Rollers are cylindrical bodies on which heavy objects can be placed for easy movement, serving as hard steel cylinders to reduce friction. The rolling surfaces of rollers are spherical. Rollers are primarily used in needle roller bearings, universal joint needle roller bearings, and thrust needle roller bearings, and roller assemblies can also be used directly in machinery.
