Bearings - Anti Friction bearings - Roller bearings
 
Video
Roller bearings — also known as rolling-element bearings — are similar to ball bearings in that they are designed to carry a load while minimizing friction. However, roller bearings transmit loads using cylinder rolling elements, rather than balls, to maintain the separation between moving parts of the bearing.

Types of load
They can withstand large radial load and a very little axial (or thrust) load. Typical applications will be ball mills.
