Bearings are essential components in numerous industrial applications, such as the automotive, mining and aerospace industries. To identify the type and characteristics of a bearing, acronyms are used that contain specific information about the dimensions and characteristics of the bearing.
The acronym NUP
One of the most common acronyms in cylindrical roller bearings is NUP. This acronym indicates that the bearing has a double rib cage. The cage, or “cage” in English, is a component that keeps the bearing rollers spaced, allowing them to rotate freely. The double ribcage is designed to provide greater rigidity and resistance to deformation of the cylindrical roller bearing.
Other acronyms used in cylindrical roller bearings
In addition to the acronym NUP, there are numerous other acronyms that are used to identify cylindrical roller bearings and their characteristics. For example, the abbreviation NU indicates a cylindrical roller bearing without a cage, while the abbreviation NJ indicates a bearing with only one rib in the cage. There are also abbreviations that indicate the internal diameter of the bearing, such as the abbreviation N, which indicates a bearing with an internal diameter of 50mm.
Conclusion
In conclusion, the acronyms used on bearings are extremely important to identify the type and characteristics of the bearing. The abbreviation NUP indicates that the cylindrical roller bearing has a double rib cage, which gives it greater rigidity and resistance to deformation. Knowing the acronyms used on bearings can help you choose the right bearing for your specific application.
