Miniature Bearings – Four Roads to “Extension of Life”

How small are miniature bearings?

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

So where can it be applied?

It is suitable for all kinds of industrial equipment, small rotary motors and other fields with high speed and low noise, such as: office equipment, micro motors, instrumentation, laser engraving, small clocks, soft drives, pressure rotors, dental drills, hard disk motors , Stepper motors, video recorder drums, toy models, computer cooling fans, money counters, fax machines and other related fields.

The production 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 prolong the service life of miniature bearings? Xiaoyun, who has many years of experience in the production of miniature bearings, has summarized the following four main points for you

It is important to install miniature bearings correctly

Whether the installation process of the miniature bearing is correct affects the precision, life and performance of the miniature bearing. The correct installation of the bearing requires the design and assembly department to have sufficient research and rich practical experience on the installation process of the miniature bearing. And at the same time, the production operation department should install according to the operation standard.

Specific work standard items are usually as follows:

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

 

  1. Check the dimensions of the associated components and the finishing conditions of the supporting parts to see if the process requirements are loaded

 

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

 

  1. External conditions should be monitored during the use of miniature bearings, such as monitoring of temperature, vibration and noise.

 

If the above standards are carried out according to the requirements, it will help to prolong the service life of the miniature bearing. Regular security inspection will help to find potential problems early, prevent unexpected phenomena of the machine, allow the production plan to be realized, and improve the productivity and efficiency of the factory.

 

Micro bearing cleaning method

The surface of the miniature bearing will be coated with anti-rust oil. We must carefully clean it with clean gasoline or kerosene when using it, 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 and vibration noise of miniature bearings is very large. But Xiaoyun reminds that the fully enclosed bearing does not need to be cleaned and refueled.

 

Miniature Bearing Grease Selection

Since the grease is made of base oil, thickener and additives, the performance of different types and different grades of greases of the same type is very different, and the allowable rotation limits are different, so be careful when choosing.

 

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

 

The performance of the grease is mainly determined by the base oil. Generally, the low viscosity base oil is suitable for low temperature and high speed; the 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 adverse effects on each other due to different additives. It is a common misconception that more grease is better when lubricating miniature bearings.

 

Relubrication of miniature bearings

Relubrication of bearings During operation, miniature bearings require correct relubrication to perfect their performance. Miniature bearing lubrication methods 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 suitable for the conditions of use and the purpose of use. If only lubrication is considered, the lubricity of oil lubrication is dominant. However, grease lubricating oil can simplify the characteristics of the structure around the bearing.
