Bearing vibration damage should pay attention to several major issues
Generation of vibrations in bearings Generally speaking, rolling bearings themselves do not generate noise. What is often perceived as “bearing noise” is actually the acoustic effect of the bearing vibrating directly or indirectly with the surrounding structure. This is why many times...Read more -
The accuracy of precision bearings after installation
Introduce the accuracy of precision bearings after installation 1. Accuracy improvement method After the bearing is installed in the main engine, if the radial runout of the main shaft is measured, it can be found that the measured value of each revolution has a certain change; when the measureme...Read more -

Features and applications of tapered roller bearings
Features of tapered roller bearings Tapered roller bearings are separable bearings, the inner and outer rings of the bearing have tapered raceways, and the rollers are truncated. The roller and the raceway are in line contact, which can bear heavier radial and axial combined load, and can also be...Read more -
How to measure bearing axial clearance
How to measure bearing axial clearance When selecting bearing clearance, the following aspects should be considered: 1. The working conditions of the bearing, such as load, temperature, speed, etc.; 2. Requirements for bearing performance (rotational accuracy, friction torque, vibration, noise); ...Read more -
