Four ways  of "life extension" for  Miniature bearings

How small are miniature bearings?

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

 

what ways can it be used?

Miniature bearings are suitable for all kinds of industrial equipment, small rotary motors and other high-speed and low-noise fields, such as: office equipment, micro motors, instrumentation, laser engraving, small clocks, soft drives, pressure rotors, dental drills, hard disk motors, stepper motors, video recorder magnetic drums, toy models, computer cooling fans, money 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? As a small cloud with many years of experience in the production of miniature bearings, we have summarized the following four key points for you

 

It is important to install the miniature bearings correctly

Whether the installation process of the miniature bearing is correct affects the accuracy, life and performance of the miniature bearing. 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. At the same time, the production department must install it in accordance with the work standards.

 

The specific items of the standard of operation are usually as follows:

1. Cleaning, the bearing and bearing-related components must be carefully cleaned before bearing installation

 

2. Check whether the size of the related parts and the finishing of the supporting parts are subject to the process requirements

 

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

 

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

 

If these standards are carried out according to the requirements, it is conducive to the extension of the service life of the miniature bearings, the regular security inspection is conducive to the early detection of potential problems, the prevention of unexpected phenomena in the machine, the realization of the production plan, and the improvement of plant productivity and efficiency.

 

Miniature bearing cleaning method

The surface of the miniature bearing will be coated with anti-rust oil, and we must carefully clean it with clean gasoline or kerosene when using, 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 the impact of cleanliness on the life of miniature bearings and vibration and noise is very significant.

 

Miniature bearing grease selection

Since grease is made of base oil, thickener and additives, the performance of different types and different grades of the same type of grease varies greatly, and the permissible rotation limit is different, so it is important to pay attention when choosing.

 

The general principles of choosing grease:

 

The performance of a grease is mainly determined by the base oil. Generally, low-viscosity base oils are suitable for low temperature and high speed; High viscosity is suitable for high temperatures and high loads. The thickener is also related to the lubricating performance, and the water resistance of the thickener determines the water resistance of the grease. As a general rule, greases of different brands cannot be mixed, and even greases with the same thickener can have a negative effect on each other due to different additives. When lubricating miniature bearings, the more grease you apply, the better, is a common misconception.

 

Relubrication of miniature bearings

Relubrication of bearingsDuring operation, miniature bearings require correct relubrication to perfect their performance. The methods of lubrication of miniature bearings are 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 that is suitable for the conditions and purpose of use. If only lubrication is considered, the lubricity of oil lubrication prevails. However, grease lubricants can simplify the features of the structure around the bearing.
