How To Maintain Skf Bearing

How To Maintain 

The lubrication purpose of SKF Bearing is to reduce the internal friction and wear of the bearing To Maintain and prevent burning and sticking. Its lubrication effect is as follows:

1. Reduce friction and wear

In the contact parts of the ferrule, rolling element and retainer of SKF Bearing, metal contact is prevented and friction and wear are reduced.

2. Extend fatigue life

The rolling fatigue life of SKF Bearing is prolonged when the rolling contact surface is well To Maintain lubricated during rotation. On the contrary, if the oil viscosity is low and the lubricating oil film thickness is not good, it will be shortened.

3. Discharge friction heat and cooling

Circulating oil supply method can use oil to discharge the heat To Maintain generated by friction or the heat transmitted from the outside for cooling. Prevent SKF Bearing from overheating and lubricating oil from aging.

4. Other

It also has the effect of preventing foreign matters from invading the interior of the bearing, or To Maintain preventing rust and corrosion.

How To Maintain Skf Bearing

Lubrication method: the lubrication method of SKF Bearing is divided into grease lubrication and oil lubrication.

In order to make the bearing To Maintain function well, first of all, choose the lubrication method suitable for the use conditions and purposes. If only lubrication is considered, the lubricity of oil lubrication is dominant.

However, grease lubrication has the advantage of simplifying the surrounding structure of SKF Bearing. Compare the advantages and disadvantages of grease lubrication and oil lubrication.

In order to give full play to SKF Bearing and maintain its due performance for a long time, regular maintenance (regular inspection) must be carried out. Through proper regular inspection, it is very important to find faults early and prevent accidents before they happen, which is very important to improve productivity and economy.

1. Cleaning

When the SKF Bearing is removed for inspection, the appearance record shall be made by To Maintain photography and other methods. In addition, confirm the amount of remaining lubricant and sample the lubricant before cleaning the SKF Bearing.

a. The cleaning of bearings is divided into rough cleaning and fine cleaning, and a metal grid can be placed at the bottom of the container.

b. During rough cleaning, remove grease or adhesion with a brush in the oil. At this time, if the SKF Bearing is rotated in oil, pay attention to the damage to the rolling surface due to foreign To Maintain matters.

c. During fine cleaning, rotate SKF Bearing slowly in oil and carry out it carefully.

The commonly used cleaning agent is neutral water-free diesel oil or kerosene, and sometimes warm lye is used as needed. No matter what kind of cleaning agent you use, always filter it and keep it clean. After cleaning, coat SKF Bearing with antirust oil or grease immediately.

2. Inspection and judgment

In order to judge whether the removed SKF Bearing can be reused, its dimensional accuracy, rotation accuracy, internal clearance, mating surface, raceway surface, cage and sealing ring should be emphatically checked.

The inspection results can be To Maintain judged by those who are used to SKF bearings or proficient in SKF bearings. The judgment criteria vary according to mechanical properties, importance and inspection cycle. In case of the following damage, SKF Bearing shall not be reused and must be replaced.

a. Fracture and defect of bearing parts.

b. Stripping of the rolling surface of the raceway surface.

In order to maintain the original performance of fag bearing in good condition for as long as possible, it is necessary to maintain and repair in order to prevent accidents, ensure the reliability of operation and improve productivity and economy.

Maintain the operation standard of corresponding mechanical operation conditions and carry out it regularly. The contents include monitoring the operation status, replenishing or changing the lubricant, and regular disassembly inspection. As maintenance items in operation, there are bearing rotation sound, vibration, temperature, lubricant state, etc.

Cleaning of fag bearing: when removing the fag bearing for maintenance, first record the appearance of the bearing, confirm the residual amount of lubricant, and wash the bearing after sampling the lubricant for inspection. As a cleaning agent, gasoline and kerosene are commonly used.

The cleaning of the removed fag bearing is divided into coarse cleaning and fine cleaning, which are placed in the container respectively. First, put the metal mesh bottom so that the fag bearing does not directly contact the dirt of the container. During rough cleaning, if the bearing rotates with dirt,

it will damage the rolling surface of the bearing, which should be paid attention to. In the coarse cleaning oil, use a brush to remove the grease and adhesion. After it is roughly clean, turn to fine cleaning. Fine cleaning is to carefully clean the bearing while rotating in the cleaning oil. In addition, the cleaning oil should always be kept clean.
