What is a sliding bearing?

Sliding bearings, bearings that work under sliding friction. The sliding bearing works smoothly, reliably and without noise. Under liquid lubrication conditions, the sliding surface is separated by lubricating oil without direct contact, and friction loss and surface wear can be greatly reduced. The oil film also has a certain vibration absorption capacity. But the starting frictional resistance is larger. The part of the shaft supported by the bearing is called the journal, and the parts matching the journal are called the bearing bush. In order to improve the friction properties of the bearing pad surface, the anti-friction material layer cast on the inner surface is called the bearing liner. The materials of bearing bushes and bearing linings are collectively referred to as sliding bearing materials. The application of sliding bearings is generally under high-speed and light-load conditions. The advantages of sliding bearings are stable, reliable and noise-free.
