NSK bearings in the middle of use, bearing problems is a very common thing. Many people in the course of using, without attention to some issues, it is easy to cause early bearing damage.
We all know installed later to detect bearing accuracy of NSK bearings, often use different NSK bearing accuracy requirements are also different, this requires us to on its accuracy of menstrual regulation.
1, all kinds of cracks, cracks such as raw materials, forging crack, cracks and grinding crack of heat treatment and so on, in the operation of those cracks in bearing, becomes a source of stress concentration and the rapid expansion, resulting in rupture of the bearing, great on NSK bearing life and job security.
2, all kinds of mechanical injuries, such as Strip, scratched, bruised, scratches, etc will have poor NSK bearing install, caused by eccentric load and stress concentration, causing rotation accuracy and use declining life expectancy.
3, from the skin and collapse, both local and loose substrate with metal defects, and often exist to varying degrees around it and decarbonization phenomena of poverty or carbon, materials easy caving, Dent or wear, on the life of NSK bearings and precision at a disadvantage.
4, rust, dark-skinned and pitting, the latter two are easy to store moisture and dirt defects, most likely to develop into rust. While rust is leading to poor installation, sources of early wear and fatigue, severe corrosion of NSK bearing scrap.
5, cage's riveting or welding quality, main observation on the rivet head deviation, skew, relaxation, lack meat or "double fold ', welding is properly seated, solder is too big or too small, there is any loose weld or solder stuck rolling caused by excessive phenomenon.
