FAG Bearing Installation affect Bearing Working Life

Writer: Eric Bearing Limited

Bearings are one of the important components on construction machinery. Poor installation will affect their use and even cause failure of construction machinery equipment.

If foreign materials such as iron filings, burrs, and dust enter the FAG bearing, it will cause noise and vibration during operation of the FAG bearing, and may even damage the raceway and rolling elements. Therefore, before installing FAG bearings, the installation surface and the installation environment must be clean.

Lubrication has a very important effect on the operation and life of bearings. Grease is made from base oil, thickener and additives. The performance of the grease is mainly determined by the 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.

Thickener is also related to lubricating performance, the water resistance of the thickener determines the water resistance of the grease. In principle, greases of different brands cannot be mixed, and even greases of the same type of thickener can cause bad effects due to different additives. The surface of the FAG bearing is coated with anti-rust oil. It must be carefully cleaned with clean gasoline or kerosene, and then coated with clean high-quality or high-speed high-temperature lubricating grease before installation. Fully enclosed FAG bearings do not need to be cleaned and oiled.  FAG B7208-C-T-P4S-UL bearings online :

After the FAG bearing is installed, if it is not carefully adjusted, the alignment may cause the FAG bearing to suffer additional loads, friction and vibration. These may accelerate fatigue and reduce the service life of FAG 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 FAG bearing operation must be monitored frequently, such as temperature, vibration and noise measurements. These regular inspections will detect potential problems early and will prevent unexpected machine stoppages, enable production planning to be realized, and increase plant productivity and efficiency.

During operation, FAG bearings require correct relubrication to perfect its performance. The method of FAG bearing lubrication is divided into grease lubrication and oil lubrication. In order to make FAG bearings function well, first of all, it is necessary to choose a lubrication method suitable for the conditions of use and purpose of use. If only lubrication is considered, the lubricity of oil lubrication is dominant. But grease lubrication has the advantage of simplifying the structure around FAG bearings.

The most important component of the FAG bearing plunger pump for hydraulic pumps is the bearing. Reducing the negative pressure in the FAG bearing is the basic requirement to prevent water from entering. The load calculation of the angular contact bearing. The oil supply maintenance of the locomotive bearing is very important.
