Why The Seal Is Important Spherical Roller Bearings

The tightness of the bearing is to keep the spherical roller bearing in good lubrication conditions and normal working environment, give full play to the bearing's work and performance, and extend the service life. The rolling bearing must have a proper seal to prevent lubricant leakage. And the intrusion of dust, water vapor or other dirt.Bearing seals can be divided into two types: self-contained seals and external seals. Bearing self-sealing is to make the bearing itself into a device with sealing performance, such as bearing belt.This unsealed occupies a small space, is easy to install and disassemble, and has a low price. Bearing external seal is a sealing device with various performances, which is manufactured inside the end cover.

The following factors should be considered when selecting the spherical roller bearing plus seal:Bearing lubricants and types; working environment of the bearing, the size of the occupied space; advantages of the support structure of the shaft, allowable angular deviation; peripheral speed of the sealing surface, operating temperature of the bearing; manufacturing cost.

Thickeners are also related to lubricating oils. Grease and water thickeners determine the resistance of water. In principle, oils and fats are not mixed with different brands. Even thickeners and greases also affect each other due to different additives. Use rust prevention. Oil-coated bearings must be carefully cleaned with gasoline or kerosene, and then coated with clean high-quality or high-speed high-temperature grease.

Spherical roller bearings are installed. If not adjusted carefully, it may lead to more friction and vibration, which may accelerate fatigue, reduce the life of mechanical parts such as bearings, reduce the service life, and greatly increase capacity consumption And premature bearing failure.

During use, it is necessary to monitor the operation of spherical roller bearings, such as temperature, vibration and noise measurement, so that potential problems can be detected early and the machine can be stopped unexpectedly, so that the production plan can be realized and the productivity of the plant can be improved.
During operation, the bearing needs to be relubricated to improve its performance. Bearing lubrication method: Separate grease lubrication from oil lubrication. In order to perform the function of the spherical roller bearing, it is necessary to first select suitable conditions for the purpose of the lubrication method. If only lubrication is considered, oil lubrication predominates.
