Plane spherical bearing characteristics interpretation and installation precautions

- Aug 06, 2018-

Plane spherical bearings are mainly subjected to axial loads during operation and are widely used. This series of bearings uses a unique flat bearing channel super-finishing technology to improve the performance of the bearing. At the same time, high-speed hot-twisting forging technology was used in the production to improve the material utilization rate by 18%, and a low-noise and long-life flat spherical bearing was produced.


In addition, when the cage of the spherical spherical bearing is processed, the surface is specially subjected to a new process of hydrogen nitriding, which can increase the tensile strength of the cage by 64%. Although the installation method of this type of bearing is relatively simple, there are often problems in the actual maintenance operation. The most common one is that the tight ring and loose ring of the bearing are not installed correctly. As a result, the bearing does not operate normally, and the journal is quickly it's broken.


In order to avoid such problems, we should at least meet the three requirements: First, distinguish the tight ring and loose ring of the plane spherical bearing (according to the inner diameter of the bearing, the hole diameter difference is O.1 ~ O.5mm); second, distinguish The stationary part of the mechanism (ie the part that does not move, mainly refers to the assembly); third, the loose ring of the bearing should always rest on the end face of the stationary part.
