Needle Roller Bearing Principle? Installation Techniques?

- Mar 21, 2018 -

Whether a bearing a needle roller bearing or not, we can observe whether the inside of bearing has a needle roller. 

If there is a roller bearing, this iconic roller is called a needle roller bearing. 

Because the roller is long and slim, relative to the diameter of the needle roller bearing.

Physical sense tells us that objects with small cross-sections generally have very limited loads. 

However, although the cross section of this needle roller bearing is very small, its ability to load is still outstanding. Therefore, such non-standard bearings are frequently used in many places where space is narrow or limited.


If the needle roller bearing can be operated freely in one direction and locked in the other direction, then we call it a one-way needle roller bearing, which is a special bearing different from non-standard bearings. 

used in Mechanical equipment widely. 

Its classification can be defined upon the latter coefficient of the metric coefficient. There are many different types of needle roller bearings for each type of coefficient.
