Marine bearing bush is also called "sliding bearing". For example, a sliding bearing made of copper is lubricated by the oil groove on the friction surface of the copper tile, which plays a similar "supporting" role as a ball bearing and reduces the friction force of the shaft. The following bearing manufacturers specifically introduce the difference between marine bearing and bearing.
The bearing bush manufacturer reminds that there are many types of bearings, and the bearing bush is a sliding bearing. This type of bearing is relatively stable, and will not be easily damaged, and is more reliable. Secondly, it has no noise. After adding lubricating oil, there is a layer of medium oil between the two working surfaces, which can greatly reduce friction loss and surface wear.
In addition, the bearing manufacturer suggested that the oil film has the ability to absorb vibration, but the friction is a bit high when it is just started. In this kind of bearing, the part supported by the shaft and the bearing is called the journal, and the marine bearing is matched with the journal. Of course, this kind of bearing is rare in general places, only those places where the speed is not very fast and the negative pressure is high will be used.
Marine bearing bush bearings are generally composed of inner and outer rings, rolling elements and cages. The inner ring of the inner layer is responsible for connecting with the main shaft and rotating together. The bearing manufacturer reminds that the outer ring of the marine bearing bush is mainly the base of the bearing. Combined use, play a load-bearing role. The rolling element of the marine bearing bush is a shaft that rolls between the inner and outer rings. Its shape, size and quantity directly affect the life of the bearing. As long as the bearing can be kept evenly distributed, it can prevent the rolling element from falling off and play a role in guiding the rolling element lubrication.
