A journal bearing is a mechanical device used to reduce friction between moving parts, and it is an essential component of most engines. Engines and other related machinery often make use of many types of bearings, but journal-type models are often best for situations where there is a lot of motion.
A ball bearing is a type of rolling-element bearing that uses balls to maintain the separation between the bearing races. The purpose of a ball bearing is to reduce rotational friction and support radial and axial loads. It achieves this by using at least two races to contain the balls and transmit the loads through the balls.
