Differences between different bearing types in terms of different functions
In our daily life, the most common and widely used types of wheel bearings are tapered roller bearings, ball bearings and cylindrical roller bearings. Do you know what is the difference between these three types of bearings in terms of function? Next, we will give you an explanation of the difference between these three types of bearings in terms of four capabilities.
Load carrying capacity
Tapered roller bearings:
Can withstand large radial load and axial load at the same time, suitable for all kinds of goods vehicles, large buses, etc. These vehicles usually need to carry heavier goods or a large number of passengers, the bearing capacity of the wheel hub bearings is required to be higher.
Ball bearings:
Mainly withstand radial load, can also withstand a certain amount of axial load, but the overall bearing capacity relative to tapered roller bearings lower, generally used in small cars, light buses and other relatively small load vehicles.
Cylindrical roller bearings:
Radial bearing capacity is very strong, but the axial bearing capacity is weak, commonly used in some of the radial bearing requirements of high special vehicles or equipment, such as some industrial vehicles, large machinery and equipment wheel parts.
Friction resistance
Tapered roller bearings:
Due to the line contact between the roller and the raceway, and the contact angle is larger, in the operation of the friction resistance is relatively large, which will lead to a certain amount of energy loss, the fuel economy of the vehicle has a certain impact.
Ball bearings:
The ball and the raceway is point contact, friction resistance is smaller, can effectively improve the fuel economy of the vehicle, so that the vehicle is more energy-saving in the driving process.
Cylindrical roller bearings:
The rollers and raceways are also in line contact, and the frictional resistance is between tapered roller bearings and ball bearings, but at high speeds, the frictional heat generation of cylindrical roller bearings is relatively small, and they can better adapt to high-speed working conditions.
Rotation accuracy
Tapered roller bearings:
By adjusting the preload of the bearings, a higher rotary accuracy can be obtained, which can meet the requirements of wheel positioning and steering accuracy of vehicles under various driving conditions.
Ball bearings:
With high rotational accuracy, they can ensure the stability of the wheels in the process of rotation, and provide good maneuvering performance for the vehicle.
Cylindrical roller bearings:
With high rotational accuracy, especially in high speed rotation, they can maintain good stability, reduce vibration and noise, and improve the driving comfort of the vehicle.
Extreme speed
Tapered roller bearings:
Due to its structural characteristics and greater frictional resistance, the limit speed is relatively low, not applicable to high-speed vehicles or equipment.
Ball bearings:
Small friction resistance, high flexibility of ball movement, high limiting speed, suitable for high-speed driving of small cars and some vehicles with higher speed requirements.
Cylindrical roller bearings:
Better performance in high-speed performance, high limiting speed, can meet the needs of some high-speed running machinery and equipment or special vehicles.
