Advantages Of Needle Roller Bearings

What is needle roller bearing
Needle roller bearings are roller bearings with cylindrical roller, relative to its diameter, the roller is thin and long.This type of roller is called a needle roller.
Points for attention when using needle roller bearings
Needle roller bearing has a large bearing capacity and is suitable for mounting the supporting structure with limited size. The surface of the journal is hardened as the rolling surface, and the bearing is loaded into the seat hole with pressing fit, and there is no need to position it axially.Bearings should be injected with appropriate amount of grease before installation, usually, after assembly, no more lubrication type bearings used in the journal without protruding end of the support, end face closure plays a sealing role, and can withstand small axial swimming.
Cause of damage of needle roller bearing
In general, needle roller bearing damage is caused by fatigue damage, poor lubrication, contaminants entering the bearing or improper disposal of equipment.Dust cleaning bearings and the surrounding environment, invisible to the naked eye fine dust is a powerful killer of bearings, it can increase the wear, vibration and noise of bearings.Stamping in the use of equipment to form a strong stamping, it is very likely to lead to needle bearing damage or the use of hammer directly hit the bearing, through the rolling body transfer pressure.The impact of the installation of non-professional tools With suitable, accurate equipment, you can try to avoid the use of things like cloth and staple fibers.Needle roller bearings whether in the laboratory test or in practical use, it can be clearly seen that the appearance of the same needle roller bearings under the same operating conditions, the actual life of the needle roller bearings is very different.

Advantages of needle roller bearings
1. Needle roller bearings have realized standardization, serialization and generalization, which are suitable for mass production and supply, and are very convenient for use and maintenance.
2. Needle roller bearing with bearing steel manufacturing, and after heat treatment.Therefore, needle roller bearings not only have higher mechanical properties and long service life, but also can save the non-ferrous metals which are more expensive to manufacture sliding bearings.
3. The internal clearance of needle roller bearing is very small, and the machining accuracy of each part is high, so the running accuracy is high.At the same time, the rigidity of the bearing can be increased by preloading.This is very important for precision machinery.
4. Some needle roller bearings can bear radial and axial loads at the same time, so the structure of bearing bearings can be simplified.
5. Because of the high transmission efficiency of needle roller bearing, less heat, so can reduce the consumption of lubricating oil, lubrication maintenance is more convenient.
6. Needle roller bearings can be conveniently applied to the shaft in any direction in space.
