Ball bearing meaning
The term “ball bearing” refers to a type of rolling-element bearing that utilizes small, spherical balls to reduce friction and support the smooth rotation of machine parts. Ball bearings consist of two rings, an inner ring (inner race) and an outer ring (outer race), with the balls positioned between them.
The design allows for the distribution of radial and axial loads, making ball bearings widely used in various applications across different industries.The rolling action of the balls between the rings minimizes friction, enabling machinery to operate efficiently while reducing wear and heat generation.
Ball bearings are crucial components in a wide range of devices, from household appliances to industrial machinery.
