The ball bearing is a mechanical gearbox's most important component. It connects the roller to the inner and outer rings and hangs from the rotator to support the revolving parts. This technique allows for the transmission of both electricity and motion. In this paper, rolling bearings are commonly used to reduce rotational motion friction. The parts include rings, folding pieces, and cages. A ball bearing is made up of solid, spherical balls that rotate between two surfaces and reduce friction. A ball bearing's main functions are to support radial and axial loads and to lessen rotational friction. In this work, emphasis has been given to the design of bearings based on variables such as bore diameter, depth, and load ratings for both dynamic and static loads. A three-dimensional model of the ball bearing was created using CATIA. High-stress regions were identified, and design modifications were recommended if appropriate. because to determine bearing life, rotational speed and load parameters are also used.
