Basic knowledge and advantages of bearing dust seal ring


The bearing sealing ring is an annular cover composed of one or several parts, which is fixed on one ring or washer of the bearing and contacts with another ring or washer or forms a narrow labyrinth gap to prevent leakage of lubricating oil and invasion of foreign objects. The bearing dust seal ring is to prevent dust and grease leakage.
Dust seal ring with its unique sharp lip structure, low friction coefficient. In this way, the sealing ring can prevent external dust from entering the system and reduce the friction of the equipment. It is the basic function of the dust ring to prevent external pollutants from entering the sealing system.
Compared with the prior art, the bearing dust-proof sealing ring adopts a hook shaped crimping structure, which has the following advantages: the bearing dust-proof sealing ring has good sealing performance and high sealing strength. The reason is that the hook shaped crimping structure of the skeleton effectively increases the elasticity of the bearing sealing ring and maximally compensates for the influence of tooth size dispersion. It not only depends on the elasticity of the sealing elastomer, In addition, the elasticity and strength produced by the crimping structure improve the qualified rate of cover installation, and can be pressed by machine, which can be pressed effectively.
The service life of sealed bearing largely depends on its sealing performance. At present, the commonly used bearing sealing ring is a folded skeleton. The bearing sealing ring generally presses the cover by hand. The main disadvantages of bearing sealing ring are: poor elastic strength, poor assembly performance and poor sealing performance.
Advantages of bearing dust seal ring: first, prevent external substances from entering the inside of the bearing. Second, internal grease is reserved. To prevent bearing seal failure.
