Influence Of Ntn Bearing Installation On Bearing Performance And Service Life

Influence Of Ntn Bearing 

NTN bearing is one of the important parts of construction machinery. Poor installation will affect its use effect Influence Of Ntn Bearing and even cause the failure of construction machinery equipment.

If there are iron filings, burrs, dust and other foreign matters in the bearing, the bearing will produce noise and vibration during operation, and even damage the raceway and rolling Influence Of Ntn Bearing element. Therefore, before installing the bearing, it is necessary to ensure that the installation surface and installation environment are clean.

Lubrication has a very important impact on the operation and service life of NTN bearings. Grease is made Influence Of Ntn Bearing of base oil, thickener and additives. The performance of grease is mainly determined by base oil. Generally, low viscosity base oil is suitable for low temperature and high speed; High viscosity is suitable for high temperature and high load.

The water resistance of thickener determines the water resistance of grease. In principle, greases of Influence Of Ntn Bearing different brands cannot be mixed, and even greases with the same thickener will have bad effects on each other due to different additives.

The bearing surface is coated with antirust oil, which must be carefully cleaned with clean gasoline or Influence Of Ntn Bearing kerosene, and then coated with clean high-quality or high-speed and high-temperature lubricating grease before installation and use. Totally enclosed bearings do not need to be cleaned and oiled.

Influence Of Ntn Bearing Installation On Bearing Performance And Service Life

After the NTN bearing is installed, if it is not carefully aligned, the alignment may cause the bearing to suffer additional load, friction and vibration. These may accelerate fatigue and reduce the service life of bearings, and may damage the service life of other machine parts. In addition, increased vibration and friction may greatly increase energy consumption and the risk of premature failure.

During use, the basic external conditions of bearing operation shall be monitored frequently, such as temperature, vibration and noise measurement. These regular inspections will identify potential problems as soon as possible, prevent unexpected machine suspension, realize production plans and improve plant productivity and efficiency.

During operation, the bearing requires correct re lubrication to perfect its performance. The lubrication methods of NTN bearings are divided into grease lubrication and oil Influence Of Ntn Bearing lubrication. In order to make the bearing function well, first of all, choose the lubrication method suitable for use conditions and purposes.

If only lubrication is considered, the lubricity of oil lubrication is dominant. However, grease lubrication has the Influence Of Ntn Bearing advantage of simplifying the structure around the bearing.

All NSK Bearings require small working clearance. You must select the appropriate clearance according to the conditions.

In the national standard 4604-93, the radial clearance of rolling NSK bearing is divided into five groups – group 2, group 0, group 3, group 4 and group 5. The clearance value increases from small to large, of which group 0 is the standard clearance. The basic radial clearance group is suitable for general operating conditions, conventional temperature and common interference fit;

NSK Bearings working under special conditions such as high temperature, high speed, low noise and low friction should choose large radial clearance; Small radial clearance should be selected for precision spindle and NSK bearing for machine tool spindle;

A small amount of roller bearing clearance can be maintained for NSK. In addition, there is no clearance for separate NSK Bearings; After installation, the working clearance of NSK bearing after installation is smaller than the original clearance before installation, because NSK bearing has to bear certain load rotation, as well as the elastic deformation caused by NSK bearing matching and load.
