How small are Miniature Bearings?

It refers to single row Deep Groove Ball Bearing with inner diameter less than 10mm.

So in what aspects can it be applied?

Miniature Bearings are suitable for various industrial equipment, small rotary motors, and other high speed and low noise fields, such as office equipment, micro motors, instrument instruments, laser engraving, small clocks, soft drives, pressure rotors, dental drills, hard disk motors, stepper motors, magnetic drums for video recorders, 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 long-term replacement of Miniature Bearings is relatively high. So how to extend the service life of Miniature Bearings? Xiao Yun, who has years of experience in the production of Miniature Bearings, has summarized the following four key points for you.

It is important to install Miniature Bearings correctly

The correct installation process of Miniature Bearings affects their accuracy, lifespan, performance, and other aspects. 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 and operation departments should install according to the operating standards.

The specific operation standard items are usually as follows:

1. Before installing the bearing, it is necessary to carefully clean the bearing and its associated components

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

3. After installation, it is necessary to check the bearing lubricant and whether 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 these standards are all carried out according to requirements, it is beneficial to extend the service life of Miniature Bearings. Regular security checks are beneficial for early detection of potential problems, preventing unexpected phenomena in the machine, enabling production plans to be realized, and improving factory productivity and efficiency.

Cleaning method for Miniature Bearings

The surface of Miniature 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 so is simple, as cleanliness has a significant impact on the lifespan and vibration noise of Miniature Bearings. But Xiaoyun reminds me that fully enclosed bearings do not require cleaning or refueling.

Selection of lubricating grease for Miniature Bearings

Due to the fact that lubricating greases are made from base oil, thickeners, and additives, the performance of different types and brands of lubricating greases of the same type varies greatly, and the allowable rotation limit varies. Therefore, it is important to pay attention when selecting them.

But here, JJJ BEARING will briefly introduce to you the general principles for selecting lubricating grease:

The performance of lubricating grease is mainly determined by the base oil. Low viscosity base oils are generally suitable for low temperatures and high speeds; High viscosity is suitable for high temperatures and loads. Thickener also affects lubrication performance, and the water resistance of thickener determines the water resistance of lubricating grease. In principle, lubricating greases of different brands cannot be mixed, and even lubricating greases with the same thickener can have negative effects on each other due to different additives. When lubricating Miniature Bearings, the more grease you apply, the better, which is a common misconception.

Relubrication of Miniature Bearings

The relubrication of bearings requires correct re lubrication during operation to perfect its performance. The lubrication methods for Miniature Bearings are divided into grease lubrication and oil lubrication. In order to make the bearings function well, first of all, it is necessary to choose a lubrication method that is suitable for the conditions and purpose of use. If only lubrication is considered, the lubricity of oil lubrication is advantageous. However, grease lubricating oil can simplify the advantages of the surrounding structure of bearings.
