How are bearings classified according to their service use?

Bearings are classified according to their service use primarily based on their service weight or load capacity. This classification is essential because it helps in selecting the right bearing for a specific application based on the load it will be subjected to during operation. Each type of bearing has a defined load capacity, which is crucial for ensuring reliability, performance, and longevity in mechanical systems.

When assessing load capacity, engineers consider both the static and dynamic loads that the bearing will experience. This understanding allows for the proper selection of a bearing that can handle the specific weights and forces it will encounter, thus preventing premature failure or inadequate performance in the machine or assembly it is intended for.

Other classifications relating to lubrication, the number of rolling elements, or even outer diameter can be relevant in specific contexts, but they do not directly address how the bearing will perform under its intended service conditions. These aspects may influence a bearing's operation but are secondary when it comes to overall classification based on service use and load handling capabilities.
