How to choose the right bearing to meet your needs

It's important to make sure that the wheel bearings you select are compatible with the application.
Several factors will determine the best bearing for an application, such as load capacity, operating temperature, speed, and lubrication requirements. 
When it comes to loading capacity, bearings are designed to handle either radial or axial loads.
Radial loads exert a force perpendicular to the shaft axis while axial loads exert forces parallel to the shaft axis.
As such, you'll need to identify which type of load your bearing needs to carry to select a suitable product.
Temperature can also affect how well hub bearings performs.
Bearings are typically rated in terms of their maximum operating temperature range and must not be exposed to temperatures beyond this point.
If a bearing is going to be exposed to extreme temperatures, specialized products with enhanced heat resistance are available.
The speed of the application can also affect the type of bearing you selected.
Generally speaking, bearings that operate at higher speeds require additional lubrication or improved designs to prevent premature wear. 
It's also important to think about the level and type of lubricant that will be needed for your specific application.
In some cases, selecting a pre-lubricated bearing may provide benefits.
However, if specialized lubricants need to be used due to environmental or other factors, then you'll need to make sure the bearing is suitable for this purpose. 
By taking all these considerations into account, you can be sure of selecting the most suitable bearing for your needs.
