How to make bearings easy to use and durable?

To make bearings easy to use and durable, we need to start from many aspects, including selecting suitable bearings, correct installation and disassembly, proper lubrication and maintenance, and reasonable usage conditions. Here are some specific measures and suggestions:

1. Choose suitable bearings

Clarify the conditions of use:

Analyze the function and structure of the mechanical device, the location where the bearing is used, load (size, direction), rotation speed, vibration and impact, bearing temperature (surrounding temperature, temperature rise), and surrounding atmosphere (corrosiveness, cleanliness, lubricity) and other conditions .

Select the appropriate bearing type according to the use conditions, such as deep groove ball bearings, angular contact ball bearings, cylindrical roller bearings, tapered roller bearings, etc., to meet different load capacity and rotation accuracy requirements.

Selected bearing configuration:

Usually, the shaft is supported by two bearings in the radial and axial directions. One side is a fixed side bearing, which bears radial and axial loads, and the other side is a free side bearing, which only bears radial loads and can bear axial loads. move.

Choose the appropriate bearing configuration, such as the structural selection of fixed-end and free-end bearings, to ensure shaft stability and bearing life.

2. Correct installation and disassembly

Choose the appropriate installation tool:

Use appropriate tools such as wrenches, screwdrivers, pliers, etc. to increase installation efficiency and avoid damaging the bearings.

Pay attention to the installation order:

Generally speaking, the outer ring is installed first, then the inner ring, and finally the cage. Make sure the installation sequence is correct to avoid bearing wear or damage.

Cleaning and inspection:

Before installation, clean the bearing surface and check for impurities or damage.

When installing, ensure that the fit between the bearing and the shaft or bearing seat is appropriate and avoid being too tight or too loose.

Follow manufacturer's instructions:

Follow the manufacturer's installation and removal instructions to ensure correct operation.

3. Proper lubrication and maintenance

Choose the right lubricant:

Choose the appropriate lubricant, such as oil or grease, based on the bearing type and working environment.

For high-precision, high-speed bearings, it is recommended to use special grease or add lubricating oil.

Change lubricant regularly:

Check the lubrication effect regularly and replace the lubricant according to usage time and mileage.

Avoid using too much or too little lubricant to avoid overheating or insufficient lubrication of the bearings.

Regular cleaning and inspection:

Clean the bearings and the surrounding area regularly to ensure there is no residue or debris.

Check the appearance, wear degree, rotation flexibility, etc. of the bearing to find and deal with problems in time.

4. Reasonable conditions of use

Control load:

Make sure the equipment operates within the rated load range to avoid overloading.

If equipment loads change, the bearings should be adjusted to accommodate these changes.

Control temperature:

Check the bearing temperature regularly to ensure it is within the normal range.

For high-temperature environments or heavy-duty applications, consider using special materials and mounting methods to reduce temperatures.

Protect against shock and vibration:

Avoid exposing bearings to shock or vibration to prevent bearing damage or loosening.

For applications that are susceptible to shock, consider using buffer bearings or other shock-resistant designs.

5. Regular maintenance and replacement

Preventive maintenance:

Perform preventive maintenance on bearing types prone to failure.

Regularly replace bearing parts that are prone to wear, such as balls or cages.

Timely replacement:

If the bearing is seriously damaged or cannot meet the usage requirements, it should be replaced with a new bearing in time.

When replacing, choose the appropriate model and grade, and follow the correct method for replacement.

By selecting suitable bearings, correct installation and disassembly, proper lubrication and maintenance, and reasonable use conditions, bearings can be made more useful and durable.
