CYLINDRICAL ROLLER BEARING
Cylindrical roller bearings refer to radial roller bearings with cylindrical rollers as rolling elements. We classify them based on the number of roller rows and the presence or absence of flanges on the inner and outer rings, and introduce several common types of cylindrical roller bearings.

Most cylindrical roller bearings are single-row and separable, making installation and disassembly relatively convenient. They generally can only bear pure radial loads. Compared with deep groove ball bearings of the same size, they have a higher radial load capacity. However, they require high machining accuracy of the shaft and housing inner. The permissible deviation of the alignment between the inner and outer ring axes is 2′ to 4′, and they are used for shafts with greater rigidity. A small amount of axial displacement is allowed in the direction without flanges, while the side with flanges on the inner or outer ring can bear a certain amount of axial load. Bearings with the suffix “E” are reinforced cylindrical roller bearings. These are optimized designs with more rollers, longer rollers, and larger diameters, resulting in higher load capacity and should be given priority.
