Give full play to the bearing and long-term to maintain its proper performance, periodic maintenance (periodic inspection must be a really good job).

Through appropriate periodic inspection, so that early detection of failure, to prevent accidents in the first place, is very important to improve the productivity and economy.

1, cleaning

Good appearance record bearing removed for inspection, first with photography and other methods. In addition, to confirm the remaining amount of lubricant and lubricant sampling, and then cleaning the bearings.

a bearing rough cleaning and fine cleaning sub-washing can be placed in the bottom of the container used in the metal grid.

b, coarse wash oil used brushes to clear grease or sticky materials. At this time if rotating bearings in the oil, pay attention because the foreign body and damage the raceway.

c, sperm washing, the oil in slowly rotating bearings should be carefully carried out.

Cleaning agents commonly used for the neutral does not contain water, diesel or kerosene, sometimes warm lye. No matter what kind of cleaning agent must often filter kept clean.

After cleaning, immediately coated anti-rust oil or antirust grease on the bearing.

2, inspection and judgment

In order to judge to remove the bearing can re-use, we should focus on to check the dimensional accuracy, precision of rotation, internal clearance, as well as with the surface, raceway, cage and ring.

The test results can be use used to bearing or proficient in the bearings to be judged.

The judgment criteria vary according to the mechanical properties and importance, as well as inspection cycle. If the damage, the bearings must not be reused and must be replaced.

1) fracture of the bearing parts and defects.

2) roll the peel of the rolling surface of the pavement material.

Bearing fault identification method

By removing the check, whether the failure to identify or predict operation in bearing, is very important to improve productivity and economy.

The identification method is as follows:

1) be identified by voice

A wealth of experience through the voice recognition needs. Must undergo adequate training to be able to identify the bearing sound and non-bearing sound. To this end, the person should try to carry out this work. Listening or listening stick attached to the shell can clearly hear the voice of the bearing.

2) to identify the operating temperature

The method is comparative identification method is limited to use less change in the operation of state occasions. Therefore, we must carry out a continuous record of temperature. Fails, not only temperature, but also irregular changes.

3) identify the status of the lubricant

Lubricant sampling and analysis, to judge by its pollution level is mixed with foreign matter, or metal powders. The method of observation can not be close to the bearing or large bearing is particularly effective.
