What is a common issue caused by improper fitting of a friction bearing?

Improper fitting of a friction bearing can lead to excessive wear and heat generation due to several factors related to how the bearing interacts with its shaft and housing. When a bearing is not fitted correctly, it can create gaps or misalignments that significantly impact its operational efficiency.

This misalignment can result in uneven contact between the bearing surfaces, causing increased friction as the surfaces come into contact at inappropriate angles or with inconsistent pressure. The additional friction not only accelerates wear on the bearing surfaces but also leads to a rise in temperature. As the temperature increases, it can further exacerbate the wear, potentially leading to bearing failure and the need for premature replacement.

In summary, a properly fitted friction bearing is essential for optimal function. Any deviations in fitting can detract from its performance, significantly magnifying wear, heat generation, and, ultimately, the longevity of the bearing itself.
