9 important notes when using bearings, bearings

Incorrect use of bearings inadvertently reduces bearing performance directly. This causes the bearings to quickly reach the operating limit, so it will directly affect the operation of machinery parts, production lines, if heavier will be the main cause of many risks to the system. your system. Here are 9 important notes to help you use bearings effectively.

1. Select suitable grease for bearings

Lubricants act as lubricants, reducing the wear and tear caused by friction, they also have the function of efficient heat transfer and conduction. Therefore, depending on the type of bearing, which the manufacturer recommends to use the appropriate type. Lubricants for bearings by many people do not have to know what they are? This is a mistake from the very beginning. Because each grease lubricates they have a different viscosity and performance under different conditions. Therefore, to use the correct type, it is necessary to consult the manufacturer's recommendations.

Some types of bearings, bearings manufacturers have oiled, or grease and. We buy, install and use without needing to install more. There are some people who often open the lid of the bearing and add more. This is not recommended because adding it is extremely dangerous if it is not of the same type as already available. When in operation, they can react by not working together, creating a sludge that directly affects the bearing. If the grease is applied to the same type as the one available, this is not good, it will reduce the viscosity, reduce the heat transfer and thus more or less affect the performance of the bearing.

Is there a need to replace the grease in bearings? How often to replace once. Manufacturers have calculated the amount of grease available in a bearing will function for its full life without needing to be replaced. If you install and use bearings correctly according to the manufacturer's recommendations, the lubricating grease does not need to be replaced.
3. How to install bearings correctly?
Correct installation of bearings is crucial for operational stability and bearing life. Each type of bearing has different functions and sizes specified on the accompanying Catalog, usually experts assemble them very gently, never use much force or try to insert the wheel to close the bearing. Correct fitting of bearings is for people with mechanical experience, knowledgeable about your systems, and knowledgeable about each type of bearing. Therefore, if you are inexperienced in the machine system or do not have a thorough understanding of the bearing type, you should not install it, you need to consult an expert or recommend the manufacturer.

4. How to choose the appropriate bearings?

There are many types of bearings are manufactured to suit the profession of each part, of each different machine. We cannot replace the bearings installed in a high load crane installed in the motor system. Each type of bearing is specified by manufacturers about the specifications such as: size, speed, level of load ... A person who understands the bearing parameters to compare with the operating system. of its machinery part it is smart to choose the most suitable bearings. But if you are not familiar with either of the above, please consult an expert, or the manufacturer's recommendations. In addition, you should choose genuine bearings, bearings with clear origin for your machine to operate more stably.
5. Average working life of the bearing?
The main use of bearings is to reduce contact friction. More precisely, replace rolling friction operation with sliding friction. Service life for the same bearing but used for different applications will not be the same. Technically, the bearing life is determined by the number of revolutions and varies (affected) depending on: load (heavy or light, even or irregular), working temperature (high or low). , working environment (dirt, humidity, chemicals, ...).
6. How do I know when a bearing is about to fail?
The bearing failure phenomenon is the phenomenon of bearings working to the limit of the number of revolutions. Either operating too much, or being hit by an external force ... A bearing that is about to fail often has the following signs:
- The bearing assembly temperature has increased abnormally
- There is unusual noise and hissing noise.
- There is abnormally high vibration and shaking
- Or have deformed bearings
Regularly monitoring the operation, parameters, signs described above, the user can evaluate and accurately predict the operating status of the bearing. From there offer solutions to fix problems.
7. How to know the working status of the bearing while in use?
The operating status of the bearing will be reflected in the parameters of temperature, noise, vibration ... Currently, the method is considered the most effective for monitoring the operating status and making early prediction. Bearing failures are a method of measuring and analyzing bearing vibrations.
8. How to measure bearing wear?
Each type of bearing is manufactured with a certain tolerance. We understand that this error is the contact between the ball and the chutes
