How To Maintain Skf Bearing Correctly

Maintain Skf Bearing Correctly

1. Cleaning

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

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

b. During rough cleaning, use a brush to remove grease or Correctly adhesion 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 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 Correctly 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.

How To Maintain Skf Bearing Correctly

2. Inspection and judgment

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

The inspection results can be judged by those who are used to SKF bearings or proficient in SKF bearings.

The judgment criteria vary according to mechanical Correctly properties, importance and inspection cycle. In case of the following damage, SKF Bearing shall not be reused and must be replaced.

1) Fracture and defect of SKF Bearing parts.

2) Stripping of the rolling surface of the raceway surface.

Inspection method for deterioration of fag bearing grease

Fatigue Life, Noise Life And Lubrication Life Of Koyo Bearing

In the process of using fag bearings, grease is very critical. If deteriorated grease is used, it will not only fail to play its due role, but also damage fag bearings.

① Oil flow observation method

Take two measuring cups, one Correctly containing the lubricating oil to be checked and the other empty on the table. Lift the measuring cup filled with lubricating oil 30-40 cm away from the table and tilt it, let the lubricating oil flow slowly into the empty cup, and observe its flow.

The lubricating oil with good quality should flow slender, Correctly uniform and continuous. If the oil flow is fast and slow, sometimes large pieces flow down, The lubricating oil has deteriorated.

② Hand twisting

Twist the lubricating oil between the thumb and index finger and grind it repeatedly. The better lubricating oil hand feels lubricity, less wear debris and no friction.

If it feels a large friction feeling such as sand particles between the fingers, it indicates that there are many impurities in the lubricating oil and it can not be used again. It should be replaced with a new lubricating oil.

③ Illumination method

On sunny days, lift up the lubricating oil with a screwdriver at an angle of 45 degrees to the horizontal plane. Observe the condition of oil drops according to the sunlight. In the light, it can be clearly seen that there is no wear debris in the lubricating oil. It can continue to function. If there are too many wear debris, replace the lubricating oil.

④ Oil drop trace method

Take a clean white test paper and drop several drops of oil on the test paper. After the lubricating oil leaks, if there is black powder on the surface and there is a sense of astringency by hand, it indicates that there are many impurities in the lubricating oil. Good lubricating oil has no powder, and it is dry and smooth by hand with yellow marks.
