How to extend lifetime of TIMKEN Deep Groove Ball Bearing?

TIMKEN bearing contact fatigue failure is the bearing surface by alternating the role of stress arising from failure, and deep contact fatigue spalling is to generate the underlying causes of failure.
We know that the contact fatigue spalling occurred in the deep groove ball bearing surface, often accompanied by fatigue crack, the first from the contact surface the following maximum alternating shear stress generated at, and then extended to the surface of different peeling shapes, such as point-like to point pitting corrosion or peeling, flaking into small pieces is called superficial peeling. As the peeling surface gradually expanded, and often extend to the deep, the formation of deep peeling.
Wear failure refers to the relative surface sliding friction between the working surface of the metal lead to constant wear and tear resulting from the failure.
Continuing the gradual wear and tear will cause damage to the bearing parts, and eventually lead to loss of dimensional precision bearings and other related issues. Wear may affect the shape change, with the gap increasing and work surface morphology, or it may affect the lubricant contamination to a certain extent complete loss of function caused by lubrication, thereby bearing the loss of rotational accuracy and even can not operate normally. Wear all kinds of bearing failure is a common failure mode, one can generally be divided according to wear the most common form of abrasive wear and adhesive wear.
TIMKEN bearings TIMKEN bearing fracture failure is mainly due to defects and the use of their own when overload
When the applied load exceeds the ultimate strength of materials, parts breakage as a result of overload fracture. The main reason is the host overload sudden failure or improper installation. Bearing parts of the micro-cracks, shrinkage, air bubbles, large foreign debris, overheating and partial burns and other tissue defects in severe shock or vibration overload will cause fracture in the defects, called flaws fracture. It should be noted, bearing in the manufacturing process, raw materials into the plant for re-inspection, forging and heat treatment quality control, process control equipment can be properly analyzed by the existence of these defects, the control must be strengthened in the future. But in general, deep groove ball bearings usually appear most of the overload fracture failure failure.
1) Keep clean the bearing and the surrounding
2) the use of carefully carefully
If the reckless use of a strong shock to the bearing, the bearing will appear scars, indentation, fracture and other injuries.
3) Use the right tools
4) Note that the anti-rust bearings
Avoid use in wet locations, but also not to sweat stained, should wear gloves.
5) Users should be familiar with the bearing
6) the development of deep groove ball bearings operating specifications
a, bearing in custody
b, cleaning the bearing and the surrounding
c, install parts of the size and processing quality of the test
d, installation
e, after installation check
f, demolition work
g, maintenance (periodic inspection)
h, add lubricant
