In comparison to the general bearing, vibration bearing has many differences.
First of all, vibration bearings have the ability to withstand a greater axial load than general bearings. This is because the contact area of vibration bearing is larger than that of general bearing. The contact area of general bearing is limited on the raceway surface, but the contact area of vibration bearing expands to the rolling element as well. In other words, the greater the contact area, the greater the axial load it can endure. And for this reason, vibration bearings can absorb more radial stresses and achieve a better supporting effect under heavy loads.
Second, the vibration bearing has a larger fatigue life than the general bearing. This is because bearing fatigue is related to the life of the rolling elements and the raceways. The larger contact area of vibration bearing causes the contact force to be distributed more evenly on rolling elements and raceways, thus reducing the local bearing point’s load intensity and prolonging its life.
Third, the installation of vibration bearing is also very convenient. There should be no play between the raceways and the rolling element of vibration bearing and the production of general bearing after installation, while the installation of vibration bearing allows a certain amount of play. This design eliminates the pressure generated during the installation process and reduces the work intensity of personnel, simplifying the overall installation process and further proving the convenience and simplicity of vibration bearing installation.
Fourth, vibration bearing can be applied to various installation environments. In addition to the general external environment or relative movement environment, vacuum environment and low temperature environment, vibration bearing can also be used in special occasions such as food and chemical environments and highly corrosive environments. These special occasions are beyond the reach of general bearings, but perfectly suitable for vibration bearings, demonstrating the wide range of application of the latter.
To sum up, the difference between vibration bearing and general bearing lies in their better axial load capacity, larger fatigue life, convenient installation and wide range of application, etc. With its many advantages, vibration bearing can provide better performance in certain occasions and enjoy a broad application prospect.
