- Cylindrical Roller Bearings: Cylindrical roller bearings consist of cylindrical rollers held in place by inner and outer rings, with the rollers positioned parallel to the axis of the bearing. They are designed to primarily support radial loads and provide high rigidity and precision.

   - Spherical Roller Bearings: Spherical roller bearings are designed to primarily support heavy radial loads and moderate axial loads. Their unique design includes barrel-shaped rollers guided by inner and outer ring raceways with a common spherical raceway on the outer ring, allowing them to accommodate misalignment and axial displacement. They are commonly used in applications where heavy radial loads, shock loads, and misalignment are present, such as in heavy machinery, mining equipment, and industrial applications.

   - Needle Roller Bearings: Needle roller bearings feature cylindrical rollers with a much smaller diameter-to-length ratio compared to cylindrical rollers. This design allows for a higher load-carrying capacity in a compact space, making needle roller bearings suitable for applications with limited radial space.

In summary, a cylindrical roller bearing is a critical component in various mechanical systems, providing support for radial loads, high load capacity, rigidity, and precision in a wide range of industrial and commercial applications.

   - Cylindrical Roller Bearings: Cylindrical roller bearings are commonly used in applications where high radial load-carrying capacity and precise radial motion control are essential. They are suitable for machinery and equipment requiring accurate radial load support without significant misalignment.
