Many people don’t understand why SKF imported bearings can’t work under long-term load? This is because if SKF imported bearings work under load for a long time, SKF imported bearings may strike in advance at any time, and some damage that cannot be estimated will occur. Therefore, do not let SKF imported bearings work under load for a long time.
The correct installation of SKF imported bearings is the guarantee for prolonging its service life. Many people do not have professional knowledge in this regard, so they are not particularly in place during installation, which is easy to lead to improper bearing installation and mechanical operation accidents. Therefore, as a professional mechanical maintenance engineer, we must understand the installation of SKF imported bearings. When SKF imported bearing works under long-term load, pay attention to the track of raceway surface
When SKF imported bearings rotates, the raceway surface of the inner ring and outer ring of the bearing is in rolling contact with the rolling element, so the running track is a dark surface. The running track attached to the raceway surface is not abnormal, so the load conditions can be known. Therefore, when removing SKF imported bearing, please pay close attention to and observe the running track of the raceway surface.
If you carefully observe the running track, you will know that it only bears radial load, large axial load, moment load, or extreme uneven rigidity on the bearing housing. It can be checked whether the unexpected load is added to the bearing and whether the installation error is too large, which will become a clue to investigate the cause of SKF imported bearing damage.
Water lubricated bearing is a kind of hardware accessories. I believe many people still have some understanding of the bearing. What is water lubricated bearing? What is the working principle of water lubricated bearing? What is water lubricated bearing?
Water lubricated bearings are divided into phenol bearings, rubber bearings, ceramic bearings, graphite bearings, PTFE and other polymer bearings. The bearing is used directly in water without any sealing device. The bearing is lubricated by water and does not need lubricating oil or grease, eliminating the harm of water pollution. Bearings are often used in flowing water, which can effectively control the bearing temperature rise, so as to have long service life, safety and reliability.
Structurally, it is suitable for horizontal axis, vertical axis and inclined axis. It is mainly used for large industrial water pumps, power plants, nuclear power plants, ships, water turbines, wind power generation, petrochemical industry, light chemical and food machinery, sewage treatment, waterworks, water conservancy pump stations, mining machinery and engineering machinery, valves, mixers and other fluid machinery.
Bearings with water as lubricant are generally sliding bearings. Babbitt alloy used in early water lubricated bearings has long been used in the field of ships, because water can provide hydrodynamic film under certain conditions. Water lubricated bearings are based on self-lubricating materials and combined with the lubricity of water under certain conditions, so as to be used in hydropower stations and other fields.
Water does not have the same high viscosity and lubricity as the recognized lubricant petroleum. Water does have limited viscosity and density, so it can provide hydrodynamic membrane. Skf Imported Bearings The research and development of superior water lubricated bearings will be based on materials and design, which should have good self sliding and excellent friction resistance.
