Extended rod end joint bearing use period maintenance and maintenance

- May 20, 2019-

After the rod end joint bearing is installed, if it is not carefully aligned, alignment may result in additional load, friction and vibration of the rod end joint bearing. These can accelerate fatigue and reduce bearing life 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.

 

In order to fully utilize the bearings and maintain their proper performance for a long time, regular maintenance (regular inspection) must be performed. Through proper periodic inspections, early detection of failures and prevention of accidents are important to improve productivity and economy.

 

Cleaning

 

When the rod end joint bearing is removed for inspection, the appearance record is first recorded by photography. Also, verify the amount of lubricant remaining and sample the lubricant before cleaning the bearings.

 

a. The cleaning of the bearing is carried out by rough washing and fine washing, and a metal mesh frame can be placed on the bottom of the used container.

 

b. When rough washing, remove the grease or adherent with a brush or the like in the oil. At this time, if the rod end joint bearing is rotated in the oil, be careful that the rolling surface will be damaged by foreign matter or the like.

 

c. When washing finely, slowly rotate the bearing in the oil and carefully.

 

The cleaning agent generally used is a neutral non-aqueous diesel oil or kerosene, and a warm alkali liquid or the like is sometimes used as needed. Regardless of which cleaning agent is used, it is often filtered and kept clean.

 

2. Inspection and judgment

 

In order to judge whether the removed rod end joint bearing can be reused, it is necessary to check its dimensional accuracy, rotation accuracy, internal clearance, mating surface, raceway surface, cage and seal ring.

 

3. Basic condition monitoring

 

During use, the basic external conditions of the operation of the US rod end bearing are often monitored, such as temperature, vibration and noise measurements. These regular inspections will identify potential problems early and will prevent unexpected machine stops, enabling production plans, increased plant productivity and efficiency.

 

4. Relubricate

 

During operation, the bearing is required to have the correct relubrication to perfect its performance. The method of bearing lubrication is divided into grease lubrication and oil lubrication. In order to make the bearing function well, first, choose a lubrication method that suits the conditions of use and the purpose of use. Lubricity of oil lubrication predominates if only lubrication is considered. However, grease lubrication has the advantage of simplifying the structure around the bearing.

 

5. Remove

 

When the bearing will reach its end of life, it should be replaced. Although the bearing can no longer be used, correctly removing the original rod end joint bearing and replacing the new bearing in time can promote the service life of the new rod end joint bearing. First, the use of a suitable removal tool will help prevent damage to other machine components. Second, improperly removed technology can be hazardous to the operator.
