A roller bearing is a bearing which carries a load by placing rolling elements (rollers or balls) between two bearing rings called races.
Types of roller bearings
● Cylindrical roller Bearing - They handle low thrust and high radial loads at high speeds.
● Spherical Roller Bearings - They have two rings on the inner raceway that handle loads and misalignment concerns
● Needle Roller Bearings - They use long and thin cylindrical rollers for supporting radial loads.
● Tapered Roller Bearings - They have tapered outer and inner rollers and raceways to accommodate the simultaneous thrust and radial loads.
