SKF Teaches You How to Select and Use Bearings
Source: China Bearing Network | Date: April 3, 2013
Bearings are not just rolling elements; they also include other components such as shafts, housings, and lubricants. Lubricants play a crucial role in the performance of bearings by reducing friction and preventing wear and corrosion. Seals are equally important, as they protect the lubricant from contamination, ensuring its cleanliness and effectiveness. Maintaining proper hygiene is essential for extending the life of bearings, which is why SKF offers comprehensive solutions that include lubricants and seals. Selecting the right bearing involves more than just choosing the correct type and size. Several other factors must be considered, such as: - The proper installation and alignment of other components in the system - Correct fit, internal clearance, or preload of the bearing - Proper mounting techniques - Appropriate sealing methods - Type and amount of lubricant used - Methods for installation and removal Each of these factors directly impacts the performance, reliability, and cost-effectiveness of the bearing system. The level of effort required depends on the experience and knowledge of the person selecting the bearing. If there's a lack of experience, specific requirements, or budget constraints, additional research, calculations, or testing may be necessary. In the following chapters, we will guide you through the basic information needed for general bearing applications. However, it’s important to note that not all application-specific details can be covered in one place. That’s why SKF provides expert engineering support services, helping with accurate bearing selection and technical assistance for proper installation and maintenance. The information provided here generally applies to standard rolling bearings or groups of similar bearings. For specific bearing requirements, detailed information can be found in the corresponding sections before each classification table. Keep in mind that the load and speed values listed in product tables are rounded approximations. Always refer to official specifications for precise data.
