How to choose the bearing sealing method suitable for specific application scenarios

The selection of bearing sealing methods suitable for specific application scenarios requires consideration of the following factors:
1. Working environment: If there is a large amount of dust, moisture, or corrosive substances in the working environment, it is necessary to choose a contact sealing method with good sealing performance to prevent these impurities from entering the interior of the bearing.
2. Speed requirements: If there is a high requirement for the speed of the bearing, it is necessary to choose a non-contact sealing method to reduce the friction resistance between the sealing element and the bearing, and increase the speed of the bearing.
3. Lubricant type: Different lubricant types have different requirements for sealing methods. For example, oil lubricants require the selection of contact sealing methods with good sealing performance, while oil lubricants can choose non-contact sealing methods.
4. Temperature requirements: If the working environment temperature is high, it is necessary to choose sealing materials and structures that can withstand high temperatures to ensure the normal operation of the bearings.
5. Cost considerations: Different sealing methods also have different costs. When choosing a sealing method, it is necessary to consider cost factors and choose the sealing method with the highest cost-effectiveness.
In summary, selecting a bearing sealing method suitable for specific application scenarios requires comprehensive consideration of the above factors and selection based on specific circumstances. If unsure how to choose, you can consult a professional bearing manufacturer or technical personnel.
