What should be considered when selecting bearing materials in relation to water exposure?

When selecting bearing materials in relation to water exposure, dimensional stability is a crucial factor to consider. Materials that maintain their size and shape when exposed to moisture are essential for ensuring optimal performance in applications where water is a factor. If a bearing material expands or contracts significantly with changes in moisture levels, it could lead to improper fit and alignment, resulting in increased wear, vibrations, or even failure of the bearing system.

Choosing materials with good dimensional stability under wet conditions helps maintain the integrity of the bearing assembly, ensures effective load distribution, and prolongs the lifespan of both the bearing and the machinery it supports. It allows for consistent performance, which is particularly important in industries where equipment may be exposed to fluctuating humidity and temperatures. This consideration is vital for reliability and safety in mechanical systems.
