Proper lubrication not only improves the efficiency of the bearing operations. It also prolongs its longevity drastically.
The interchangeability of the 30207X bearing with other bearing models largely depends on the specifications of the other model. For instance, other bearings with the same outer diameter, inner diameter, and width can fit into the same housing and bore. Even so, there may be slight distinctions in the load ratings, bearing clearance, and sealing configurations.
That is why it is always best to consult the manufacturer's catalog when finding an interchangeable bearing. In situations where it's possible to use a different bearing, one must ensure the bearings are compatible with the application requirements. It will help maintain optimal performance.
The use of the incorrect size bearing can have a myriad of disastrous consequences. One such consequence is improper load distribution. When the size is smaller or larger than required, the load cannot be equally spread. Ultimately, the bearing and adjacent machine components will wear out unevenly. The bearing will overheat as a result of increased friction. At times when overheating occurs, the lubricants will break down. Thus, leading to equipment failure.
An incorrect bearing size will most definitely lead to uncomfortable and inconvenient break times to try and fix the failures. It doesn't end there. There can even be excessive vibration and noise during the operation due to poor fitment. Lastly, it may void machine warranties because many manufacturers will specify the correct bearing size based on the equipment. It's needless to say that this mistake is costly, and it risks safety, equipment, and productivity.
