Micro bearings - the four main roads of "prolonging life"

How small is a miniature bearing?

It refers to a single row deep groove ball bearing with an inner diameter of less than 10 millimeters.

In what areas can it be applied?

Micro bearings are suitable for various industrial equipment, small rotary motors and other high-speed and low-noise fields, such as office equipment, micro motors, instruments, laser engraving, small clocks, soft drives, pressure rotors, dental drills, hard disk motors, stepper motors, camera drums, toy models, computer cooling fans, cash counting machines, fax machines and other related fields.

The manufacturing process of miniature bearings is more precise than ordinary bearings, and the cost of long-term replacement of miniature bearings is relatively high. So how to extend the service life of miniature bearings?

Proper installation of miniature bearings is crucial

Whether the installation process of micro bearings is correct affects the accuracy, service life, performance, and other aspects of micro 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 micro bearings. And at the same time, the production operation department must install according to the operation standards.

The specific homework standard items are usually as follows:

1. Cleaning requires careful cleaning of the bearings and their associated components before installation;

2. Check whether the dimensions of related components and the precision machining of supporting parts meet the process requirements;

3. After installation, it is necessary to check whether the bearing lubricant and the basic operating conditions of the bearing are normal;

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

If the above standards are all carried out according to requirements, it is beneficial to extend the service life of micro bearings, and regular safety checks are conducive to early detection of potential problems, preventing unexpected phenomena in machines, enabling production plans to be realized, and improving factory productivity and efficiency.

Cleaning methods for miniature bearings

The surface of micro bearings will be coated with anti rust oil. When using them, we must carefully clean them with clean gasoline or kerosene, and then apply clean high-quality or high-speed high-temperature lubricating grease before installation and use. The reason for doing this is simple, because cleanliness has a significant impact on the lifespan and vibration noise of micro bearings. However, it should be noted that fully enclosed bearings do not require cleaning or oiling.

Selection of lubricating grease for micro bearings

Due to the fact that lubricating grease is made from base oil, thickeners, and additives, the performance of different types and grades of lubricating grease varies greatly, and the allowable rotation limits are also different. Therefore, it is important to pay attention to this when selecting.
