Usage of CC type double row self-aligning roller bearings

The usage method of CC type double row self-aligning roller bearings mainly includes installation, usage precautions, and maintenance. The following is a detailed explanation of these aspects:

1、 Installation method

The installation of CC type double row self-aligning roller bearings requires following certain steps and precautions to ensure that the bearings can be correctly and stably installed on the equipment. The specific installation method is as follows:

preparation:

Ensure that the dimensional tolerances of bearings, shafts, and bearing chambers comply with regulations to ensure that the bearings can rotate easily without conduction obstruction.

Clean the surface of the shaft to ensure that there are no oil stains, impurities, etc.

Installation steps:

For cylindrical bore bearings, methods such as heating oil tanks, ovens, tempering furnaces, or inductive heating can be used to heat the bearings to 80-100 ℃, and then quickly fit the bearings onto the shaft. When heating, it is important to note that the oil temperature should not exceed 120 ℃, and the heating insulation time depends on the size of the bearing.

For tapered bore bearings, installation can be carried out using a tightening sleeve or a retraction sleeve. During installation, it is important to ensure that the tightening sleeve or retraction sleeve is correctly installed on the shaft. Then, place the bearing sleeve onto the tightening sleeve or retraction sleeve and secure it with a locking nut or hydraulic nut.

Clearance adjustment:

After installation, it is necessary to adjust the clearance. The adjustment of clearance should be based on the inner diameter size of the bearing and the recommended residual clearance to ensure that the bearing can maintain good operating condition during operation.

2、 Precautions for use

Avoid overloading:

During use, overloading of bearings should be avoided to prevent bearing damage.

Control speed:

The speed of the bearing should be controlled within the specified range to avoid adverse effects on the bearing caused by excessively high or low speeds.

Lubrication and dust prevention:

Bearings should be lubricated regularly to reduce friction and wear. Meanwhile, it is necessary to cover the bearings with plastic film to prevent dust and prevent impurities from entering the interior of the bearings.

Preventing paint rust:

For sealed electric motors and other equipment, good three proof coatings should be selected during installation, and natural ventilation should be carried out after a certain period of air drying after installation to prevent the formation of paint rust.

3、 Maintenance

Regular inspection:

Regularly inspect bearings, including their operating status, temperature, vibration, and noise, in order to promptly identify and address potential issues.

Cleaning and replacement:

If impurities or severe wear are found inside the bearing, it should be cleaned or replaced in a timely manner. When cleaning, it is important to use appropriate cleaning solution and tools to avoid damaging the bearings.

Storage:

If bearings need to be stored for a long time, they should be placed in a dry, ventilated, non corrosive environment and regularly maintained and serviced.

In summary, the use of CC type double row self-aligning roller bearings involves multiple aspects such as installation, usage precautions, and maintenance. During use, it is necessary to strictly follow relevant regulations and precautions to ensure that the bearings can operate stably for a long time.
