Several problems needing attention during installation:a. The thickness of inner and outer spacer rings must be matched, and the parallelism of two surfaces of spacer rings shall not exceed 0.002mm.b. Bearings must be optional. The inner diameter differen
The types of machinery are different, the service conditions of bearings will be different, and the performance requirements are not only the same, but generally speaking, there are no less than two bearings on a shaft. Moreover, in order to facilitate ax
Some problems must be paid attention to during polishing operation1. Polishing must be carried out in a clean and dust-free room. Because hard dust particles will contaminate the abrasive material and damage the nearly completed die surface.2. Each polish
According to the relevant data, the damage during the installation of rolling bearings accounts for 20% of the bearing damage. How can we reduce the damage during the installation of bearings? The following is a detailed introduction to the specific requi
In many applications, positive or negative working clearance needs to be added to the bearing configuration. In most applications, the working clearance should be positive, but it also needs to be negative in many cases, such as machine tool spindle beari
Precision bearings are divided into P0, P6, P5, P4 and P2 according to the grading standard of ISO. The grades increase successively, in which P0 is ordinary precision and other grades are precision grades. Of course, different classification standards an
During use, the basic external conditions of bearing operation shall be monitored frequently, such as temperature, vibration and noise measurement. These regular inspections will identify potential problems as soon as possible, prevent unexpected machine
Installation and disassembly method of outer spherical ball bearing with seat:1、 Installation of outer spherical ball bearing with seat:a. Put the bearing into the installation notch of the seat;b. After rotating the bearing slightly, insert a wooden rod
In addition to the functions of lubrication, cooling, cleaning, sealing, protection and buffer, the working environment of bearing lubricating oil is also very bad.1. During splash and circulating lubrication, lubricating oil is constantly in contact with
The method of improving the bearing stiffness of fan.1) The lower the surface roughness and the better the shape and position accuracy of the bearing installation position on the shaft and seat hole, the higher the support rigidity.The surface strengtheni
