    Impact of angular contact ball bearings on use

    The shaft parts of the machine tool, especially the main shaft, are generally assembled into a thrust ball bearing and rotate at a high speed, sometimes generating high heat. If this phenomenon is not ruled out in time, it will cause angular contact ball bearings to overheat and increase the temperature of the corresponding parts of the machine tool, resulting in thermal deformation. In severe cases, the spindle and ...

    Analysis of noise characteristics of imported bearings

    The high-quality 6203 imported bearing raceway sound is 25-27dB. This type of noise is most typical of single-row deep groove ball imported bearings that support radial loads. It has the following characteristics: 1. When the radial clearance increases, the sound pressure level increases sharply; 2. The vibration frequency is above 1kHz; 3. The higher the viscosity of the lubricant, the lower the sound pressure leve...

    Steps for installing bearings by heating

    Installing the bearing for heating is a method. This heating method can reduce bearing wear and improve installation efficiency.The principle of the heating method is to use thermal expansion to heat the bearing inner ring, and the NSK bearing can be installed when it reaches a safe expansion temperature. The main steps are as follows: 1. Bearing cleaning, put the bearing in a gasoline-filled cleaning box, wear rubbe...
