The application fields of UC200 series outer spherical bearings mainly include:

1. Agriculture: UC200 series outer spherical bearings are widely used in various agricultural machinery, such as tractors, harvesters, straw returners, threshers, etc.

2. Industrial machinery: UC200 series outer spherical bearings are also widely used in the field of industrial machinery, such as textile machinery, ceramic machinery, etc.

3. Other fields: In addition to agricultural and industrial machinery, UC200 series outer spherical bearings can also be used in various occasions that need to bear radial and axial combined loads, such as automobiles, aerospace, transportation, electricity, electric, refrigeration and various rotating industrial fields and various transmission devices.

When using UC200 series outer spherical bearings, the following points should be noted:

1. Accurate installation and positioning: Although the installation and positioning of UC200 series bearings are not as accurate as deep groove ball bearings, their positioning accuracy must still be ensured during installation to avoid poor alignment of the axis between the shaft and the seat hole or large deflection due to long shaft.

2. Axial load control: When outer spherical bearings with top screws are used for through shafts with large rigidity difference and deflection, the axial load allowed when the top screws are tightened on the shaft shall not exceed 20% of the rated dynamic load.

3. Maintain lubrication: UC200 series bearings are filled with an appropriate amount of lubricant when leaving the factory. No cleaning or lubricant needs to be added before installation. However, during operation, the lubricant inside the bearing may gradually disappear and needs to be checked and replenished regularly.

4. Prevent impurities from entering: UC200 series bearings adopt a double-layer sealing structure, but during use, dust, moisture and other impurities should be avoided as much as possible to avoid entering the bearing to avoid affecting the normal operation and life of the bearing.

5. Regular inspection: Regularly check the operating status and lubrication of the bearings. If any abnormality is found, it should be handled in time to avoid the problem from expanding and affecting the service life of the bearings.

During the application process of UC200 series outer spherical bearings, attention should be paid to accurate installation and positioning, control of axial load, maintenance of lubrication, prevention of impurities from entering, and regular inspection to ensure its normal operation and extend its service life.

The installation and precautions of UC200 series outer spherical bearings are as follows:

1. Bearing seat: Select a suitable bearing seat and ensure that its surface is clean and free of impurities to avoid damage to the bearing.

2. Lubricant: Apply an appropriate amount of lubricant to the surface of the bearing seat and bearing to play a lubricating and rust-proof role.

3. Alignment: Place the bearing seat and bearing in the correct position and ensure that the two are aligned.

4. Installation: Gently knock the bearing into the bearing seat until the bearing is fully installed in the bearing seat. Be careful not to use excessive force to avoid damaging the bearing.

5. Adjustment: Adjust the position of the bearing as needed to align it correctly with the bearing seat.

6. Fixing: Use appropriate tools to fix the bearing seat and bearing together to ensure that they will not loosen.

7. Inspection: Check whether the bearing can rotate freely after installation, and deal with any problems in time.

Precautions:

1. Avoid excessive knocking or impact during installation to avoid damaging the bearing or affecting its performance.

2. Regularly check the lubrication status and rotation flexibility of the bearing to ensure its normal operation.

3. During use, dust, moisture and other impurities should be avoided as much as possible to prevent them from entering the bearing to avoid affecting the normal operation and life of the bearing.

4. If the bearing has any abnormal conditions, such as jamming, abnormal noise, etc., it should be checked and handled in time.

The disassembly steps of UC200 series outer spherical bearings are as follows:

1. Clean the bearing seat and bearing to ensure that the surface is clean and free of impurities.

2. Use appropriate tools to loosen the parts that fix the bearing seat and bearing together, such as screws, nuts, etc.

3. Disassemble the adapter sleeve or tapered shaft head between the bearing seat and the bearing.

4. Clean the lubricant between the bearing seat and the bearing.

5. Use a soft hammer to gently tap the outer sleeve of the bearing to remove the bearing from the bearing seat.

6. Separate the outer sleeve of the bearing from the inner ring, and separate the inner ring from the outer sleeve.

It should be noted that the disassembly of the UC200 series outer spherical bearings should use appropriate tools to avoid using excessively violent or improper methods to avoid damaging the bearing or related parts. At the same time, during the disassembly process, pay attention to keeping the surface of the bearing seat and the bearing clean to prevent impurities from entering the bearing.

The difference between UC200 series and UC300 series outer spherical bearings:

1. The ability of the bearing seat to bear loads: UC300 series outer spherical bearings can bear larger loads than UC200 series coaxial diameter sizes. This means that when the bearing seat is subjected to a larger load, UC300 series bearings are more suitable for use.

2. Bearing self-aligning ability: Although both are a variant of deep groove ball bearings, and the outer diameter surface of the outer ring is a spherical surface, it plays a self-aligning role when it is matched into the corresponding concave spherical surface of the bearing seat. However, the inner diameter of the tapered outer spherical ball bearing (such as UK200 series and UK300 series) is a tapered inner hole with a ratio of 1:12, and it must be used in conjunction with a tight sleeve when used.

3. Use environment: If the application environment needs to bear a smaller load, the UC200 series is usually selected; otherwise, the UC300 series will be selected.

There are differences in the load bearing capacity, self-aligning ability and use environment between the UC200 series and UC300 series outer spherical bearings. The specific type of bearing to be selected needs to be determined according to the actual application requirements.
