Detailed Steps For Maintenance Of Timken Imported Bearings

Timken Imported Bearings

In order to give full play to Timken imported bearings and maintain their 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 removing the Timken Timken Imported Bearings imported bearing for inspection, first make appearance records by photography and other methods. In addition, confirm the amount of remaining lubricant and sample the lubricant before cleaning the 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, use a brush to remove grease or adhesion in the oil. At this time, if the bearing is rotated in oil, pay attention to the damage to the Timken Imported Bearings rolling surface due to foreign matters.

c. During fine cleaning, rotate the 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, apply antirust oil or antirust grease on the bearing immediately.

2. Inspection and judgment

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

Detailed Steps For Maintenance Of Timken Imported Bearings

The inspection results can be judged by those who use inertial bearings or are proficient in bearings.

The judgment criteria vary according to mechanical Timken Imported Bearings properties, importance and inspection cycle. In case of the following damage, the bearing shall not be reused and must be replaced.

1) Fracture and defect of bearing parts.

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

Fault identification method of bearing

Without disassembly and inspection, it is very important to identify or predict whether the bearing is faulty in operation, Timken Imported Bearings which is very important to improve productivity and economy.

The main identification methods are as follows:

1) Recognition by sound

Recognition by sound requires a wealth of experience. Must be fully trained to recognize bearing sounds and non Timken imported bearing sounds. Therefore, special personnel should be assigned to carry out this work as far as possible. The sound of the bearing can be clearly heard by sticking the listener or listening stick to the shell.

2) Identification by operating temperature

This method is a comparative identification method, which is only used in the situation where the running state does not change much. For this purpose, continuous temperature recording must be carried out. In case of failure, not only the temperature rises, but also irregular changes occur.

3) Identification by lubricant status

The lubricant shall be sampled and analyzed to judge whether its turbidity is mixed with foreign matters or metal powder. This Timken Imported Bearings method is particularly effective for bearings that cannot be close to Timken’s import or large bearings.

Simple troubleshooting skills for abnormal vibration temperature of ntn bearing

How To Install Timken Self-Aligning Ball Bearing To Achieve The Longest Service Life

In the process of using ntien bearings, customers often report that the temperature will be abnormal when the bearings vibrate. According to the technical explanation of the bearing group, the factors leading to this are as follows: generally, the temperature of the bearing rises with the increase of the speed of the bearing.

The temperature is stable after stable operation for 1-2 hours. There are many main determinants of bearing temperature, such as speed, lubricating oil, load, foreign matter intrusion and so on. If the above conditions are found, the operation must be stopped and necessary inspection measures shall be taken.

It is recommended that customers use thermal sensors to monitor the working temperature of ntien bearings at any time. If the temperature of the bearing Timken Imported Bearings exceeds 125 ℃ for a long time, the service life of the bearing will be reduced.

The causes of bearing high temperature include insufficient or excessive lubrication and lubricant. It contains impurities, excessive load, damaged ring of K bearing, insufficient clearance, etc. If it is not found and handled in time, the bearing will be scrapped.

Therefore, it is necessary to Timken Imported Bearings continuously monitor the bearing temperature, whether it is measuring the bearing itself or other important parts. The temperature can be changed under any operating condition.

If the bearing produces abnormal vibration during operation, it is very easy to damage it. Specifically, it includes peeling damage, indentation damage, crack damage, abnormal wear and other damage phenomena. Therefore, the magnitude of vibration can be measured through the bearing vibration meter.

The measured value varies according to the service conditions of enten bearing or the installation position of sensor. We suggest that the customer record the value during normal operation of the machine in advance for comparative analysis.

One: observation method

If the bearing is well lubricated and properly blocks sundries and moisture, it means that the oil seal should not be worn However, when opening the bearing housing, Timken Imported Bearings visually inspect the bearing and regularly inspect the oil seal

Check the condition of the oil seals near the bearing to ensure that they are sufficient to prevent hot or corrosive liquid or gas from penetrating the bearing along the axis The protective ring and labyrinth oil seal should be coated with grease to ensure their great protection If the oil seal is worn, replace it as soon as possible.

Second: Listening

Using hearing to identify whether the ntien bearing operates correctly is a method used. If the bearing is in good working condition, it will make a low whine sound Sharp hiss, squeaks and other irregular sounds usually indicate that the bearing is in poor operation.
