The Use of INA Stamping Outer Ring Needle Roller Bearings

Writer: Eric Bearing Limited

In addition to the high quality, the drawn outer ring needle roller bearings are also very precise parts. Both are high-performance INA drawn outer ring needle roller bearings. If they are used improperly in the use process, they will not only fail to achieve the expected performance results, but also easy Everyone must have paid attention to the lubrication of the drawn outer ring needle roller bearings.

In order to make the service life of stamped outer ring needle roller bearings longer, INA bearings use the method of prolonging the life cycle, I hope it can help everyone.

1. Installation of needle roller bearings with drawn outer ring

The correct installation of the drawn cup needle roller bearings affects accuracy, life, and performance. Therefore, the design and assembly department should fully study the installation of INA stamping outer ring needle roller bearings. Hope to install according to the operation standard. The work standard items are usually as follows:

(1) Cleaning bearings and bearing related parts;

(2) Check the dimensions and finishing of related parts;

(3) Installation;

(4) Inspection after installing the bearing;

(5) Supply lubricant.

2. Adjust and straighten

After the INA stamped outer ring needle roller bearing is installed, if the alignment is not carefully performed, 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 can greatly increase energy consumption and the risk of premature failure.  INA NKS 24 bearings online , pls click here :

Under certain special operating conditions, stamped outer ring needle roller bearings can achieve a longer life than traditional calculations, especially under light loads. 

These special operating conditions are when the rolling surfaces (tracks and rolling elements) are effectively separated by a lubricant film and limit the surface damage that can be caused by contaminants. In fact, under ideal conditions, the life of so-called permanently drawn outer ring needle roller bearings is possible.
