Lubrication quality effectively prolongs the service life of tapered roller bearings

Grease is indispensable in the work of tapered roller bearings. The maintenance of any bearing is inseparable from grease. Someone asked, is it better to have more grease? The answer is of course no. Matters needing attention when using grease for bearings.

In the maintenance of tapered roller bearings, too much grease actually has many hazards. Because grease has good adhesion, wear resistance, temperature resistance, rust resistance and lubricity, it can improve high temperature oxidation resistance, delay aging, dissolve carbon deposits, and prevent metal wear debris and oil from agglomeration. Improve the wear resistance, pressure resistance and corrosion resistance of machinery.

1. Bearing installation

Whether the tapered roller bearing is installed correctly affects the accuracy, life and performance. Therefore, the design and assembly department should fully study the bearing installation. It is hoped that the installation will be carried out according to the working standard. Items of work standards are usually as follows:

(1) Clean the bearing and bearing related parts

(2) Check the dimensions and finishing conditions of related parts

(3) Installation

(4) Inspection after the bearing is installed

(5) Supply lubricant

2. Monitoring of basic conditions of bearings

During use, the basic external conditions of tapered roller bearing operation should be monitored frequently, such as temperature, vibration and noise measurement. These regular inspections will identify potential problems early and will prevent unanticipated machine stoppages, enabling production schedules to be achieved, increasing plant productivity and efficiency.

3. Relubrication of bearings

During operation, tapered roller bearings require correct relubrication to perfect their performance. Bearing lubrication methods are divided into grease lubrication and oil lubrication. In order to make the bearing function well, first of all, it is necessary to select a lubrication method suitable for the conditions of use and the purpose of use. If only lubrication is considered, the lubricity of oil lubrication is dominant. However, grease lubrication has the advantage of simplifying the structure around the bearing.

4. Bearing unloading

When the tapered roller bearing will reach its end of life, it should be replaced.

Although tapered roller bearings can no longer be used, the correct removal of the original bearing and timely replacement of the new bearing can greatly promote the extension of the service life of the new bearing.
