How many inspections are there in Spherical Roller Bearings?

Spherical roller bearings are a kind of rolling bearings that can handle different situations. They are useful in many places, like mining, building houses, and generating power. To make them work well, we need to check them often. This essay will tell you how to check spherical roller bearings.

There are two times to check spherical roller bearings: when the machine is running and when the machine is stopped. When the machine is running, we need to look at the temperature, vibration, noise, and oil of the bearings. These things can tell us if the bearings have any problems, and what the problems are. For example, the temperature is too high because of too much friction, not enough oil, or the bearings are not straight; the vibration or noise is not normal because the parts of the bearings are broken, worn, or dirty; the quality or quantity of the oil changes and affects the lubrication and protection of the bearings.

When the machine is stopped, we need to clean and inspect the bearings. Cleaning the bearings can remove the oil and dirt, so we can check them better. We can use light oil or kerosene to clean, use metal net to support the bearings, let them spin in the oil, use a brush or something else to remove the deposits. After cleaning, we need to dry the bearings and put some oil again. Inspecting the bearings can see if the parts of the bearings have any problems, like the rollers, raceways, cages, and ribs. We need to see if they have any cracks, peeling, rust, scratches, impact marks, or other abnormal places. We also need to measure and evaluate the wear of the cages, the increase of the internal clearance, and the decrease of the tolerances. The results of the inspection can help us decide if the bearings can be used again or need to be replaced.

In summary, checking spherical roller bearings is an important thing to make them work better. We can check them when the machine is running or stopped, depending on what we want and how convenient it is. Checking can help us find and avoid problems, and also make the bearings last longer. So, we need to follow the instructions and standards of the manufacturers, and check the spherical roller bearings regularly and correctly.
