When the lubrication effect of the coupling and the bearing bush fails to meet the requirements, a variety of failure characteristics will appear.If the oil pressure is low, the direct contact between the shaft and the bearing shell will cause dry friction to cause damage and damage to the moving surface. At this time, the shaft surface is blue.If the lubricating oil fails or the pressure cannot be built up, the moving surface completely loses the protection of the oil film and directly contacts for dry friction. .In addition to economy, the repair of the coupling has its technicality, which requires the repairer to fully understand the corresponding technical requirements of the bearing, and the characteristics of the bearing and its parts in the structure, process and materials, otherwise it is difficult to guarantee the repair of the bearing. There are satisfactory results.The main material factors that affect the service life of high-carbon chromium steel rolling bearing parts and the degree of control are.

　　When ordering a coupling, if the coupling you need is a standard coupling, the main data provided to us is the diameter and length of the shaft hole of the half coupling.If the coupling you need is not a standard coupling, you need to provide us with the diameter and length of the shaft hole of the half coupling, other than the standard size of the standard coupling, such as the key depth and keyway Key width, large outer diameter and small outer diameter, etc.If there are drawings for the coupling you need, please send the drawings to us, so that we can customize the coupling model and size for you according to the requirements of your drawings.
