A roller bearing is also called a cylindrical roller bearing because of the cylindrical rolling elements. Due to their durability, roller bearings are used in metalworking machines and widely understood industrial machines. They are characterized by high axial load capacity and a separate structure. This means that at least one of the rings has no track. If high-quality steel is used in the bearings and proper operation is maintained, roller bearings can serve us for up to 30 years.
