Miniature bearing is a kind of the deep groove ball bearing, miniature bearing which we usually refer to is the single row miniature deep groove ball bearing whose inside diameter is within 10 mm. The miniature bearing is suitable for all kinds of industrial equipment, small rotary motor and such high-speed low voice fields. For example,  machine, micro motor, instrument, laser engraving, small clocks, soft, pressure rotor, dental drill, hard dish drive motor, stepping motor, VCR magnetic drum, the toy model, computer cooling fan, paper, fax machine and other related areas. How to extend the service life of miniature bearing? Lily bearing collects the following four points for you.

The right installation of miniature bearing is very important.

Whether the installation of miniature bearing is correct, affects the precision, life and performance. Therefore, the design and assembly department need sufficient researches for miniature bearing installation. They should be installed in accordance with the work standards. The items of working standard are usually as followed:

Cleaning bearing and its related parts, checking the size and finishing situation of its related components, examining bearing supply lubricant after installation, monitoring bearing basic condition during the period of using, we should often examine the basic external conditions of miniature bearing operation monitoring, such as temperature, vibration and noise measurement, etc. These regular checks will find potential problems and will prevent the unexpected machine stop, make the production plan achieved, and improve plant productivity and efficiency.

Cleaning methods of miniature bearing

The surface of miniature bearing is coated with anti-rust oil, you must use cleaning gasoline or kerosene to clean carefully, then coat the clean and high quality or high speed high temperature lubricating grease, thus you can install and use. The degree of cleanliness is important for the life and vibration noise of miniature bearing. But what Lily-bearing especially votes to you is the fully closed bearing does not need cleaning and refueling. How to choose the lubrication to lubricate has a very important influence for bearing operation and life.

The selection of lubricating grease for miniature bearing

Because the grease is made of base oil, thickener and additive, the performance of different kind grease and same kind but different mark grease is vary widely, the allowed limit of rotation is different, so you need to be careful when choose. Now Lily-bearing briefly introduces general principles to select the grease.

The performance of grease is mainly decided by base oil. In generally, the low viscosity base oil is suitable for low temperature and low speed; the high viscosity is suitable for high temperature and high loading. The thickening agent is also related to the performance of lubrication; the resistance to water of thickening agent decides the grease’s water resistance. In principle, different brands of grease cannot fixed, and even the same thickening agents of grease also bring the bad influence to each other because of different additive. While lubricating the miniature bearing, it is a common wrong concept that the more lubrication coated, the better.

Re lubrication of miniature bearing

The re lubrication of miniature bearing is in the process of operation, miniature bearing requests the right re lubrication to perfect its performance. The methods of miniature bearing divided into grease lubrication and oil lubrication. In order to make most use of bearing, you should choose the suitable using condition, using purpose and lubricating method firstly. If you just consider about the lubrication, the lubricating performance of oil lubrication will take advantages. But the grease lubrication has a character to simplify the around structure of bearing.
