Bearing belong to precision parts, 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 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 bearing, want to wash hands full of sweat, 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 life

The rolling bearing life to turn number (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.
