Renew Bearing of Hatch Cover Rollers in Ha Long anchorage

Renew Bearing of Hatch Cover Rollers

In the maritime industry, the maintenance and replacement of critical ship components are essential to ensure safety and operational efficiency. One such crucial task is renewing the bearings of hatch cover rollers. Below is a detailed procedure for this renewal task.

1. Initial Assessment

After conducting an inspection, we discovered that the bearing had been previously removed by the ship’s crew and temporarily repaired. However, there was no bearing inside, which led to the shaft wearing out after a period of operation and becoming unusable.

2. Shaft Evaluation

Upon further evaluation, we found that the shaft needed to be replaced. The crew’s temporary repair was not done correctly, making it difficult for the repair team to remove the shaft. We had to use a gas cutting torch to remove the old shaft.

3. Coaxiality Measurement

During the shaft replacement process, coaxiality measurements should be performed to ensure the new shaft is installed correctly and without any misalignment.
