What is a sliding bearing
Sliding bearings are bearings that work under sliding friction. Sliding bearing works smoothly, reliably and noiseless. Under the condition of liquid lubrication, the sliding surface is separated by lubricating oil without direct contact, which can greatly reduce the friction loss and surface wear, and the oil film also has a certain vibration absorption ability. But the starting friction resistance is larger. The part of the shaft supported by the bearing is called the journal, and the matching part of the journal is called the bearing bush. In order to improve the friction properties of the bearing bush surface and cast on the inner surface of the antifriction material layer called bearing lining. Bearing bush and bearing lining materials are collectively known as sliding bearing materials. The application of sliding bearing is generally in the condition of low speed and heavy load, or in the operation part where maintenance and lubricating oil filling are difficult.
