Daily maintenance of bearings

Bearings are an important part of machinery. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. Maintenance work is the top priority for bearings to work properly, maintain performance, and extend life. Everyone should take it seriously.

Next, let's take a closer look at the daily maintenance work of the bearings.

First, keep the bearings lubricated and clean

Before inspecting the bearing, clean the surface of the bearing first and then remove the parts around the bearing. Pay special attention to the oil seal, which is a very fragile part. Please be careful when inspecting and disassembling the bearing to avoid damage to the part. If you have been experiencing bad symptoms when inspecting the oil seal of bearing and its surrounding parts, be sure to replace it to avoid damage to the bearing caused by a bad oil seal.

Second, to ensure the quality of bearing lubricants

The quality of the lubricant has a direct impact on bearing service life. The inspection method for the bearing lubricant is as follows: the lubricant is rubbed between the two fingers, and if there is a contaminant, it can be felt; or a thin layer of lubricant is applied on the back of the hand, and then the sealing is checked. Then it is to replace the lubricant of the bearing.

Third, the working environment of the bearing

When inspecting bearings, never expose them to contaminants or moisture. If the work is interrupted, cover the machine with a piece of oil-paper plastic or similar material. The working environment of the bearing is also very important. 

Fourth, the bearing seal

The purpose of bearing sealing is to prevent dust, moisture and impurities from entering the bearing, but also to prevent the loss of lubricant. A good seal ensures that the machine works properly, reduces noise and extends the life of the parts.

The above is the relevant introduction of the daily maintenance work of the bearing. It is mainly explained from four aspects. In fact, these four aspects are also related to each other. Therefore, bearing maintenance work is carried out closely around the four words of clean, lubrication, sealing and environment.
