How small are miniature bearings?

It refers to single row deep groove ball bearings with an inner diameter within 10 mm.

In what ways can it be applied?

Miniature bearings are suitable for high-speed and low-noise fields such as various industrial equipment and small rotary motors, such as: office equipment, micro motors, instrumentation, laser engraving, small clocks and watches, soft drives, pressure rotors, dental drills, hard disk motors , stepper motors, video recorder drums, toy models, computer cooling fans, currency counters, fax machines, and other related fields.

The manufacturing process of miniature bearings is more precise than ordinary bearings, and the cost of replacing miniature bearings for a long time is relatively high. So how to extend the service life of miniature bearings? Xiaoyun, who has many years of experience in the production of miniature bearings, summed up the following four main points for you

Correct installation of miniature bearings is important

Whether the installation process of miniature bearings is correct or not affects the accuracy, life and performance of miniature bearings. The correct installation of bearings requires the design and assembly department to have sufficient research and rich practical experience in the installation process of miniature bearings. And at the same time, the production operation department should carry out the installation according to the operation standard.

The specific work standard items are usually as follows:

1. Cleaning, the bearing and bearing-related parts must be carefully cleaned before the bearing is installed

2. Check whether the size of related parts and the finishing condition of supporting parts meet the process requirements

3. After installation, it is necessary to check whether the bearing lubricant and the bearing are basically in normal operating conditions

4. During the use of miniature bearings, external conditions should be monitored, such as: temperature, vibration and noise monitoring.

If the above standards are carried out according to the requirements, it is beneficial to extend the service life of the miniature bearings. Regular security inspections are conducive to early detection of potential problems, preventing unexpected phenomena on the machine, enabling production plans to be realized, and improving factory productivity and efficiency.

Miniature bearing cleaning method

The surface of the miniature bearing will be coated with anti-rust oil. When we use it, we must clean it carefully with clean gasoline or kerosene, and then apply clean high-quality or high-speed and high-temperature lubricating grease before installation and use. The reason for this is simple, because cleanliness has a great influence on the life and vibration and noise of miniature bearings. But Xiaoyun reminds me that fully enclosed bearings do not need to be cleaned and refueled.

Miniature Bearing Grease Selection

Since the grease is made of base oil, thickener and additives, the properties of different types and different grades of the same type of grease vary greatly, and the allowable rotation limit is different, so be sure to pay attention when choosing.

But here Xiaoyun briefly introduces to you the general principles of selecting grease:

The performance of grease is mainly determined by the base oil. Generally, low-viscosity base oil is suitable for low temperature and high speed; high-viscosity base oil is suitable for high temperature and high load. The thickener is also related to the lubricating performance, and the water resistance of the thickener determines the water resistance of the grease. In principle, greases of different brands cannot be mixed, and even greases with the same thickener will have a bad influence on each other due to different additives. It is a common misconception when lubricating miniature bearings that more grease is better.

Relubrication of miniature bearings

Bearing relubrication During operation, miniature bearings require correct relubrication to perfect their performance. The method of miniature bearing lubrication is 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. But the special feature of grease lubricating oil can simplify the structure around the bearing.
