How can we use cylindrical roller bearings correctly?

Cylindrical roller bearings, like other types of bearings, are also divided into different categories. How to choose the type has once become the most frequently asked question by our engineers. In order to let everyone know more about cylindrical roller bearings, the following will give you a detailed explanation of the types and characteristics of cylindrical roller bearings.

What are the commonly used methods for adjusting the radial clearance of full complement cylindrical roller bearings?

The commonly used methods for adjusting the radial clearance of full complement cylindrical roller bearings are as follows:

1. The side clearance of cylindrical and elliptical bearing bushes can be adjusted by manual grinding and scraping or by adding pads and turning the bearing in the middle of the bearing.

2. For the top clearance of cylindrical and elliptical bearing bushes, manual grinding and scraping can be used or the method of adding pads to the middle face of the bearing when the situation permits.

3. For the fixed bearing bush with multiple oil wedges, in principle, it is not allowed to repair and adjust the bearing bush clearance. If the clearance is not suitable, the new pad should be replaced.

4. For multi-oil wedge tiltable bearing pads, scraping pads are not allowed to be repaired, and the pads should be replaced when the clearance is not suitable. For tiles with adjustable thickness, the number of tiles can be adjusted by adding a stainless-steel pad under the adjustment block behind the tile, or by reducing the thickness of the adjustment block. Note that for multi-oil wedge tiltable bearing pads, the thickness error between the pads in the same group should be less than 0.01mm.

Why should we pay attention to the vibration of cylindrical roller bearings during use?

In normal use, vibration is quite sensitive to the damage of cylindrical roller bearings, spalling, indentation, corrosion, cracks, wear, etc. will be reflected in the vibration measurement of cylindrical roller bearings. Therefore, by using a special bearing vibration measuring instrument (frequency analyzer, etc.), the magnitude of the vibration can be measured, and the specific situation of the abnormality can be inferred through the frequency distribution. The measured values differ depending on the operating conditions of the bearing or the installation position of the sensor. Therefore, it is necessary to analyze and compare the measured values of each machine in advance to determine the judgment standard.

Why should we pay attention to the temperature of cylindrical roller bearings during use?

A high temperature often indicates that the cylindrical roller bearing is in an abnormal condition. High temperatures are also detrimental to bearing lubricants. Sometimes the overheating of cylindrical roller bearings can be attributed to the lubricant of the bearing. If the bearing is continuously rotated for a long time at a temperature exceeding 125°C, the bearing life will be reduced. The causes of high temperature bearings include insufficient or excessive lubrication, impurities in the raceway of cylindrical roller bearings, excessively high limit speed, and long-term overload operation of bearings.
