Rolling Process: Types, Working, Terminology and ...

Ring rolling is an another method of rolling which is used to rolled rings of large bearings, turbines etc. In this process, two rollers (Main Roller and Idler Roller) are arranged as shown in figure and rotate in same direction to each other. The ring rotates due to rotation of roller and the rollers start move closer to each other.


Rolling bearings generally consist of two rings, rolling elements, and a cage, and they are classified into radial bearings or thrust bearings depending on the direction of the main load. In addition, depending on the type of rolling elements, they are classified into ball bearings or roller bearings, and they are further segregated by

Roller dam - Wikipedia

Roller dams are a type of weir, or a dam that is designed to allow water to flow over the top in continuous action. They are used on rivers or other such moving bodies of water where erosion damage is undesirable, yet likely to occur. A short wall, lip, or parabolic channel is constructed on the downstream side of the dam parallel to the dam face.
