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 function reliably in high-temperature environments. This article aims to provide you with a deeper understanding of how temperature affects bearing performance and what it takes for your bearing to withstand heat effectively.
Bearings are precision components, and their proper operation depends on all parts—races, rolling elements, and cages—maintaining tight engineering tolerances. For instance, if the outer race expands too much, it can lead to excessive wear, lubricant leakage, or even failure. Similarly, if any of the rolling elements deform under heat, the bearing may lose its smooth operation, potentially leading to a catastrophic failure.
Over time, bearings naturally age as the steel undergoes expansion, deformation, or wear, which can affect their internal clearances and tolerances. While aging is typically a slow process, extreme temperatures can significantly speed up this deterioration. That’s why it's essential to choose bearings that are designed to handle the specific thermal conditions of your application.
At Emerson Bearing, we ensure that our bearings maintain dimensional stability within specified operating temperatures. This means that as long as they’re used within their recommended temperature range, their key dimensions will remain within tolerance limits throughout their service life. This guarantees consistent performance and reliability, even under demanding conditions.
In short, your bearing should perform as intended under normal operating conditions. However, when exposed to temperatures outside the guaranteed range, its lifespan and performance may decrease depending on the load and environmental factors. It’s important to account for these variables when selecting the right bearing for your system.
Below is a table outlining our dimensionally stabilized bearing categories based on maximum operating temperatures:
