Three Common Senses when Installing Rolling Bearings

1. The requirements of rolling bearings on the installation surface and installation place. 

If there are foreign objects such as iron filings, burrs, dust, etc. in the bearing, it will cause noise and vibration during the operation of the bearing, and even damage the raceway and rolling elements. Therefore, before installing the bearing, you must ensure that the installation surface and installation environment are clean.

2. Bearings must be cleaned before installation. 

The bearing surface is coated with anti-rust oil. The roller bearing or ball bearing must be carefully cleaned with special clean gasoline or kerosene, and then coated with clean, high-quality or high-speed and high-temperature lubricating grease before installation and use. The impact of cleanliness on bearing life and vibration noise is very large. Note that fully enclosed bearings do not need to be cleaned and refueled.

3. Choose the right grease. 

Lubrication has a very important influence on the operation and life of bearings. Grease is made of base oil, thickener and additives. Different types and grades of grease have different performances and different allowable rotation limits. Please refer to the performance of the base oil when selecting. Generally, the low viscosity base oil is suitable for low temperature and high speed; the high viscosity base oil is suitable for high temperature and high load. The thickener is also related to the lubricating performance, and the water resistance of the thickener determines the water resistance of the grease. Note that different brands of grease cannot be mixed, and neither old and new greases. At the same time, when lubricating the bearing, the grease should be appropriate, too much or too little is not good for the bearing.

Doing the above points can basically solve some problems when installing rolling mill bearings. If you have more questions, please consult our FV bearings, we will give you professional answers.
