Usage of CA Copper Insulated Spherical Roller Bearings

CA copper insulated self-aligning roller bearings, also known as CA type self-aligning roller bearings, mainly involve installation, lubrication, testing, and maintenance. The following is a detailed explanation of its usage method:

1、 Installation

preparation

Clean the surface of bearings and shafts to ensure that there are no impurities such as oil stains or dust.

Check the accuracy of the shaft and the fit of the bearing seat to ensure compliance with installation requirements.

Installation method

Heating installation: Heat the bearing to 80 ℃~100 ℃, and then quickly fit it onto the shaft. Heating methods can include heating oil tanks, bearing heaters, ovens, or tempering furnaces. During the heating process, attention should be paid to controlling the oil temperature to avoid bearing overheating.

Hydraulic nut installation: For tapered bore bearings, hydraulic nuts can be used for installation. Install the bearing on the shaft and press it into place using hydraulic nuts. During the installation process, attention should be paid to measuring the radial clearance of the bearing to ensure that it meets the installation requirements.

Installation precautions

During installation, excessive impact force should be avoided on the shaft to prevent damage to the bearings.

After installation, it is necessary to check whether the bearing rotates flexibly and whether there is any jamming phenomenon.

2、 Lubrication

Lubrication method

The lubrication method for self-aligning roller bearings is usually oil lubrication or grease lubrication.

For bearings operating at high speeds, oil lubrication should be used to ensure good heat dissipation and lubrication effects.

Selection of lubricants

Suitable lubricants should be selected based on factors such as the working conditions, speed, and load of the bearings.

Lubricants should have good oxidation resistance, rust prevention, and extreme pressure and wear resistance.

Lubricant addition

When installing bearings, an appropriate amount of lubricant should be applied inside the bearings.

During use, the amount and quality of lubricant should be regularly checked, and timely replenishment or replacement should be carried out.

3、 Testing and maintenance

Measurement of radial clearance

Measure the radial clearance of the bearing using tools such as a feeler gauge to ensure it is within the specified range.

When measuring, attention should be paid to keeping the bearing and measuring tool isothermal to avoid measurement errors.

Cleaning of bearings

Regularly clean the bearings to remove surface oil stains and impurities.

When cleaning, specialized cleaning agents should be used to avoid using highly corrosive solutions.

Maintenance of bearings

Regularly check the operation of the bearings, and if there are any abnormal sounds, vibrations, or other phenomena, stop the machine for inspection in a timely manner.

For bearings that operate for a long time, lubricants should be replaced regularly to maintain good lubrication of the bearings.

If damage or wear is found on the bearings, they should be replaced with new bearings in a timely manner.

In summary, the use of CA copper insulated self-aligning roller bearings involves multiple aspects such as installation, lubrication, testing, and maintenance. During use, strict operation and maintenance should be carried out in accordance with regulations to ensure the normal operation of bearings and extend their service life.
