Roller Bearings: Roller bearings utilize cylindrical or tapered rolling elements (rollers) to support heavy radial and axial loads. They are commonly found in heavy machinery, industrial equipment, and automotive components that require high load capacity and shock resistance. Roller bearings are used in applications such as conveyor systems, gearboxes, large industrial fans, and construction equipment.

   - Spherical Roller Bearings: Spherical roller bearings are designed to support heavy radial loads, as well as moderate axial loads, and are capable of accommodating misalignment. 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.
