Choosing the span of a bearing requires considering multiple factors, including the load, speed, size, and application environment of the bearing. Here are some general guidelines:
1. Load: The span of the bearing should be large enough to meet the load requirements. Excessive load may cause bearing wear or damage, while excessive load may cause unstable bearing operation.
2. Speed: High speed running bearings usually require a smaller span to reduce centrifugal force and frictional heat. Bearings running at low speeds can choose larger spans.
3. Size: Select the appropriate span based on the installation space and overall design of the bearing. In limited space, it is necessary to pay attention to the interaction between bearings and other components.
4. Application environment: Considering factors such as working temperature, humidity, and corrosive media, select bearing materials and spans that can adapt to special environments.
