Methods for repairing seated spherical bearings

Bearings are common parts in mechanical equipment. Their function is to support and rotate the shafts in mechanical equipment. Due to long-term use and wear, bearings may fail and need to be repaired. Here are some common methods for repairing bearings.

1. Replace the bearing

If the bearing is severely damaged, the best way is to replace the bearing. Before replacing the bearing, you need to disassemble the bearing, clean it, and check whether the bearing seat and the bearing seat hole are damaged. If there is damage, you need to repair or replace it. Then choose the appropriate bearing model and install it according to the correct installation method.

2. Grinding the bearing seat

If the bearing seat is not seriously damaged, you can use grinding to repair it. First, you need to disassemble the bearing seat, and then use a grinding wheel or grinder to grind the bearing seat to make its surface smooth. When grinding, be careful not to grind excessively to avoid excessive wear and loosening of the bearing.

3. Repair welding the bearing seat

If the bearing seat is severely damaged, you can use repair welding to repair it. First, you need to disassemble the bearing seat, and then use a welding machine to repair welding the bearing seat. When repairing welding, it is necessary to control the welding temperature and time to avoid deformation or cracks caused by overheating. After the repair welding is completed, the bearing seat needs to be ground with a grinding wheel or grinder to make its surface flat.

4. Replace the bearing seat

If the bearing seat is severely damaged and cannot be repaired, the bearing seat needs to be replaced. When replacing the bearing seat, it is necessary to select the appropriate model and install it according to the correct installation method. When installing, it is necessary to pay attention to the matching size of the bearing seat and the bearing seat hole to avoid loosening or over-tightening of the bearing due to improper installation.

Repairing bearings requires choosing the appropriate method according to the specific situation. Safety needs to be paid attention to during the repair process to avoid damage to personnel and equipment. At the same time, regular inspection and maintenance of bearings can extend the service life of bearings and reduce the possibility of failure.
