With a wide variety of bearing products on the market, how to select the appropriate bearings has become the focus of attention for numerous enterprises. When choosing bearings, multiple factors need to be comprehensively considered. Firstly, there are load conditions, including the magnitude, direction, and nature of the load. Different types of bearings are suitable for different load situations. For example, deep groove ball bearings are excellent at mainly bearing radial loads and can also bear a certain amount of axial loads, being suitable for high - speed and light - load applications; while tapered roller bearings can simultaneously bear large combined radial and axial loads and are often used in parts such as automotive wheel hubs and machine tool spindles.
Secondly, there is the speed requirement. High - speed rotating equipment needs to select bearings with low friction and high stiffness to ensure stability and reliability at high speeds. In addition, factors such as the temperature, humidity, and corrosiveness of the working environment cannot be ignored. In high - temperature environments, it is necessary to select bearing materials and lubrication methods that can withstand high temperatures; in wet or corrosive media environments, bearings with good corrosion resistance should be chosen.
