linear plain bearings

linear plain bearings work under sliding friction bearings. Sliding bearing work steady, reliable, no noise. Under the condition of fluid lubrication, sliding surface is lubricating oil without direct contact, also can greatly reduce the friction loss and wear of surface oil film also has a certain vibration absorbing ability. But starting frictional resistance is bigger. The mobile crane bearing parts of the shaft are called journal, and shaft neck matching parts called bush. In order to improve the bearing surface of the friction properties and in them on the surface of cast anti-friction material layer is called the bearing bush. Bearing and bearing liner material collectively known as the sliding bearing material. Sliding bearing applications generally under the condition of low speed and heavy loading conditions, or maintenance and charging of lubricating oil is difficult work.
