Name one common type of bearing used in machinery.

Ball bearings are widely used in various machinery and applications due to their ability to reduce friction between moving parts. They consist of a set of spherical balls that are positioned between two rings, known as races. As the inner race rotates, the balls roll along the surface of both the inner and outer races, allowing for smooth and efficient motion with minimal resistance.

This design not only enables them to support both radial and axial loads but also allows for high rotational speeds, making ball bearings suitable for a wide range of uses, from automotive applications to household appliances. Their versatility and effectiveness in reducing wear and tear make them one of the most common types of bearings in the industry.

While roller bearings, thrust bearings, and magnetic bearings each have their specific uses in various applications, ball bearings remain the most commonly encountered type in everyday machinery, largely due to their simplicity and efficiency.
