GNE50-KRR-B bearings are INA brand of external spherical bearings with eccentric sleeve and lip seal (KRR) structure. This type of bearing is commonly used in industrial equipment scenarios requiring high precision positioning and corrosion resistance, such as: 

metallurgical equipment

Such as rolling mills, blast furnaces, etc., which are used to bear heavy loads and vibrations, while preventing grease leakage or external pollutants from invading.

mining machine

In mining equipment, it is used for shaft adjustment and sealing, adapting to harsh dust and wet environment.

matters need attention:

Ensure the precision of the eccentric sleeve and shaft during installation to avoid bearing deformation caused by excessive tightening.

The sealing ring (KRR) should be checked regularly to prevent failure due to high temperature or aging.
