when the roll surface (rail and rolling a) is a oil film is effectively space and limit pollutants may lead to destruction of the surface. In fact, in the ideal condition, the so-called permanent bearing life is possible.

Bearing quality:
Provide each user NTN bearing secure operation is our ultimate goal, however, only depending on the bearing quality is no guarantee that the functioning of the pillow, there are other factors can affect the life of each bearing period, including:
The operation environment:

The machine equipment if want to play to the best condition. Bearing must have the right to work and avoid a head-on high temperature, humidity and pollution.
The correct installation:
Have the correct installation technology and knowledge and the right tools, can ensure that NTN bearing from harm.
The correct maintenance:
And then the proper lubrication and maintenance plan and bearing condition monitoring work is also play the service life of the highest NTN bearing key.
Worry about running:

Worry about the idea of running is committed to the bearing the correct service and the correct maintenance of the target, the purpose is to have caused because of bearing of down dangerous to lowest, and ensure that all of its potential bearing play. Existing incomplete product and service can help you easy for installation and maintenance work of the bearing.
Bearing life

NTN bearing life to the RPM (or with a certain speed of work is the number of hours), definition: in this life within the bearing, should be in any of its bearing circle or rolling body on preliminary fatigue damage happens (flake or defect). But no matter in lab tests or in be used actually, can be obvious to see, in the same work under the condition of the same appearance bearing, the actual life the same. In addition there are several kinds of different definitions bearing "life", one of the so-called "working life," it said in a bearing damage to life before the actual by wear, damage caused by fatigue is not usually, but by wear and corrosion, seal causes such as damage.
