KOYO Brand Bearing Supplier 16026 Thin Wall Ball Bearing

The sealing cover of deep groove ball bearing is mainly used to prevent the intrusion of external foreign bodies (solid foreign bodies, liquid foreign bodies) and prevent the loss of bearing lubricant. There are two sealing forms of bearing seal cover:
1. Non-contact sealing cover (sealing cover and inner ring are not in contact), including stamped steel seal cover (iron seal) and non-contact rubber seal cover. Advantages: dust proof, relatively high speed, metal seal cover relatively low mute effect, relatively low price.
Disadvantages: There is no protection against liquid foreign bodies.
2.Contact sealing cover (sealing cover and bearing inner ring with a single lip or more lip contact), including contact rubber sealing cover and labyrinth type contact sealing cover.
Advantages: dust proof, liquid foreign body prevention, high mute effect.
Disadvantages: slightly lower speed, slightly higher price.
Therefore, there is no difference between good and bad deep groove ball bearing sealing cover, only the difference between suitable. For example: in a clean environment, it is unnecessary to use contact rubber sealing cover, which will only increase the additional cost of the manufacturer.
To sum up, the sealing type of deep groove ball bearing is not good or bad. The main consideration is where the bearing is used and the environmental factors of the bearing need to be considered. The structure of the sealing ring is different, the material is different, and the friction coefficient is different.

Advantages of deep groove ball bearings:

Deep groove ball bearing has the advantages of low manufacturing cost, simple structure, variety and so on. It is widely used in various industries and is one of the more commonly used bearings. It has the following characteristics:
1. Small friction coefficient, high speed.
2.The size range is wide, with a certain aligning ability.
3.Simple structure, low manufacturing cost, mass production, can achieve high precision.
4.Can bear large radial load, when the radial clearance increases, can bear two directions of alternating axial load.
5.In reasonable maintenance and use of the environment of high durability, low maintenance cost.
