Which is better cylindrical roller bearing or deep groove ball bearing?
1. Definition of deep groove ball bearings and cylindrical roller bearings
Deep groove ball bearings are a kind of spherical bearings, its cross-section is a diameter for the spherical, its axis and bearing mounting datum surface of the normal angle. Cylindrical roller bearing is a kind of rolling bearing, which consists of many cylindrical rollers rolling between the inner ring and outer ring of the bearing.
2. deep groove ball bearings and cylindrical roller bearings advantages and disadvantages.
(1). Advantages and disadvantages of deep groove ball bearings
Advantages: simple structure, low cost, suitable for high-speed operation, easy to maintain and repair.
Disadvantages: bearing capacity is limited, for larger loads and higher speeds, the life of deep groove ball bearings may be shorter.
(2). Advantages and disadvantages of cylindrical roller bearings
Advantages: high load carrying capacity, suitable for high loads and low speeds, long life.
Disadvantages: relatively complex structure, high cost, easy to occur in high-speed operation of lateral sliding, the need for sealing device.
3. deep groove ball bearings and cylindrical roller bearings applications
Deep groove ball bearings are widely used in automobile, motor, agricultural machinery and other fields. Due to their simple structure, low cost and high speed operation, they are suitable for light load working environment.
Cylindrical roller bearings are usually suitable for heavy load, low speed and vibration environment. For example: construction machinery, heavy machinery, metallurgy, mining, shipping, petroleum machinery and so on.
Through the comparison of these two types of bearings, it can be found that each of them has its own applicable environment and field. In the actual application, it is necessary to choose the most suitable bearing type according to the specific situation to ensure the normal operation and life of the equipment.
