Roller Bearings

Roller bearings are mechanical components designed to reduce friction and facilitate smooth rotation or linear motion. They consist of an outer ring, an inner ring, and rolling elements (like cylinders or spheres) that are placed between these rings. The rolling elements help to carry loads and reduce friction between moving parts by rolling rather than sliding. 

Types of Roller Bearings: Cylindrical Roller Bearings,Spherical Roller Bearings,Tapered Roller Bearings,Needle Roller Bearings,Thrust Roller Bearings.
