The bearing cover on an electric bicycle plays a crucial role in protecting the bearings and enhancing the riding experience. It not only extends the lifespan of the bearings but also improves the safety of the vehicle. This article will introduce the applications and selection guide of various types of bearing covers on electric bicycles, helping you choose the most suitable bearing cover.
It is commonly referred to as "bearing" in English, while in Taiwan, it is usually called "軸承". The fundamental principle of a bearing involves the placement of rolling elements, such as balls, needles, or rollers, between the inner and outer rings to facilitate smooth rotation of the shaft.
Ceramic bearings encompass materials such as ZrO2 and Si3N4, offering exceptional hardness, high temperature performance, and corrosion resistance. Hybrid ceramic bearings combine ceramic balls with chrome steel or stainless steel inner and outer rings, combining the advantages of both ceramics and metals. They are suitable for high-speed, high-temperature, and corrosive environments, providing improved performance and durability in industrial equipment.
Thrust needle roller bearings are primarily used to withstand axial loads. If both radial and axial loads need to be supported simultaneously, it may be necessary to use other types of bearings or combine different types of bearings to achieve the required support.
Radial axial bearings are crucial components used to support and position rotating mechanical parts. They can withstand axial and radial loads from two directions, allowing mechanical components to operate smoothly and endure external forces. This load-bearing capacity makes radial axial bearings widely used in various applications, including automotive, aerospace, and industrial machinery.
The thrust bearings catalog is an important reference for engineers and designers when selecting appropriate thrust bearings.
