Temperature plays a critical role when selecting the right bearing for your application. Whether it's due to friction, electrical currents, electromagnetic induction, or exposure to extreme environmental conditions, bearings often need to perform reliably in high-temperature settings. This article aims to provide you with a deeper understanding of how temperature affects bearing performance and what you can do to ensure long-lasting operation.
Bearings are precision-engineered components, and their proper function depends on maintaining tight tolerances across all parts—races, rolling elements, and cages. For instance, if the outer race expands too much due to heat, it could lead to excessive wear, lubricant leakage, or even failure. Similarly, if the rolling elements deform under high temperatures, the bearing may no longer rotate smoothly, potentially leading to catastrophic failure.
Over time, all bearings experience some degree of wear and material degradation. However, extreme temperatures can significantly accelerate this aging process, reducing both the lifespan and performance of the bearing. This is why it's essential to choose a bearing that is designed to withstand the specific thermal conditions of your application.
At Emerson Bearing, we ensure that our bearings remain dimensionally stable within specified operating temperatures. This means that as long as they are used within the recommended temperature range, their critical dimensions will stay within tolerance limits throughout their service life. This guarantees consistent performance and reliability.
In short, your bearing should function as intended under normal operating conditions. However, if exposed to temperatures beyond the guaranteed range, its lifespan and performance may decrease depending on the load and environmental factors.
Below is a table outlining our dimensionally stabilized bearing categories based on maximum operating temperatures:
