What else needs to be done after the installation of FAG bearings?

After the installation of the FAG bearing is completed, in order to check whether the installation is correct, a running inspection is required.

Small machines can be rotated by hand to confirm whether they are rotating smoothly. Inspection items include: poor operation due to foreign objects, scratches and indentations; unstable torque due to poor installation; poor processing of the mounting seat; excessive torque due to too small clearance; installation errors and seal friction, etc. . wait. If there is no abnormality, the power supply operation can be started.

Large machinery cannot be rotated manually, so after starting with no load, the machine will idling, and then idling, check whether there is vibration, noise, whether the rotating parts are in contact, etc. After confirming that there is no abnormality, input power to operate.

Does the installation of FAG bearings affect the performance and life of the bearings?

Bearings are one of the important parts of construction machinery. Improper installation will affect its use, and even cause engineering machinery and equipment to malfunction.

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

Lubrication has a very important influence on the operation and life of the bearing. Grease is made of base oil, thickener and additives. The performance of grease mainly depends on the base oil. Generally, low viscosity base oils are suitable for low temperature and high speed. High viscosity is suitable for high temperature and high load.

Thickeners are also related to the lubricating performance, and the water resistance of the thickener determines the water resistance of the grease. In principle, different brands of grease cannot be mixed, and even greases with the same type of thickener will have adverse effects due to different additives. The surface of FAG bearing is coated with anti-rust oil. Before installation, it must be carefully cleaned with clean gasoline or kerosene, and then coated with clean high-quality or high-speed high-temperature grease. Fully enclosed FAG bearings do not require cleaning and oiling.

After installing the FAG bearing, if it is not carefully adjusted, the alignment may cause the FAG bearing to bear additional load, 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 measurement. These regular inspections will detect potential problems early and prevent unexpected machine downtime, enable production plans to be realized, and increase plant productivity and efficiency.

During operation, FAG bearings need correct lubrication to improve their performance. The lubrication methods of FAG bearings are divided into grease lubrication and oil lubrication. In order to make FAG bearings play a good function, first of all, we must choose a lubrication method suitable for use conditions and purposes. 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 FAG bearing plunger pumps for hydraulic pumps is the bearings. Reducing the negative pressure in FAG bearings is the basic requirement to prevent water from entering. Angular contact bearing load calculation. Oil supply maintenance of locomotive bearings is very important.
