The important role of SKF non-standard bearing lubrication in the elimination of the guide

In general, non-standard bearings heat up after they start running, and after a period of time, they are at a lower temperature (usually 10 to 40 degrees higher than room temperature). The normal time is different depending on the size, form, rotation speed, lubrication method of the SKF bearing, and the exothermic conditions around the non-standard bearing. It takes about 20 minutes to several hours.

When the temperature of the non-standard bearing does not reach the normal state and the abnormal temperature rises, the following reasons may be considered. In addition, the machine should be stopped as soon as possible and necessary countermeasures should be taken. Temperature is essential for maintaining the proper life of non-standard bearings and preventing deterioration of lubricating oil. It is recommended to use as much as possible under non-high temperature conditions (generally below 100 degrees). The main cause of abnormal temperature rise is too much or too little. Poor installation of SKF bearings. The internal clearance of non-standard bearings is too small, or the load is too large. The friction of the seal is too large. The lubricant does not match. The creep of the mating surface.

1. Firstly, the parts of the SKF bearing are lubricated to reduce the friction and wear of the bearing;

2. The rolling contact surface of the bearing often forms an appropriate oil film to prolong the fatigue life of the non-standard bearing;

3. The heat generated by friction or other reasons inside the bearing is removed by lubrication;

4. Through lubrication, it can achieve anti-rust and dust-proof effects on non-standard bearings.

Therefore, we must correctly understand the importance of lubrication for SKF bearings, improve bearing performance and reduce consumption.https://www.supplyforever.com/

Extend the life cycle of TIMKEN angular contact ball bearings from maintenance

The main task of angular contact ball bearing failure analysis is to find out the main factors causing bearing failure based on a large number of background materials, analysis data and failure modes, so as to propose improvement measures in a targeted manner, extend the service life of bearings, and avoid TIMKEN bearings. A sudden early failure occurred.

First of all, the structural design is reasonable and advanced, so that there will be a long angular contact ball bearing life. Bearings are generally manufactured through multiple processes such as forging, heat treatment, turning, grinding and assembly. The rationality, advancement and stability of each processing technology will also affect the life of the bearing. The heat treatment and grinding processes that affect the quality of the finished TIMKEN bearing often have a more direct relationship with the failure of the bearing. In recent years, research on the metamorphic layer of bearing working surface shows that the grinding process is closely related to the bearing surface quality.

1, pay attention to the installation of the bearing

Whether the bearing is installed correctly affects accuracy, life and performance. Therefore, the design and assembly department should fully study the installation of bearing products. I hope to install according to the operating standards. The items of the job standard are usually as follows:

(1) cleaning the bearing and bearing related components;

(2) Check the size and finishing of the connected components;

(3) installation;

(4) Inspection after installing the bearing;

(5) Supply lubricant. Carefully do the five steps of bearing installation

2, alignment, straightening

After the TIMKEN bearing is installed, alignment may result in additional loads, friction and vibration of the bearing if not carefully aligned. These can accelerate fatigue and reduce the service life of bearing products and can damage the life of other machine parts. In addition, increased vibration and friction can greatly increase energy consumption and risk of premature failure.

3. Basic condition monitoring

During use, the basic external conditions of the bearing operation are often monitored, such as temperature, vibration and noise measurements. Bearing experts point out that these regular inspections will identify potential problems early and will prevent unexpected machine stops, enabling production plans, increased plant productivity and efficiency.https://www.supplyforever.com/
